Mercedes Benz 2009 M-Class User Manual

왔

See an 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.

앫

Only use sets of tires and rims of the 
same type and make.

앫

Tires must be of the correct size for the 
rim.

앫

Break in new tires for approximately 
60 miles (100 km) at moderate 
speeds.

앫

Regularly check the tires and rims for 
damage. Dented or bent rims can 
cause tire inflation pressure loss or 
damage to the tire beads.

앫

If vehicle is heavily loaded, check tire 
inflation pressure and correct as 
required.

앫

Do not allow your tires to wear down 
too far. Adhesion properties on wet 
roads are sharply reduced at tread 
depths under 

1

/

8

in (3 mm).

앫

When replacing individual tires, you 
should mount new tires on the front 
wheels first (on vehicles with 
same-sized wheels all around).

G

Replace rims or tires with the same designa-

tion, manufacturer and type as shown on the 

original part. See an authorized 

Mercedes-Benz Light Truck Center for fur-

ther information. If incorrectly sized rims 

and tires are mounted:

앫

The wheel brakes or suspension 
components can be damaged.

앫

The operating clearance of the wheels 
and the tires may no longer be correct.

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, only use 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.

Retreaded tires are not tested or recom-

mended by Mercedes-Benz, since previous 

damage cannot always be recognized on re-

treads. The operating safety of the vehicle 

cannot be assured when such tires are used.
