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 - espe­
cially in the winter.
Example:
If garage temperature =
approx. + 6 8 °F (+ 20°C) and
ambient temperature =
approx. + 3 2 °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.
102
Increased inflation pressures for
heavy loads produce favorable
handling characteristics with
lighter loads and are perfectly
permissible. The ride of the ve­
hicle, however, will become
somewhat harder.
Tire temperature and pressure
increase with the vehicle speed.
Tire pressure should therefore
only be corrected on cold tires.
Correct tire pressure in warm tires
only if pressure has dropped be­
low 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 damage 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 damage.
W arning!
Do not overinflate tires.
Overinflating tires can result
in sudden deflation (blowout)
because they are more likely
to become punctured or
damaged by road debris,
potholes etc.. Follow recom­
mended inflation pressures.
Do not overload the tires by
exceeding the specified
vehicle capacity weight (as
indicated by the label on the
driver's door latch post).
Overloading the tires can
overheat them, possibly
causing a blowout.
