Wheels And Tires - Volvo 164 1973 Owner's Manual

WHEELS AND TIRES
General
The car is fitted with pressed steel wheels
with wheel cap which is bolted to the hub
cap.
If possible, radial tires should always be
used, even in the wintertime.
The wheels should always be used on the
same side throughout their use. This is
particularly important for studded snow
tires, otherwise it can happen that the
studs loosen.
Studded snow tires should also have a
running-in period of between 300-600
miles (500-1000 km). During this period
try to avoid driving hard round bends and
at high speeds, also hefty braking and ac-
celeration.
Snow chains can be used on all the car's
four wheels providing that the chains are
fine-linked and do not project so much
from the tire that they can chafe against
the brake caliper or other components.
Rapid links must not be fitted since the
space between the brake calipers and
wheel rims does not permit this.
Check tire wear pattern
Check the tires at regular intervals for
damage and abnormal wear, also for par-
ticles which can fasten in the tread . Have
the wheels balanced if necessary. Poorly
balanced wheels will rapidly increase the
wear on tires as weil as make for poor trav-
elling comfort and driving characteristics.
The tires have a so-called "wear indicator"
in the form of a number of narrow strips
running across or paralIei to the tread.
When about
1116"
(1.5 mm) is left on the
tread, these strips show up and warn the
ear owner in good time that the tire is
showi ng sig ns of wear.
SERVICING
Check tire pressure
Make a habit of checking the pressure in
the tires regularly. The simplest way to do
this is to check the pressure at a service
station while filling up with fuel. See page
67 for the correct tire pressure. Do not for-
get the spare wheel when checking the
tire pressure.
During driving, the temperature of the tires
rises and also the tire pressure in relation
to the speed of the vehicle and its load.
Normally the tire pressure should only be
checked when the tires are cold. When the
tires are warm, a change in pressure
should take place only when air must be
pumped into the tires.
Excessively low tire pressure is one of the
most common reasons for tire wear. Tires
which are insufficiently inflated also result
in difficult steering and high fuel consump-
tion . Too high tire pressure tends to make
for poor travelling comfort.
Be careful when parking the ear next to
the pavement not to damage the tires
against the pavement kerb.
