See your authorized Mercedes-Benz Light Truck 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 and rear tires should be replaced in sets. 
Furthermore – in the event of tire replacement – the 
optional regular size spare wheel should be used on the 
rear axle. Rims and tires must be of the correct size and 
type. For dimensions, see technical data on page 288.
We recommend that you break in new tires for 
approximately 60 miles (100 km) at moderate speed.
It is imperative that the wheel mounting bolts be 
fastened to a tightening torq ue of 110 ft.lb. (150 Nm) 
whenever wheels are mounted.
For rim and tire specifications, refer to technical data on 
page 288.
Wa r n i n g !
Do not mix different tire construction types (i.e. 
radial, bias, bias-belted) on your vehicle because 
handling may be adversely affected and may result 
in loss of control.
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.
