wheel alignment VOLVO V70 2002 Owners Manual

The tires have wear indicator strips running across or parallel to the tread. When approx. 1/16" (1.6 mm) is left on the
tread, these strips become visible and indicate that the tire should be replaced.
Tires with less than 1/16" (1.6 mm) tread have very poor grip in rain or snow.
To improve tire economy:
Maintain correct tire pressure. See the tire pressure label on the inside of the fuel filler door.
Drive smoothly: avoid fast starts, hard braking and tire screeching.
Tire wear increases with speed.
Correct front wheel alignment is very important.
Unbalanced wheels impair tire economy and driving comfort.
Volvo does not recommend rotating the tires. However, if tires are rotated, they must be kept on the same side of the
car so that they revolve in the same direction as before rotation.
Hitting curbs or potholes can damage the tires and/or wheels permanently.
Flat spots
All tires become warm during use. After cooling, when the vehicle is parked, the tires have a tendency to distort
slightly, forming flat spots. These flat spots can cause vibrations similar to the vibrations caused by unbalanced wheels.
They do, however, disappear when the tire warms up. The degree to which flat spots form depends on the type of cord
used in the tire. Remember that, in cold weather, it takes longer for the tire to warm up and consequently longer for the
flat spot to disappear.
CAUTION: Cars equipped with All Wheel Drive
The car must not be driven with wheels of different dimensions/ specifications or with a spare tire other than the one
that came with the car. The use of different size wheels can seriously damage your car's transmission.
Driving with the temporary spare tire at speeds above 50 mph (80 km/h) can reduce the service life of transmission
components. Do not drive farther than 50 miles (80 km) on a temporary spare tire.
When one or more tires is replaced, the new tire(s) should be mounted on the front wheels. The tires with the least
amount of tread should be mounted on the rear wheels.

Types of Tires
Always drive on tires of identical brand, size, construction (radial), tread pattern, load-, speed-, traction-, temperature-,
and treadwear rating. Never drive on mixed tires, except for brief periods when the temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and inflation pressures are shown on the tire
pressure label located inside the fuel filler door.
CAUTION:
Failure to always drive on properly inflated, identical tires of correct dimensions may result in a circumference
difference between tires on the front and rear axles. This will cause excessive tire wear and may damage the
transmission and all-wheel-drive system.
