Volvo XC90: Wheels and tires / Tire direction of rotation
Tires with tread designed to roll in only one direction are marked with an
arrow on the sidewall.

The arrow shows the tire's direction of rotation.
- The tire should maintain the same direction of rotation throughout its service
life.
- Tires should only be moved between the front and back, never from right
to left or vice versa.
- Incorrectly mounted tires impair the vehicle's braking properties and ability
to force aside rain, snow and slush.
- The tires with the most tread should always be mounted on the rear wheels
to help reduce the risk of skidding.
NOTE
Use tires of the same type, dimensions and make (manufacturer) on each
axle.
The function of the tires is to carry loads, provide traction on r oad
surfaces, reduce vibrations and protect the wheels from wear. The tires significantly
influence the vehicle's driving characteristics...
The tread wear indicator shows the status of the tire's tread.
The tread wear indicator is a narrow elevated strip running across the tire's
longitudinal tread grooves...
