Tire Inflation Pressure - Mercedes-Benz 300SDL-TURBO 126 D 1986 Owner's Manual

11. Install spare wheel on wheel hub.
Insert wheel bolts and tighten
them slightly.
To avoid paint damage, place
wheel flat against hub and hold it
there while installing first wheel
bolt. Unscrew the alignment stud
to install the last wheel bolt.
12. Lower car, remove jack.
13. Engage jack tube cover hooks on
top and snap bottom into place.
14. Tighten the five bolts evenly,
always skipping one, until all bolts
are tight. Observe a tightening
torque of 110 Nm (80 Ib-ft).
15. C orrect tire pressure.
Important!
Retighten wheel mounting bolts after
approx. 800 km (500 miles). Observe
a tightening torque of 110 Nm
(80 Ib-ft).

Tire Inflation Pressure

A table (see fuel filler flap or last
page) lists the tire inflation pressures
specified fo r sum m er and w inter tires
as well as fo r the varying operating
conditions.
Important!
Tire pressure differs by approx.
0.1 bar (1.5 psi) per 10° C (18° F) of
air tem perature change. Keep this in
mind when checking tire pressure
inside a garage — especially in the
w inter.
Example:
If garage tem perature =
approx. + 2 0 ° C ( + 68° F) and,
ambient tem perature =
approx. 0° C (+ 3 2 ° F) then the
adjusted air pressure = specified air
pressure + 0 .2 bar ( + 3 psi).
Tire pressures listed fo r light loads
are minimum values offering high driv­
ing com fort. Increased inflation pres­
sures fo r heavy loads produce favora­
ble handling characteristics with ligh­
ter loads and are perfectly perm issi­
ble. The ride of the vehicle, however,
will become somewhat 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 pres­
sure has dropped below the pressure
listed in the table and the respective
operating conditions are taken into
consideration.
