'xIf the vehicle has not moved again for at least2 hours after a trip.1.Determine, refer to page 240, the intended
tire inflation pressure levels for the mounted
tires.2.Check the tire inflation pressure in all four
tires, using a pressure gage, for example.3.Correct the tire inflation pressure if the curj

Recommendation

Manufacture
date You can find the manufacture date of the tire onthe tire's sidewall.DesignationManufacture

TractionThe traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfaj
ces of asphalt and concrete. A tire marked C may have poor traction performance.
The traction grade assigned to this tire is based on straight-ahead braking traction tests, and
does not include acceleration, cornering, hydroj planing, or peak traction characteristics.
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the
tire to degenerate and reduce tire life, and excesj
sive temperature can lead to sudden tire failure.
The grade C corresponds to a level of performj
ance which all passenger vehicle tires must meet
under the Federal Motor Vehicle Safety Standard
No. 109. Grades Band A represent higher levels of performance on the laboratory test wheel thanthe minimum required by law.
WARNING
The temperature grade for this tire is estabj lished for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in comj bination, can cause heat buildup and possibletire failure.
RSC
m
Run-flat
tires
Run-flat tires, refer to page 251, are labeled with
a circular symbol containing the letters RSC marked on the sidewall.
M+S
Winter and all-season tires with better cold weather performance than summer tires.
Tire
tread
Summer
tiresDo not drive with a tire tread of less than
0.12 in/3 mm, otherwise there is an increased
risk of hydroplaning.
Winter
tires Do not drive with a tire tread of less than
0.16 in/4 mm, as such tires are less suitable for winter operation.
Minimum
tread
depth
Wear indicators are distributed around the tire's
circumference and have the legally required minj imum height of 0.063 inches/1.6 mm.
The positions of the wear indicators are marked on the tire sidewall with TWI, Tread Wear Indicaj
tor.
Tire
damage
General
information Inspect your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.
Driving over rough or damaged road surfaces, as
well as debris, curbs and other obstacles can
Seite 248MOBILITYWheels
and
tires248
Online Edition for Part no. 01402988494 - II/18

cause serious damage to wheels, tires and susj
pension parts. This is more likely to occur with low-profile tires, which provide less cushioning
between the wheel and the road. Be careful to
avoid road hazards and reduce your speed, esj
pecially if your vehicle is equipped with low-proj file tires.
Indications of tire damage or other vehicle malj
functions:'xUnusual vibrations.'xUnusual tire or running noises.'xUnusual handling such as a strong tendency
to pull to the left or right.
Damage can be caused by the following situaj
tions, for instance:
'xDriving over curbs.'xRoad damage.'xTire inflation pressure too low.'xVehicle overloading.'xIncorrect tire storage.
Safety
information
WARNING
Damaged tires can lose tire inflation pressure,
which can lead to loss of vehicle control. There is a risk of an accident. If tire damage is susj
pected while driving, immediately reduce speed
and stop. Have wheels and tires checked. For
this purpose, drive carefully to the nearest dealj erss service center or another qualified service
center or repair shop. Have vehicle towed or
transported as needed. Do not repair damaged
tires, but have them replaced.
WARNING
Tires can become damaged by driving over obj
stacles, e.g., curbs or road damage, at high
speed. Larger wheels have a smaller tire cross- section. The smaller the tire cross-section, the
higher the risk of tire damage. There is a danj
ger of accidents and property damage. If possij
ble, drive around obstacles, or drive over them
slowly and carefully.
Changing
wheels
and
tires
Mounting
Have mounting and wheel balancing carried out
by a dealerss service center or another qualified
service center or repair shop.
Wheel
and
tire
combinationGeneral
information
You can ask the dealerss service center or anj
other qualified service center or repair shop about the correct wheel/tire combination andwheel rim versions for the vehicle.
Safety
information
WARNING
Wheels and tires which are not suitable for your vehicle can damage parts of the vehicle, for inj stance due to contact with the body due to toljerances despite the same official size rating.
There is a risk of an accident. The manufacj turer of your vehicle strongly suggests that you
use wheels and tires that have been recomj mended by the vehicle manufacturer for your
vehicle type.
WARNING
Incorrect wheel/tire combinations will have a
negative impact on the vehicle's handling and
on the function of a variety of systems, such as
ABS or DSC. There is a risk of an accident. To
maintain good handling and vehicle response, use only tires with a single tread configuration
from a single manufacturer. The manufacturer
of the vehicle recommends that you use
Seite 249Wheels
and
tiresMOBILITY249
Online Edition for Part no. 01402988494 - II/18

wheels and tires that have been recommended
by the vehicle manufacturer for your vehicle type. Following tire damage, have the original
wheel/tire combination remounted on the vehij
cle as soon as possible.
Recommended
tire
brands
For each tire size, the manufacturer of the vehij cle recommends certain tire brands. The tire
brands can be identified by a star on the tire
sidewall.
New
tires Tire traction is not optimal due to manufacturing
circumstances when tires are brand-new; they achieve their full traction potential after a break-intime.
Drive conservatively for the first
200 miles/300 km.
Retreaded
tires
WARNING
Retreaded tires can have different tire casing
structures. With advanced age the service life
can be limited. There is a risk of an accident.
The manufacturer of your vehicle does not recj
ommend the use of retreaded tires.
The manufacturer of your vehicle does not recj
ommend the use of retreaded tires.
Winter
tires
Winter tires are recommended for operating onwinter roads.
Although so-called all-season M+S tires provide better winter traction than summer tires, they
usually do not provide the same level of performj ance as winter tires.
Maximum
speed
of
winter
tires If the maximum speed of the vehicle is higherthan the permissible speed for the winter tires,
then attach a label showing the permissible maxij mum speed in the field of view. The label is availjable from a dealerss service center or anotherqualified service center or repair shop.
With winter tires mounted, observe and do not
exceed the permissible maximum speed.
Run-flat
tires
If you are already using run-flat tires, for your own
safety you should replace them only with the same kind. No spare tire is available in the caseof a flat tire. Further information is available froma dealerss service center or another qualifiedservice center or repair shop.
Rotating
wheels
between
axles
Different wear patterns can occur on the front
and rear axles depending on individual driving
conditions. The tires can be rotated in pairs bej
tween the axles to achieve even wear. Further inj formation is available from a dealerss service cenjter or another qualified service center or repairshop. After rotating, check the tire pressure and
correct, if needed.
Rotating the tires between the axes is not perj
missible on vehicles with different tire sizes or
rim sizes on the front and rear axles.Seite 250MOBILITYWheels
