information.
See your authorized Mercedes-Benz Center for 
information on tested and recommended rims and tires 
for summer and winter operation. They can also offer 
advice concerning tire service and purchase.
Tire replacement
Front tires should be replaced in sets. Rims and tires 
must be of the correct size and type. For dimensions, 
see “Technical Data” (page 314).
We recommend that you break in new tires for approx. 
60 miles (100 km) at moderate speed.It is imperative that the wheel mounting bolts be 
fastened to a tightening torque of 80 ft.lb. (110 Nm) 
whenever wheels are mounted.
For rim and tire specifications, refer to “Technical Data” 
(page 314).
Wa r n i n g !
Worn, old tires can cause accidents. If the tire tread 
is badly worn, or if the tires have sustained 
damage, replace them.When replacing rims, use only genuine 
Mercedes-Benz wheel bolts specified for the 
particular rim type. Failure to do so can result in 
the bolts loosening and possibly an accident.

(aggregate of all uses) may cause wheel rim failure 
leading to an accident and possible injuries.CLK 320 with Sport Package, CLK 430, 
CLK 55 AMG:The dimensions of the spare wheel are different 
from those of the road wheels for the rear axle 
(CLK 320 with Sport Package: The dimensions of 
the spare wheel are different from those of the road 
wheels). As a result, the vehicle handling 
characteristics change when driving with a spare
