Tire rotation
Summer and winter tires
When switching between summer and winter tires, mark the tires to indicate where they were mounted on the car,
e.g. LF = left front, RR = right rear
Tires with tread designed to roll in only one direction are marked with an arrow on the sidewall.
Incorrectly mounted tires impair the car's braking properties and ability to force aside rain, snow and slush.
The tires with the most tread should always be at the rear (to reduce the risk of skidding).
Contact a Volvo workshop if you are unsure about the tread depth.
