Mercedes Benz 2004 c 320 Manual De Usuario

Tire pressure changes by approx. 1.5 psi 
(0.1 bar) per 18°F (10°C) of air tempera-
ture change. Keep this in mind when 
checking tire pressure where the tempera-
ture is different from the outside tempera-
ture.

Tire temperature and tire pressure are also 
increased while driving, depending on the 
driving speed and the tire load.

Check the spare tire periodically for condi-
tion and inflation. Spare tires will age and 
become worn over time even if never used, 
and thus should be inspected and replaced 
when necessary.

On vehicles with the same wheel size all 
around, wheels can be rotated every 3000 
to 6000 miles (5000 to 10 000 km), or 
sooner if necessary, according to the 
degree of tire wear. The same direction of 
tire rotation must be retained.

Rotate the wheels before the characteris-
tic tire wear pattern becomes visible 
(shoulder wear on front wheels and tread 
center wear on rear wheels).

Thoroughly clean the inner side of the 
wheels after each rotation. Check and 
ensure proper tire inflation pressure.

G

Follow recommended inflation pressures.

Do not overinflate tires. Overinflated tires 
can result in sudden deflation (blowout) 
because they are more likely to become 
punctured or damaged by road debris, 
potholes, etc.

Do not underinflate tires. Underinflated tires 
wear unevenly, adversely affect handling 
and fuel economy, and are more likely to fail 
from being overheated.

Do not overload the tires by exceeding the 
specified vehicle capacity weight (as indi-
cated by the label on the pillar in the driver’s 
door opening). Overloading the tires can 
overheat them, possibly causing a blowout.

G

Rotate front and rear wheels only if they are 
of the same size.

G

Have the tightening torque checked after 
changing a wheel. Wheels could become 
loose if not tightened with a torque of 
80 lb-ft (110 Nm).

Only use genuine Mercedes-Benz wheel 
bolts specified for your vehicle's rims.
