run flat 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.
