Summer and winter wheels
The arrow shows the tyre’s direction of rotation
When summer and winter wheels are
changed they should be marked with which
side of the car they were mounted on, for ex-
ample L for left and R for right. Tyres with
tread patterns which are designed to only ro-
tate in one direction have the direction of ro-
tation marked with an arrow on the tyre.
The tyre should always rotate in the same di-
rection throughout its lifespan. Tyres should
only be switched between front and rear po-
sitions, never between left and right-hand
sides, or vice versa. If the tyre is mounted in-
correctly, the car’s braking characteristics
and capacity to force rain, snow and slush
out of the way are adversely affected.
Tyres with the greatest tread depth should al-
ways be fitted to the rear of the car (to de-
crease the risk of skidding).
Wheels should be stored lying down or hang-
ing up, and not standing up.
Contact an authorised Volvo workshop if you
are uncertain about tread depth.
