Summer and winter wheels
The arrow shows the tyre's direction of rotation.
When summer and winter wheels are changed
the wheels should be marked with which side
of the car they were mounted on, for example
V for left and H for right. Tyres with a tread pat-
tern which are designed to only turn in one
direction have the direction of rotation marked
with an arrow.
The tyre must always rotate in the same direc-
tion throughout its lifespan. Tyres should only
be switched between front and rear positions,
never between left and right-hand sides, or
vice versa.
If the tyre is mounted incorrectly, 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
always be fitted to the rear of the car (to
decrease the risk of skidding).
Contact an authorised Volvo workshop if you
are uncertain about tread depth.
