Tire Inflation Pressure
A table (see fuel filler flap) lists the
tire inflation pressures specified for
M ercedes-Benz recom m ended
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 tem perature change. Keep this
in mind when checking tire
pressure inside a garage - espe­
cially in the winter.
Example:
If garage tem perature =
approx. +68°F (+20°C) and
am bient tem perature =
approx. +32°F (0°C) then the
adjusted air pressure = specified
air pressure +3 psi (+0.2 bar).
Tire pressures listed fo r light loads
are m inim um values offering high
driving com fort. Increased inflation
pressures for heavy loads produce
favorable handling characteristics
with lighter loads and are perfectly
permissible. The ride of the v e ­
hicle, however, will becom e
som ew hat harder.
Tire tem perature and pressure
increase with the vehicle speed.
Tire pressure should therefore only
be corrected on cold tires. C orrect
tire pressure in warm tires only if
pressure has dropped below the
pressure listed in the table and the
respective operating conditions are
taken into consideration.
An underinflated tire due to a slow
leak (e.g. due to a nail in the tire)
may cause dam age such as tread
separation, bulging etc.. Regular
tire pressure checks (including the
spare tire) at intervals of no more
than 14 days are therefore
essential.
If a tire constantly loses air, it
should be inspected for dam age.
W arning!
Do not o verin flate tires.
O verinflating tires can result in
sudden deflation (blow out)
because they are m ore likely
to becom e punctured or
dam aged by road debris,
potholes etc.. Follow
recom m ended inflation
pressures.
Do not overload the tires by
exceeding the specified
vehicle capacity w eight (as
indicated by the label on the
d riv e r's d oor latch post).
O verloading the tires can
overheat them , possibly
causing a blowout.
