Tire direction of rotation Tires with tread designed to roll in only one direction are marked with an arrow on thesidewall.
The arrow shows the tire's direction of rotation.
The tire should maintain the same direc- tion of rotation throughout its service life.
Tires should only be moved between thefront and back, never from right to left orvice versa.
Incorrectly mounted tires impair the vehi-cle's braking properties and ability to forceaside rain, snow and slush.
The tires with the most tread shouldalways be mounted on the rear wheels tohelp reduce the risk of skidding.
NOTE
Use tires of the same type, dimensions and make (manufacturer) on each axle.

530 the system is not operating properly. The TPMS malfunction indicator is combined withthe low tire pressure telltale. When the systemdetects a malfunction, the telltale will flash forapproximately one minute and then remaincontinuously illuminated. This sequence willcontinue upon subsequent vehicle start-ups aslong as the malfunction exists. When the mal-function indicator is illuminated, the systemmay not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replace-ment or alternate tires or wheels on the vehi-cle that prevent the TPMS from functioningproperly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels onyour vehicle to ensure that the replacement oralternate tires and wheels allow the TPMS tocontinue to function properly.
Messages in the instrument panelIf tire pressure is too low, the low tire pressurewarning symbol is shown in the instrumentpanel along with a message. Check the infla- tion pressure in the
Car Status app in the
center display.

To keep in mind
Always save the new inflation pressure in the system after changing a tire or adjust-ing the inflation pressure.
If you switch to a tire of another size thanthe factory-mounted tires, the systemmust be reset by storing a new inflationpressure for these tires to avoid falsewarnings.
If a spare wheel 8
is used, it is possible that
the tire pressure monitoring system willnot work correctly due to the differencesbetween the wheels.
The system does not replace the need forregular tire inspection and maintenance.
It is not possible to deactivate the tirepressure monitoring system.
WARNING
Incorrect inflation pressure could lead to tire failure, which could cause thedriver to lose control of the vehicle.
The system cannot predict sudden tiredamage.

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 chains
Using 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 larger than18 inches.
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.
