WHEELS AND TIRES

Stowing a flat tire
1. Screw the spare tire's retaining bolt back
on.
CAUTION
Do not attempt to unscrew the lower part
of the retaining bolt if it is attached to the
body, as this could cause it to break.
If the retaining bolt becomes dislodged
from its lower attachment point in the
body under the spare tire, replace it in the
hole and turn clockwise to secure it again.
WARNING
On vehicles with 48 V batteries, the bolt is
attached to the battery box instead of the
body. If the lower part of the retaining bolt
is not dislodged when the spare tire is
taken out, it should be removed to help
prevent injury when the flat tire is replaced.
2. Put the tools back in their correct posi-
tions in the foam block.
3. Then lower the trunk/cargo compartment
floor and place the punctured tire in the
trunk/cargo compartment.

Snow tires
Snow tires are designed for winter driving
conditions.
Volvo recommends snow tires with specific
dimensions. The tire dimensions vary depend-
ing on engine type. When driving with snow
tires, the correct type of tires must be moun-
ted on all four wheels.
Tips for changing snow tires
When switching between regular tires and
snow tires, mark the tires according to which
side they were mounted on, e.g. L for left and
R for right.
Contact a Volvo retailer for assistance deter-
mining the most suitable rims and tires.
Studded tires
Studded tires should be broken in by driving
500–1000 km (300–600 miles) slowly and
gently to help the studs settle properly in the
tires. This gives the tire, and especially the
studs, a longer service life.
NOTE
Legal requirements concerning the use of
studded tires may vary. Always follow local
laws and regulations.
Tread depth
Road conditions with ice, slush and low tem-
peratures place considerably higher demands
