Snow Tires - Volvo S90 2019 Owner's Manual

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.
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.
NOTE
Contact a Volvo dealer for advice on the
best choice of rims and tires.
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.
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
Regulations regarding the use of studded
tires vary from country to country.
WHEELS AND TIRES
Tread depth
Road conditions with ice, slush and low tem-
peratures place considerably higher demands
on tires than summer conditions. Volvo there-
fore recommends not driving on snow tires
that have a tread depth of less than 4 mm
(0.15 inch).
