Tire Inflation Pressure - Mercedes-Benz C-class Operator's Manual

Notes:
Before storing the jack, it should be fully collapsed, with
handle folded in.
For proper storage of vehicle jack see page 304.
Warning!
Always replace wheel bolts that are damaged or
rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be repaired
immediately.
Incorrect mounting bolts or improperly tightened
mounting bolts can cause the wheel to come off.
This could cause an accident. Be sure to use the
correct mounting bolts.

Tire inflation pressure

A table (see fuel filler flap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approximately 1.5 psi (0.1 bar)
per 18 ° F (10 ° C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage –
especially in the winter.
Example:
If garage temperature = approximately +68 ° F (+20 ° C)
and ambient temperature = approximately +32 ° F (0 ° C)
then the adjusted air pressure = specified air pressure
+3 psi (+0.2 bar).
Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.
Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
