All passenger car tires must conform to the stat-
utory safety requirements in addition to these
grades.
iThe actual values for tires are vehicle-spe-
cific and may deviate from the values in the
illustration.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified U.S.
government course. For example, a tire graded
150 would wear one and one-half times as well
on the government course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices
and differences in road characteristics and cli-
mate.
Traction
GWARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction char-
acteristics.
!Avoid wheelspin. This can lead to damage to
the drive train.
The 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 meas-
ured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. A tire marked C may have poor traction
performance.
The safe speed on a wet, snow covered or icy
road is always lower than on dry road surfaces.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Mercedes-Benz recommends a minimum tread
depth of ãin (4 mm) on all four winter tires.
Observe the legally required minimum tire tread
depth (
Ypage 352). Winter tires can reduce the
braking distance on snow-covered surfaces in
comparison with summer tires. The braking dis-
tance is still much further than on surfaces that are not icy or covered with snow. Take appro-
priate care when driving.
Further information on winter tires (M+S
tires)
(
Ypage 353).
Temperature
GWARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately or
in combination, can cause excessive heat
build-up and possible tire failure.
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. Sus-
tained high temperature can cause the material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A represent
higher levels of performance on the laboratory
test wheel than the minimum required by law.

only use wheel bolts which have been approved
for Mercedes-Benz vehicles and the respective
wheel.
!Always use wheel bolts;to mount the
"Minispare" emergency spare wheel. Using
other wheel bolts to mount the "Minispare"
emergency spare wheel could damage the
brake system.

XSlide the wheel to be mounted onto the align-
ment bolt and push it on.
XTighten the wheel bolts until they are finger-
tight.
XUnscrew the alignment bolt.
XTighten the last wheel bolt until it is finger-
tight.
XMercedes-AMG vehicles with a collapsi-
ble spare wheel: inflate the collapsible spare
wheel (
Ypage 379).
Only then lower the vehicle.
Lowering the vehicle
GWARNING
The wheels could work loose if the wheel nuts and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
!Mercedes-AMG vehicles with a collapsi-
ble spare wheel: before lowering the vehicle,
inflate the collapsible spare wheel with the
tire inflation compressor. The wheel rim could
otherwise be damaged.
XPlace the ratchet wrench onto the hexagon
nut of the jack so that the letters ABare visi-
ble.
XTurn the ratchet wrench until the vehicle is
once again standing firmly on the ground.
XPlace the jack to one side.
XTighten the wheel bolts evenly in a crosswise pattern in the sequence indicated (: toA).
The tightening torque must be 110 lb-ft
(150 Nm).
XTurn the jack back to its initial position.
XStow the jack and the rest of the tire-change
tool kit in the stowage well under the cargo
compartment floor again.
XCheck the tire pressure of the newly mounted
wheel and adjust it if necessary.
Observe the recommended tire pressure
(
Ypage 354).
When you are driving with the collapsible spare
wheel mounted, the tire pressure loss warning
system or the tire pressure monitor cannot func-
tion reliably. Only restart the tire pressure loss
warning system or tire pressure monitor when

Inflating the collapsible spare wheel
(Ypage 379).
Take the following steps to stow a used collaps- ible spare wheel. Otherwise, it will not fit into the
spare wheel well. Mercedes-Benz recommends
that you have this work performed at a qualified
specialist workshop, e.g. at an authorized
Mercedes-Benz Center.
Stowing the emergency spare wheel
XUnscrew the valve cap from the valve.
XIf possible, unscrew the valve insert from the
valve and release the air.
iFully deflating the tires can take a few
minutes.
XScrew the valve insert back into the valve.
XScrew the valve cap back on.
XLay collapsible spare wheel :in the emer-
gency spare wheel well.
XScrew in retaining screw ;clockwise in the
collapsible spare wheel to the stop.
XSwing the cargo compartment floor down
(Ypage 303).

On Mercedes-AMG vehicles with a Bang & Oluf-
sen sound system, the collapsible spare wheel is
packed in an emergency spare wheel bag. The
