WARNING

New tires or tires that are old, worn or damaged cannot provide maximum control and
braking performance.

Improper care and handling of tires and wheels can reduce driving safety and cause

accidents and severe injuries.

Install only radial tires of the same make, the same dimensions (tread circumference), and

similar tread profile on all 4 wheels.

New tires tend to be slippery and must be broken in. Always drive with special care for the

first 350 miles (560 km) to help reduce the risk of losing control, a collision, and serious
personal injuries.

Check tire inflation pressure regularly when the tires are cold and always maintain the

prescribed tire pressure. Low tire pressure can cause tires to get too hot, resulting in tread
separation, sudden loss of pressure, and blowouts. Tires with excessively low pressure flex
(bend) more, which can cause the tire to overheat and fail suddenly without warning.

Check tires regularly for wear and damage.
Never drive with worn or damaged tires (for example, tires with punctures, cuts, cracks,

blisters, or bumps). Driving with worn or damaged tires can lead to loss of vehicle control,
sudden tire failure including blowouts and sudden deflation, crashes, and serious personal
injuries.

Have worn or damaged tires replaced immediately.
Never exceed the maximum speed rating or the maximum load rating of the tires on your

vehicle.

The effectiveness of the driver assistance systems and the braking support systems

depends on the tire traction.

If you notice unusual vibration or if the vehicle pulls to one side when driving, always stop

as soon as it is safe to do so and check the wheels and tires for damage.

To reduce the risk of losing control, crashes, and serious personal injuries, never loosen

the bolts on wheels with bolted rim rings.

Never mount used tires on your vehicle if you are not sure of their past use. Old, used

tires and wheels may have damage that cannot be seen that can lead to sudden tire failure
and loss of vehicle control.

Tires age even if they are not being used and can fail suddenly, especially at high speeds,

causing loss of vehicle control, accidents, and severe personal injuries. Tires that are more
than 6 years old can be used only in an emergency and even then only with special care and
at low speed.

For technical reasons it is usually not possible to use wheel rims from other vehicles. Even wheel

rims from the same model may not fit properly. Check with an authorized Volkswagen dealer or
authorized Volkswagen Service Facility if necessary.

Tire and wheel handling

Fig. 104 Tire rotation diagram.

Please first read and note the introductory information and heed the WARNINGS

Tires may be the least appreciated and most abused parts of a motor vehicle. Tires are very important,
since their small patches of rubber are the only contact between your vehicle and the road.

Maintaining correct tire pressure, making sure that your vehicle and its tires do not have to carry more
weight than they can safely handle, and regularly inspecting tires for damage (such as cuts, slashes,
irregular wear, and overall condition) are the most important things that you can do to help avoid
sudden tire failure, including tread separation and blowout.

The tires and wheels are essential parts of the vehicle's design. The tires and wheels approved by
Volkswagen are specially matched to the characteristics of the vehicle for good road holding and safe
handling when in good condition and properly inflated.

Avoiding tire damage

If you must drive over a curb or other obstacle, drive very slowly and as much as possible at a right

angle to the curb with the tire tread of both front wheels contacting the curb at the same time.

Regularly check tires for damage, such as punctures, cuts, tears and blisters.
Remove embedded material in the tread profile that has not yet penetrated the inside of the tire

⇒ Tire wear and damage.

Heed all warning messages from the Tire Pressure Monitoring System

Replace worn or damaged tires immediately

⇒ Tire wear and damage.

Damage to tires and wheels is often not readily visible. If you notice unusual vibration or the

vehicle pulls to one side, this may indicate that one of the tires is damaged. The tires must be checked
immediately for hidden damage by an authorized Volkswagen dealer or an authorized Volkswagen

Service Facility. See also

⇒ Tire wear and damage.

Never exceed the load and permissible maximum speed rating of the tires

⇒Tire labeling.

Always keep aggressive chemicals including grease, oil, gasoline and brake fluid off the tires,

including the compact spare wheel

⇒

.

Replace missing valve caps immediately.

Unidirectional tires

Unidirectional tires are designed to rotate only in one direction. Unidirectional tires have arrows on the

sidewalls that show the direction of rotation

⇒ Tire labeling. Unidirectional tires must always be

mounted according to the specified direction of rotation in order to deliver their best grip, braking
performance, low road noise, and good wear as well as good hydroplaning resistance.

If you have to mount a tire opposite to its proper direction of rotation, you must drive more carefully,
since the tire is no longer being used as designed. This is particularly important on wet roads. You
must replace or remount the tire as soon as possible in order to restore the correct direction of
rotation.

Rotating tires

To help ensure even wear on all tires, regular tire rotation according to the diagram

⇒

fig. 104

is

recommended. In this way all tires can have about the same service life.

Volkswagen recommends that you have your tires rotated by an authorized Volkswagen dealer or
authorized Volkswagen Service Facility.

Tires more than 6 years old

Tires age even if they are not being used. Physical and chemical processes reduce tire strength and
performance and cause them to harden and become brittle. Old tires can fail suddenly and without
warning.

Volkswagen recommends replacing tires that are 6 years and older. This also applies to tires that look
new (including the tire on the compact spare wheel) or that seem to still be usable with tread depth

that has not yet reached the legal minimum depth

⇒

.

The age of each tire can be determined with the manufacturing date that is part of the U.S. DOT tire

identification number ( )

⇒ Tire labeling.

Tire storage

Mark tires before removing them to help make sure that the previous location (left, right, front, rear)
and rolling direction can be maintained when remounting them. Store tires in a cool, dry and preferably
dark place. Do not store tires mounted on wheels standing up.

Tires not mounted on wheels should be covered to help protect them from dirt and stored vertically
(sitting on the tread).

WARNING

Aggressive fluids and materials can cause visible and invisible tire damage that can cause
tire blowouts.

Always keep chemicals, oils, grease, fuels, braking fluids and other aggressive

substances away from tires.

WARNING

Tires age even if they are not being used and can fail suddenly, especially at high speeds,
causing loss of vehicle control, accidents, and severe personal injuries.

Tires that are more than 6 years old can be used only in an emergency and even then only

with special care and at low speed.

Always dispose of old tires in accordance with legal requirements.

Wheel rims

Please first read and note the introductory information and heed the WARNINGS

The design of the wheel bolts is matched to the factory-installed wheels. If different wheels are
installed, wheel bolts with the right length and bolt head shape must be used. This helps to ensure that

wheels can be mounted securely and that the brakes will work correctly

⇒ Changing a wheel.

In most cases, you cannot use wheel bolts from a different vehicle. Even wheel rims from the same
model may not fit properly.

Tires and wheel rims approved by Volkswagen have been matched precisely to your vehicle model
and contribute considerably to good handling and safe vehicle performance.

Tightening torque

Wheel bolts must always be installed with the correct tightening torque. The required tightening torque
for your vehicle's wheel bolts is 88 ft-lbs (120 Nm). After changing a wheel, the bolt torque must be
checked as soon as possible with an accurate torque wrench. See an authorized Volkswagen dealer
or an authorized Volkswagen Service Facility.

Wheel rims with bolted rim rings

Wheel rims with bolted rim rings have several parts. The parts are bolted together with special screws
in a special process. This helps to ensure that they will work properly, prevent leaks, run true and
safely. Damaged wheel rims must be replaced, and you must never take them apart or try to repair
them yourself. Have an authorized Volkswagen dealer or an authorized Volkswagen Service Facility

repair them for you

⇒

.

Wheel rims with bolted decorative covers

Light-alloy wheels may have interchangeable decorative covers attached to the rim with self-locking
screws. If you want to replace damaged wheel covers, contact your authorized Volkswagen dealer or
authorized Volkswagen Service Facility.

WARNING

Using improper or damaged wheel rims can affect driving safety, cause accidents and severe
personal injury.

Use only wheel rims approved for the vehicle.
Regularly check wheel rims for damage and replace them if necessary.

WARNING

Improper loosening and tightening of the bolts on wheel rims with bolted rim rings can cause
accidents and severe personal injury.

Never loosen bolted connections on wheel rims with bolted rim rings.
Have all work on wheel rims with bolted rim rings performed by an authorized Volkswagen

dealer or authorized Volkswagen Service Facility.

New and replacement tires

Please first read and note the introductory information and heed the WARNINGS

New tires

Drive a vehicle with new tires especially carefully for the first 350 miles (560 km) because the tires

must first be broken in. Tires that are not broken in have reduced traction and braking performance

⇒

.

Install only radial tires only of the same make, the same dimensions (tread circumference), and

similar tread profile on all 4 wheels.

The tread depth of new tires can differ between tire models and manufacturers because of different

design features and tread design.

Replacing tires

Tires should be replaced in pairs and not individually (both front tires or both rear tires at the same

time)

⇒

.

Replace tires only with tires that have the same specifications, including width and diameter, load

and top speed rating as the tires approved by Volkswagen for your vehicle and model.

Never use tires that are larger or wider than the dimensions of the tires approved by Volkswagen

for your vehicle and model. Larger tires could scrape and rub on the vehicle body or other parts of the
vehicle.

Tire Pressure Monitoring System (TPMS) considerations

Factory-installed wheels are equipped with a sensor that constantly monitors tire pressure, then

transmits this information to the TPMS

⇒ Tire Pressure Monitoring System (TPMS). If you are going to

replace the wheels, make sure that the new wheels also have sensors that are compatible with the
TPMS on your vehicle. New wheels with sensors have to be recognized and integrated into the
system. The new wheels and sensors are recognized and integrated when driving off the first time.

If you install wheels that do not have sensors, or have sensors that are not compatible, the TPMS will
not work properly. In this case, the TPMS will not be able to monitor tire pressure or warn you if
pressure is low. An error message may appear in the instrument cluster display or the TPMS will
switch itself off.

Whenever you change sensors, you have to install new valves and seals. Please see an

authorized Volkswagen dealer of an authorized Volkswagen Service Facility.

Always drive with the valve caps securely installed. We recommend using factory-supplied valve

caps. Ask an authorized Volkswagen dealer or an authorized Volkswagen Service Facility to replace
lost caps.

If you install new tires that differ the original Volkswagen specifications, for your vehicle and model, the
benchmark tire inflation pressure values stored in your vehicle's TPMS may have to be adjusted
(reprogrammed). This requires professional assistance. For more information, contact your authorized
Volkswagen dealer or authorized Volkswagen Service Facility.

Installing replacement tires with steel cord body plies in the tire sidewall may cause malfunction of the
TPMS, and is not recommended (cord material information in molded on the tire sidewall).

Always check the TPMS indicator light after replacing one or more tires on your vehicle. If the indicator
light is on, the TPMS is not working properly. Your replacement tire might be incompatible with the
system, or some component of the TPMS may be damaged.

For detailed information about TPMS, how it works and what you need to know

⇒ Tire Pressure

Monitoring System (TPMS).

WARNING

New tires tend to be slippery and must be broken in.

Always drive with special care for the first 350 miles (560 km) to help reduce the risk of

losing control, a collision, and serious personal injuries.

WARNING

Tires must have the required clearance. Tires that do not have enough clearance can rub
against parts of the vehicle body, suspension, and brake system, causing brake system
failure, tread delamination, and sudden blowouts.

Always make sure that new tires are not larger than the tires approved for your vehicle

and that the new tires do not rub against parts of the vehicle.

NOTICE

When switching to different tires, make certain the valves and sensors are not damaged.
Never drive without valve stem caps. The valves and sensors could be damaged.
If a sensor for the Tire Pressure Monitoring System must be replaced, the corresponding

valve must be replaced at the same time.

Always dispose of old tires in accordance with legal requirements.

TPMS wheel sensors are classified as Perchlorate Material – special handling may apply. Obey

all legal requirements regarding handling and disposal of these components – see
http://www.dtsc.ca.gov/hazardouswaste/perchlorate. Obey all applicable legal requirements regarding
handling and disposal of the vehicle or parts of its restraint system, including airbag modules and
safety belts with pretensioners. Authorized Volkswagen dealers and authorized Volkswagen Service
Facilities are familiar with the requirements, and we recommend that you have them perform this
service for you.

If the replacement wheel is different from the tires that you have mounted on your vehicle — for

example, winter tires, wider, low-profile tires or a compact spare — only use the replacement wheel for
a short time and drive cautiously.

Replace it with a tire matching the others on your vehicle as soon as possible.

Although tire size specifications can be the same, the actual dimensions may differ from those

nominal values for different tire makes, or the tire contours may be significantly different.

Tire inflation pressure

Fig. 105 On the driver door jamb: Location of the tire inflation pressure label.

Please first read and note the introductory information and heed the WARNINGS

The correct tire inflation pressure for the factory-installed tires is listed on a label. The factory-installed

tires may be summer, winter, or all-season tires. The label

⇒

fig. 105

is on the driver door jamb.

Under- or over-inflation significantly shortens the service life of your tires and affects the handling of

the vehicle

⇒

. The correct tire pressure is very important, particularly when the vehicle is driven at

higher speeds. Incorrect tire pressure causes increased wear and even sudden tire failure and
blowouts.

Therefore, tire pressure should be checked at least once a month and always before long trips.

The specified tire inflation pressure applies to a cold tire. When tires are warm, the pressure will be
higher than when the tires are cold.

Do not reduce the tire pressure on warm tires to match the required cold tire inflation pressure. The
tire inflation pressure would then be too low and could cause sudden tire failure and blowout.

Checking tire inflation pressure

Always check the tire pressure only on “cold” tires when the vehicle has not been driven more than a
couple of miles (kilometers) at low speed within the last 3 hours.

Check tire inflation pressure regularly and on cold tires. Check all the tires, including the compact

spare, if any. In colder climates tire pressure should be checked more often, but only when the tires
are cold. Always use an accurate tire pressure gauge.

After adjusting the tire inflation pressures, make sure to screw the valve caps back on; replace

missing valve caps immediately. Please read and heed the information on resetting the Tire Pressure
Monitoring System

Remember that the vehicle manufacturer, not the tire manufacturer, determines the correct tire

pressure for the tires on your vehicle. Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.

Inflate a spare wheel to the pressure specified for the vehicle's road wheels on the tire pressure label;
inflate the compact spare wheel to the pressure specified for the compact spare on the tire pressure
label or on a separate label for the compact spare, if there is one.

WARNING

Incorrect tire pressure can cause a sudden tire failure or blowout, loss of control, collision,
serious personal injury, and even death.

Always inflate tires to the recommended and correct cold tire pressure before driving off.
Low tire pressure can cause tires to get too hot, resulting in tread separation, sudden loss

of pressure, and blowouts. Tires with excessively low pressure flex (bend) more, which can
cause the tire to overheat and fail suddenly without warning.

Excessive speed and/or overloading can cause heat build-up, sudden tire failure including

a blowout and sudden deflation and loss of control.

If the tire pressure is too low or too high, the tires will wear prematurely and the vehicle

will not handle well.

Regularly check tire inflation pressure, at least once a month, and also especially before a

long trip.

Check the pressure in all 4 tires when the tires are still cold. Never reduce air pressure in

warm tires to match cold tire inflation pressure.

NOTICE

Make sure not to jam the tire pressure gauge into the valve stem. Otherwise, you can

damage the tire valves and the tire inflation pressure sensors

⇒ page 189.

Driving without valve caps, with the wrong valve caps, or with valve caps that are not

properly screwed on can damage the tire valves and the sensors on the Tire Pressure

Monitoring System

⇒ page 189. To help prevent damage, always use valve stem caps like those

originally installed at the factory. The caps must be screwed on tightly. Do not use metal valve
caps or “comfort” valve stem caps.

Underinflated tires increase fuel consumption.

There may be differences between the pressure readings from a tire pressure gauge and the

pressures registered by the Tire Pressure Monitoring System. The electronic Tire Pressure Monitoring
System is more accurate.

When the TPMS warns that the pressure in at least one tire is too low, check the tire pressure in

all 4 tires with an accurate tire pressure gauge. Low tire pressure usually cannot be spotted by looking
at the tire. This is especially true for low-profile tires. When checking the tire pressures, refer to

The Tire Pressure Monitoring System is configured at the factory with the correct tire inflation
pressure applicable for the vehicle model, engine and factory-installed tires. The tire inflation

pressure is listed on the tire inflation pressure label on the driver door jamb

⇒ Tire inflation pressure.

The tire inflation pressures for the road tires are listed on this label. The inflation pressure for the
compact spare is as specified on the tire pressure label or on a separate label for the compact
spare, if there is one. In the event of a discrepancy between the above figures and the tire pressures
listed on the tire inflation pressure label, the pressures listed on the label are the ones you should
use. The listed pressure applies to all road tires. If different tires are installed that do not have the
same cold tire inflation pressure as the tires originally installed on your vehicle, the Tire Pressure
Monitoring System cannot properly monitor tire inflation pressures unless the TPMS is reset to the
new tire pressures. Authorized Volkswagen dealers and authorized Volkswagen Service Facilities
have the necessary special tools and can reset the TPMS for the new tires on your vehicle.

Tread depth and tread wear indicators

Fig. 106 Tread pattern: Wear indicator.

Please first read and note the introductory information and heed the WARNINGS

Tread depth

Most driving situations require as much tread depth as possible and similar tread depth for the tires on
the front and rear wheels. This is especially true when driving in winter weather, at low temperatures

and under wet conditions

⇒

.

In most countries the legally permissible minimum tread depth is 1/16 in. (1.6 mm), as measured in
tread grooves next to the wear indicators. Please be sure to obey country-specific legal requirements.

Winter tires are no longer suitable for winter operation once the tread pattern is worn down to a depth
of 3/16 in. (4.8 mm).

The tread depth of new tires can differ between tire models and manufacturers because of the
different design features and tread patterns.

Tread wear indicator (TWI) in the tire

The 1/16 in. (1.6 mm) high wear indicators are molded into the bottom of the tread grooves of the

original tires running across the treads

⇒

fig. 106

. Several wear indicators are evenly spaced around

the tire. Markings on the sides of the tires (for example “TWI” or symbols) show the position of the
wear indicators.

Wear indicators show when the tires are worn down. The tires must be replaced no later than when
the tread pattern is worn down to the wear indicators.

WARNING

Worn tires are dangerous and can cause loss of vehicle control including serious personal
injuries.

Never drive a vehicle when the tread on any tire is worn down to the wear indicators,

replace them sooner.

Worn tires do not grip the road properly, especially on wet roads, increasing your risk of

“hydroplaning” and loss of control.

Worn tires reduce the ability of your vehicle to handle well in normal and difficult driving

situations and increase braking distances and the risk of skidding.

Tire wear and damage

Please first read and note the introductory information and heed the WARNINGS

Wheel rim and tire damage is often difficult to see. Unusual vibrations or pulling to one-side can be

an indication of tire damage

⇒

.

If you suspect tire damage, immediately reduce speed!
Check tires and wheel rims for damage.
If a tire is damaged, do not drive any farther. Get expert assistance.
If no external damage is visible, slowly and carefully drive to the nearest authorized Volkswagen

dealer, authorized Volkswagen Service Facility, or other qualified workshop and have the vehicle
checked.

Objects embedded in the tire

If embedded objects have penetrated to the inside of the tire, do not remove them! If objects are

stuck in the tread grooves of the tire, they can be removed.

If necessary, change the damaged wheel

⇒ Changing a wheel. If necessary, get professional

assistance to change the wheel.

Check tire pressure and adjust if necessary.

Tire wear

Tire wear depends on several factors, including:

Driving style.
Unbalanced wheels.
Wheel alignment.

Driving style – Fast cornering, hard acceleration and braking increase tire wear. If you experience
increased tire wear under normal driving conditions, have the vehicle suspension checked by an
authorized Volkswagen dealer or an authorized Volkswagen Service Facility.

Unbalanced wheels – The wheels on a new vehicle are balanced. When driving, however, various
conditions can cause a wheel to become unbalanced. Unbalanced wheels can cause wear to the

steering and suspension systems. Have all wheels rebalanced. A wheel must always be rebalanced if
a new tire has been mounted.

Wheel alignment – Incorrect wheel alignment causes excessive and uneven tire wear, impairing
vehicle safety. If you notice excessive or uneven tire wear, have the wheel alignment checked by an
authorized Volkswagen dealer or an authorized Volkswagen Service Facility.

WARNING

Unusual vibrations or pulling to one side can indicate tire damage.

Reduce speed immediately and stop when it is safe to do so.
Check tires and wheel rims for damage.
Never drive with a damaged tire or rim. Get expert assistance instead.
If no external damage is visible, slowly and carefully drive to the nearest authorized

Volkswagen dealer, authorized Volkswagen Service Facility, or other qualified workshop and
have the vehicle checked.

Stowing the replaced wheel

Lift up the luggage compartment cover and latch it by slipping its hooks over the tabs.
Hook the floor covering on the upper edge of the luggage compartment.
If the wheel you took off the vehicle fits in the spare wheel well, position it so that the center hole of

the rim is aligned with the threaded pin in the center of the well.

Turn the handwheel clockwise until the wheel is securely in place.
If necessary, return the vehicle tool kit to its location in the luggage compartment.
Unhook the floor covering and fold it back down onto the floor of the luggage compartment.
Close the luggage compartment lid.

If the replaced wheel does not fit in the spare wheel well, stow it securely in the luggage compartment
on top of the floor covering.

Differences between the road tires and the compact spare

The compact spare is different in design from the road tires and must be used only in the event of a

flat tire, only for a brief time, and only when driving with extra caution

⇒

.

Replace it with a tire matching the others on your vehicle as soon as possible.

Please heed the following:

Do not drive faster than 50 mph (80 km/h)!
Avoid full-throttle acceleration, hard braking and fast cornering!

Do not use snow chains on the compact spare wheel

⇒ Snow chains.

After installing the compact spare wheel, check the tire pressure as soon as possible

⇒ Tire

inflation pressure.

Check the tire inflation pressure of the spare or compact spare whenever you check the tire pressure
of the road wheels, at least once a month. Inflate a compact spare wheel to the cold tire pressure
specified for the compact spare on the tire pressure label or on a separate label for the compact spare,
if there is one.

WARNING

Improper use of a compact spare wheel can cause loss of vehicle control, a crash or other
accident, and serious personal injury.

Never use a compact spare wheel if it is damaged or worn down to the wear indicators.
In some vehicles, the compact spare wheel is smaller than the original tire. A smaller

compact spare wheel is identified with a sticker and the words “50 mph” or “80 km/h.” This is
the maximum permissible speed when driving with this tire.

Never drive faster than 50 mph (80 km/h) with a compact spare wheel. Avoid full-throttle

acceleration, heavy braking, and fast cornering!

Never drive more than 125 miles (200 km) if a compact spare wheel is installed on the front

axle (drive axle).

Replace the compact spare with a normal wheel and tire as soon as possible. Compact

spare tires are designed for brief use only.

Regularly check the U.S. DOT Tire Identification Number (TIN) to determine the age of the

compact spare wheel

⇒ Tire labeling. Tires age even if they are not being used and can fail

suddenly, especially at higher speeds.

Tires that are more than 6 years old can only be used in an emergency and then with

special care and at lower speeds.

The compact spare wheel must always be secured with the wheel bolts provided by the

factory.

Never drive using more than one compact spare wheel.
After installing the compact spare wheel, the tire pressure must be checked as soon as

possible

⇒ Tire inflation pressure.

Snow chains cannot be used on the compact spare wheel. If you must use snow chains

and have a compact spare wheel mounted, move the compact spare wheel to the rear axle if a
front tire has to be replaced. The tire taken off the rear axle can then be used to replace the
flat front tire. Be sure you do not change the tire's direction of rotation. Install the snow
chains on the full-sized road tire.

NOTICE

The spare wheel or compact spare wheel has no tire pressure sensor. When the spare or
compact spare wheel is mounted on the vehicle, the Tire Pressure Monitoring System (TPMS)
indicator light will flash in the instrument cluster display.

If possible, attach the compact spare wheel or the wheel you took off the vehicle securely in the

luggage compartment.
