Tire Inflation Pressure - Mercedes-Benz SL Operator's Manual

Warning!
Do not drive the vehicle while the wheel change
switch is activated since the vehicle suspension
will not function properly.
Warning!
The spare wheel rim is for temporary use only. Use
for over a total of 12 000 miles (20 000 km) may
cause wheel rim failure leading to an accident and
possible injuries.
Vehicles with Sport Package:
The dimensions of the spare wheel are different
from those of road wheels. As a result, the vehicle
handling characteristics change when driving with
a mounted spare wheel.
The spare wheel should only be used temporarily,
and replaced with a regular road wheel as quickly
as possible.

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 approx. 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 = approx. +68°F (+20°C) and
ambient temperature = approx. +32°F (0°C) then the
adjusted air pressure = specified air pressure +3psi
(+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
