Tyres - tread wear indicators

A tread wear indicator shows the status of the
tyre's tread.
Tread wear indicators.
Tread wear indicators are narrow treadless
bands across the width of the tread. 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 depth 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.

Wheel bolts

Wheel bolts are used to fasten the wheels at
the hubs and are available in different ver-
sions.
IMPORTANT
The wheel bolts must be tightened to 140
Nm. Overtightening can damage the nuts
and the bolts.
Only use rims that are tested and approved
by Volvo and which are Volvo genuine acces-
sories. Check the torque with a torque
wrench.
Locking wheel bolts*
Locking wheel bolts* can be used on both
aluminium and steel rims. Under the cargo
area floor there is space for the sleeve for the
lockable wheel bolts.
