Tread wear indicatorThe tread wear indicator shows the status of the tire's tread.
The tread wear indicator is a narrow elevated strip running across the tire's longitudinaltread grooves. The letters TWI (Tread WearIndicator) are visible on the side of the tire.When approximately 1.6 mm (1/16 inch) is lefton the tread, the tread will be at the sameheight as the tread wear indicator. Replace thetire as soon as possible. Tires with low treadoffer very poor traction in rain or snow.

Tire terminology
The following is a glossary of tire-related terms.
The tire suppliers may have additional mark- ings, notes or warnings such as standard load,radial tubeless, etc.
Tire information placard
: A placard
showing the OE (Original Equipment) tiresizes, recommended inflation pressure,and the maximum weight the vehicle cancarry.
Tire Identification Number (TIN)
: A num-
ber on the sidewall of each tire providinginformation about the tire brand and man-ufacturing plant, tire size and date of man-ufacture.
Inflation pressure
: A measure of the
amount of air in a tire.
Standard load
: A class of P-metric or
Metric tires designed to carry a maximumload at 35 psi [37 psi (2.5 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetires load carrying capability.
Extra load
: A class of P-metric or Metric
tires designed to carry a heavier maximumload at 41 psi [43 psi (2.9 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetire's load carrying capability.
kPa
: Kilopascal, a metric unit of air pres-
sure.
PSI
: Pounds per square inch, a standard
unit of air pressure.
B-pillar
: The structural member at the
side of the vehicle behind the front door.
Bead area of the tire
: Area of the tire next
to the rim.
Sidewall of the tire
: Area between the
bead area and the tread.
Tread area of the tire
: Area of the perime-
ter of the tire that contacts the road whenmounted on the vehicle.
Rim
: The metal support (wheel) for a tire
or a tire and tube assembly upon whichthe tire beads are seated.
Maximum load rating
: a figure indicating
the maximum load in pounds and kilo-grams that can be carried by the tire. Thisrating is established by the tire manufac-turer.
Maximum permissible inflationpressure
: the greatest amount of air pres-
sure that should ever be put in the tire.This limit is set by the tire manufacturer.
Recommended tire inflation pressure
:
inflation pressure, established by Volvo,which is based on the type of tires that aremounted on a vehicle at the factory. Thisinformation can be found on the tire infla-

If one of the front tires needs to be replaced with a spare tire:
1. Use the spare tire to replace the rear tire
on the same side of the vehicle as the flat tire.
2. Move the rear tire to the front to replace the flat tire.

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 snowtires, 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 tiresWhen switching between regular tires and snow tires, mark the tires according to whichside they were mounted on, e.g. L for left and
R for right.
Studded tiresStudded tires should be broken in by driving500–1000 km (300–600 miles) slowly andgently to help the studs settle properly in thetires. This gives the tire, and especially thestuds, a longer service life.
NOTE
Regulations regarding the use of studded tires vary from country to country.
Tread depthRoad conditions with ice, slush and low tem- peratures place considerably higher demandson tires than summer conditions. Volvo there-fore recommends not driving on snow tiresthat have a tread depth of less than 4 mm(0.15 inch).

Snow chainsUsing snow chains and/or snow tires can help improve traction in winter driving condi-tions.
Volvo does not recommend use of snow chains on wheel dimensions other than 7.5x18ET 45 235/45. Volvo does not recommenduse of snow chains on for Polestar Engi-neered, but AutoSock can be used as a sup-plement to winter tires for the wheel dimen-sion 8x19 ET 42 235/40.
WARNING
Use Volvo genuine snow chains or equiva- lent snow chains that are suitable for thevehicle model and the tire and wheel sizes.Only one-sided snow chains are permit-
ted. If uncertain about snow chains, Volvo rec- ommends contacting an authorized Volvoworkshop. Use of the wrong snow chainscould cause serious damage to the vehicleand result in an accident.
CAUTION
Snow chains can be used on the vehicle, with the following restrictions:
Always follow the manufacturer'sinstallation instructions carefully. Installchains as tightly as possible andretighten periodically.
Only put snow chains on the frontwheels (also applies to all-wheel drivevehicles).
If accessory, aftermarket or "custom"tires and wheels with different dimen-sions than the original tires and wheelsare used, snow chains in some casesmay NOT be used. Sufficient distancebetween the chains and brakes, sus-pension and body components mustbe maintained.
Check local regulations regarding theuse of snow chains before installing.
Never exceed the snow chain manu-facturer's specified maximum speedlimit. Under no circumstances shouldyou exceed 50 km/h (30 mph).
Avoid bumps, holes or sharp turnswhen driving with snow chains.
Avoid driving on surfaces withoutsnow as this wears out both the snowchains and the tires.
The handling of the vehicle can be adversely affected when driving withchains. Avoid fast or sharp turns aswell as locked wheel braking.
Some types of strap-on chains affectbrake components and therefore mustNOT be used.
Consult a Volvo retailer for more information about snow chains.
