belt‘s edge for cracking or abrasion.
Mitsubishi 4G69S4M engine‘s automatic
senility adjustment installation can adjust
the senility of driving belt. The finger on it
should be in appropriate range. Examine it
according to recommended driving time and
mileage in the periodical maintenance
schedule.

Tire

To safely drive your vehicle, your tires must
be the proper type and size, in good
condition with adequate tread and correct
tire pressure. The following pages give
more detail information on how to and
when check the tire pressure, and how to
check the damage and abrasion of tires, and
the operation method when replacing tire.

Friendly tips

Using tires that excessive abrasion or
tire pressure deficiency can cause a
crash in which you may be seriously
hurt or killed.

Notice

Follow all instructions in this owner‘s
manual regarding tire charging and
maintenance.

Tire charging
Keeping

the

tires

properly

charging

provides the best combination of handling,
tread life and riding comfort. Charging
deficiently of tires wear unevenly, adversely
affect handling and fuel economy and more
likely to fail from being overheated.
Charging excessively of tires can make your
vehicle ride more harshly, are easier to
damage from road hazard, and wear
unevenly.

Advice that you visually check your vehicle
every day. If you think a tire might be low,
check it immediately with a tire gauge.

Use a gauge to measure the tire pressure in
each tire at least once a month. Even tires
that are in good condition may lose 7 to
15kPa (0.07 to 0.15kgf/cm) per month.
Remember to check all the tires at the same
time including spare tire.
Check the tire pressure when the tires are
cold. This means the vehicle has been
parked for at least 3 hours. If you must
measure it before driving, the tire can still
be considered as cold as long as driven less
than 1.6km.

If you check tire pressure when the tires are
hot (driven for several miles), you will see
readings 30 to 40kPa (0.3 to 0.4kgf/cm)
higher than the cold readings. This is
normal. Do not let air cut to match the
recommended cold tire pressure; it will
cause the tire pressure deficiency.

You should get your own tire pressure
gauge and use it whenever you check your
tire pressure. This will make easier for you
to judge if a pressure loss is due to a tire
problem and not due to a variation between
gauges.

Recommended tire pressure
Refer to the tire placard on driver‘s
doorjamb for correct tire pressure.

When tire without inner tube is implanted, it
has self-closed function. However, leakage
is usually very slow. So you should look for
the leakage position as long as the tire
begins to decrease pressure.

BYD AUTO F6 OWNER’S MANUAL

123

Inspection
Every time you check tire charging
condition, you should also examine the tires
for damage, foreign objects, and abrasion.
You should look for:
1. Damage and bulges in the tread or side of
the tire. Replace the tire if you find either of
these conditions.

2. Cuts, splits or cracks in the side of tire.
Replace the tire if you see fabric or cord.

3. Excessive tread wear.

Your tires have wear marks molded into
tread. When the tread wears down, you will
see a band wide across the tread. This shows
there is less than 1.6mm of tread left on the
tire. A tire this worn gives very little
adhesive force on wet road. You should
replace the tire if you see three or more
tread wear marks.

Maintenance
In addition to properly charging, correct
wheel alignment helps to decrease tire wear.
If you find a tire is worn unevenly, invite
BYD authorized service station to check the
wheel alignment condition.

The tire has been balanced before leaving
factory, but before the tire is worn down,
sometimes, maybe need to rebalance the tire.
If you feel a consistent vibration while
driving, you should invite BYD authorized
service station to check the tires. If some
tire ever has been repaired, make sure to
rebalance the tire.

When you have new tires installed, make
sure they are balanced. This increases riding
comfort and tire life. Your vehicle‘s original
tires have the dynamic balance or ―idle‖

balance done before leaving factory. You
had better let the installer perform a
dynamic balance

.

Notice

Improper wheel balancer will damage
your vehicle‘s aluminum alloy wheel.
So use only BYD AUTO balancer to
keep balance.

BYD AUTO F6 OWNER’S MANUAL

124

Tire transposition

To help increase tire life and wear more
evenly, change the position of tires every
10,000 km. You should move the tires to the
position showing above every changing
position.

The picture above shows how to change
vehicle‘s tire position which doesn‘t have
standard spare tires.

When you buy and replace tires, you may
find some tires are ―directional‖, this means
this kind tire is designed into only one
direction changing. If you use directional
tires, they can only exchange front and rear
wheels when changing tire position.

If you use standard spare tires when
changing position, please refer to the right
picture.
If the spare rim is different to the using tire
rim, advice not to change the position.

BYD AUTO F6 OWNER’S MANUAL

125

Replace tire and wheel
The vehicle‘s original tires is chose to
furthest play the vehicle performance, they
can provide the best combination of
handling, tire life and riding comfort at the
same time. You should choose radial tires to
exchange which have same size, load range,
speed rating, and maximum cold tire
pressure (marked on the side of tire).
Mixing using radial and bias-ply tires can
reduce braking ability, driving force
(adhesive force) and steering accuracy.

Installing improper tires on your vehicle can
affect your vehicle‘s handling agility and
stability. This can cause a crash in which
you can be seriously hurt or killed.

It is best to replace all four tires at the same
time. If that is not possible or necessary,
replace the two front tires or rear tires as a
pair. Replacing just one tire can seriously
affect your vehicle handling.

ABS is working by comparing wheel speed.
So when replacing the tires, you should use
the tire whose size is same to vehicle‘s
original wheel. The size and structure of tire
can affect the speed, and cause system‘s

action in coordination.

If you need to replace wheel, make sure that
the wheel‘s specifications match those of
the original wheels. Replacement new
wheels are available at BYD authorized
service station. Before replacing the tires,
you should refer to BYD authorized service
station.

Winter tire
Because the summer tire‘s applicability is
limited, advice to use winter tires (M+S tire)
on ice and snow pavement. If install the

M+S tires, all wheels should be installed to
insure safety driving. You can only use tire
with same brand and same form. When
buying, you should pay attention to tire‘s
size, load range and speed rating.

Install the winter tires according to the
marks on the register card. When installing
tires according to tire regulations of EEC, if
vehicle original designed speed exceeds the
Max. permissible speed of winter tire, you
should stick a label to one position which
the driver can be easy to see, writing the
MAX. permissible speed of winter tire. The
tire dealer can supply this kind of labels. If
you have questions, please refer to BYD
authorized service station.

Tire chains

Snow tire chains are used only for
emergency or in the special area where they
are required by driving condition or local
laws. Install them only on the front wheel.
You need more careful when you drive your
vehicle with snow tire chains on ice and
snow pavement. Comparing with the
high-grade winter tire without chains, the
forecasting and handling of the tire with

BYD AUTO F6 OWNER’S MANUAL

126

chains is quite worse. Some chains may also
damage vehicle‘s tire, wheel, suspension
and body. You should choose with chains to
make enough free space between tire and
other parts in the wheel cowl. Look over
and read parts assembly graph and other
instructions of chain factory carefully.
Before you want to buy chains and install
them on the vehicle, you should refer to
BYD authorized service station.

After installing the chains, the speed driving
on the ice and snow pavement should be
below 30 km/h. To furthest lighten the
werainf of tires and chains, you should
avoid driving with the tire installed chains
on the pavement without ice and snow.
