Smart fortwo (2016). Instruction — part 12

Optionally, tires with a maximum speed of

over 149 mph (240 km/h) may have "ZR" in the

size description, depending on the manufac-

turer (e.g. 245/40 ZR 18).

Rim diameter: rim diameter ? is the diam-

eter of the bead seat, not the diameter of the

rim flange. The rim diameter is specified in

inches (in).

Load-bearing index: load-bearing index A

is a numerical code that specifies the maxi-

mum load-bearing capacity of a tire.

Do not overload the tires by exceeding the

specified load limit. The maximum permis-

sible load can be found on the vehicle's Tire

and Loading Information placard on the

B-pillar on the driver's side (

Y

page 185).

Example:

Load-bearing index 91 indicates a maximum

load of 1,356 lb (615 kg) that the tires can bear.

For further information on the maximum tire

load in kilograms and lbs, see (

Y

page 193).

For further information on the load bearing

index, see "Load index" (

Y

page 193).

Speed rating: speed rating B specifies the

approved maximum speed of the tire.

i

Tire data is vehicle-specific and may

deviate from the data in the example.

Regardless of the speed rating, always

observe the speed limits. Drive carefully and

adapt your driving style to the traffic con-

ditions.

Optionally, tires with a maximum speed of

over 149 mph (240 km/h) may have "ZR" in the

size description, depending on the manu-

facturer (e.g. 245/40 ZR18).

The service specification is made up of

load-bearing index A and speed rating

B.

R

If the size description of your tire

includes "ZR" and there are no service

specifications, ask the tire manufacturer

in order to find out the maximum speed.

If a service specification is available, the

maximum speed is limited according to the

speed rating in the service specification.

Example: 245/40 ZR18 97 Y. In this example,

"97 Y" is the service specification. The

letter "Y" represents the speed rating. The

maximum speed of the tire is limited to

186 mph (300 km/h).

R

The size description for all tires with

maximum speeds of over 186 mph (300 km/h)

must include "ZR", and the service speci-

fication must be given in parentheses.

Example: 275/40 ZR 18 (99 Y). Speed rating

"(Y)" indicates that the maximum speed of

the tire is over 186 mph (300 km/h). Ask the

tire manufacturer about the maximum

speed.

An electronic speed limiter prevents your

vehicle from exceeding a speed of 130 mph

(210 km/h).

The speed rating of tires mounted at the fac-

tory may be higher than the maximum speed

that the electronic speed limiter permits.

Make sure that your tires have the required

speed rating, e.g. when buying new tires. The

required speed rating for your vehicle can be

found in the "Tires" section (

Y

page 200).

Further information about reading tire data

can be obtained from any qualified special-

ist workshop.

Load index

In addition to the load-bearing index, load

rating : may also be imprinted on the side-

wall of the tire. This is located after the let-

ters that identify the speed rating

DOT, Tire Identification Number (TIN)

U.S tire regulations prescribe that every tire

manufacturer or retreader must imprint a TIN

in or on the sidewall of every tire produced.

The TIN is a unique identification number.

The TIN enables the tire manufacturers or

retreaders to inform purchasers of recalls

and other safety-relevant matters. It makes it

possible for the purchaser to easily identify

the affected tires.

The TIN is made up of manufacturer identi-

fication code ;, tire size =, tire type

code ? and manufacturing date A.

Changing a wheel
Flat tire

You can find information on what to do in the

event of a flat tire in the "Flat tire" section

(

Y

page 161).

Rotating the wheels

G

WARNING

Never interchange the front and rear wheels

as they have different dimensions, e.g.

size, wheel offset etc. Otherwise, there

could be a negative effect on the road hold-

ing and you could endanger yourself or oth-

ers.

!

On vehicles equipped with a tire pressure

monitor, electronic components are loca-

ted in the wheel.

Tire-mounting tools should not be used

near the valve. This could damage the elec-

tronic components.

Only have tires changed at a qualified spe-

cialist workshop.

Various types of steel wheel can be fitted on

your vehicle. Some steel wheels have a red

mark in the hub cap area. The hub cap has to be

removed to see the red mark, see "Raising the

vehicle" in the "Wheel change" section

(

Y

page 197). When changing the wheels,

always fit wheels of the same type on all axles.

Always pay attention to the instructions and

safety notes when changing a wheel

(

Y

page 196).

The wear patterns on the front and rear tires

differ, depending on the operating condi-

tions. Front tires typically wear more on the

shoulders and the rear tires in the center.

Clean the contact surfaces of the wheel and

the brake disc thoroughly every time a wheel

is rotated. Check the tire pressure and reac-

tivate the tire pressure monitor if necessary.

Direction of rotation

Tires with a specified direction of rotation

have additional benefits, e.g. if there is a

risk of hydroplaning. These advantages can

only be gained if the tires are fitted corre-

sponding to the direction of rotation.

An arrow on the sidewall of the tire indicates

its correct direction of rotation.

Storing wheels

Store wheels that are not being used in a cool,

dry and preferably dark place. Protect the

tires from oil, grease, gasoline and diesel.

Wheel and tire combinations
General notes

!

For safety reasons, smart recommends that

you only use tires and wheels which have

been specifically approved by smart for

your vehicle. These are specially adapted

to the control systems, such as ABS or ESP

®

.

Only use tires and wheels specifically tes-

ted and approved by smart. Certain char-

acteristics, e.g. handling, vehicle noise

emissions or fuel consumption, may other-

wise be adversely affected. In addition,

when driving with a load, dimensional var-

iations and different tire deformation

characteristics could cause the tires to

make contact with the bodywork and axle

components. This could result in damage to

the tires or the vehicle.

fied or incorrectly retrofitted RF-trans-

mitters can interfere with the vehicle

electronics. This can compromise the

operational safety of the vehicle. There is

a risk of an accident.
You should have all work to electrical and

electronic equipment carried out at a

qualified specialist workshop.

G

WARNING

The electromagnetic radiation from incor-

rectly operated RF transmitters can inter-

fere with the vehicle electronics, for

example:

R

if the RF transmitter is not connected

with an exterior antenna

R

the exterior antenna has been installed

incorrectly or is not a low-reflection

type

This can compromise the operational safety

of the vehicle. There is a risk of an acci-

dent.
Have the low-reflection exterior antenna

mounted at a qualified specialist work-

shop. When operating RF transmitters in

the vehicle, always connect them with the

low-reflection exterior antenna.

!

The operating permit may be invalidated

if the instructions for installation and use

of RF transmitters are not observed.

In particular, the following conditions

must be complied with:

R

only approved wavebands may be used.

R

compliance with the maximum permissi-

ble output in these wavebands is

required.

R

only approved antenna positions may be

used.

Excessive levels of electromagnetic radia-

tion may cause damage to your health and the

health of others. Using an exterior antenna

takes into account current scientific discus-

sions relating to the possible health hazards

that may result from electromagnetic fields.

The following antenna positions may be used

if RF transmitters have been properly instal-

led:
