Tyres' Rotation Direction - Volvo XC 90 Owner's Manual

Tyres' rotation direction

Tyres with a tread pattern which are designed to
only turn in one direction have the direction of
rotation marked with an arrow.
The arrow shows the tyre's direction of rotation.
The tyre must always rotate in the same direction
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 tyres are fitted incorrectly, the car's braking
characteristics and capacity to force rain 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).
NOTE
Make sure that both pairs of wheels have the
same type and dimension, and also the same
make.

Tread wear indicators on the tyres
Tread wear indicators show the status of the
tyre's tread depth.
A tread wear indicator is a narrow elevation
across the longitudinal grooves of the tyre's tread
pattern. On the side of the tyre are the letters
TWI (Tread Wear Indicator). When the tyre's tread
depth is down to 1.6 mm, the tread will be level in
height with the tread wear indicators. Change to
new tyres as soon as possible. Remember that
tyres with little tread depth provide very poor grip
in rain and snow.
