Tire Inflation Pressure - Mercedes-Benz 300 SE 1993 Owner's Manual

Tire Inflation Pressure

A table (see fuel fille r flap) lists the
tire inflation pressures specified
for M ercedes-B enz recom m ended
tires as well as for the varying
operating conditions.
Im portant!
Tire pressure changes by approx.
1.5 psi (0.1 bar) per 1 8°F (1 0 °C )
of air tem perature change. Keep
this in m ind when checking tire
pressure inside a garage - espe­
cially in the w inter.
Exam ple:
If garage tem perature =
approx. + 6 8 °F ( + 2 0 °C ) and
am bient tem perature =
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 m inim um values offering high
d riving com fort.

Increased inflation pressures for
heavy loads produce favorable
h andling characte ristics with
lighter loads and are perfectly
perm issible. The ride of the ve­
hicle, how ever, w ill becom e
som ew hat harder.
Tire tem perature and pressure
increase with the vehicle speed.
T ire pressure should therefore
only be corrected on cold tires.
C orrect tire pressure in w arm tires
only if pressure has dropped be­
low the pressure listed in the table
and the respective operating
co nd itio ns are taken into
consideration.
An underinflated tire due to a slow
leak (e.g. due to a nail in the tire)
m ay cause dam age such as tread
separation, bulging etc.. R egular
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.
Warning!
Do not overinflate tires.
O verinflating tire s 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 eig h t (as
indicated by the label on the
d river's door latch post).
Overloading the tires can
o verheat them , possibly
causing a blowout.
