WHEELS AND TIRES
500
TiresThe function of the tires is to carry loads, pro- vide traction on road surfaces, reduce vibra-tions and protect the wheels from wear.
The tires significantly influence the vehicle's driving characteristics. The type, dimensions,tire pressure and speed rating have a consid-erable impact on how the vehicle performs. Your vehicle is equipped with tires according to the vehicle's tire information placard on theB-pillar (the structural member at the side ofthe vehicle, at the rear of the driver's dooropening).
WARNING
A damaged tire could cause the driver to lose control of the vehicle.
CAUTION
Some Volvo models are equipped with an Ultra High Performance tire and wheelcombination designed to provide maxi-mum dry pavement performance with con-sideration for hydroplaning resistance.They may be more susceptible to road haz-ard damage and, depending on drivingconditions, may achieve a tread life of lessthan 30,000 km (20,000 miles). Even ifthis vehicle is equipped with Volvo'sadvanced AWD or stability system, thesetires are not designed for winter driving,and should be replaced with winter tireswhen weather conditions dictate.
The tires have good road holding characteris- tics and offer good handling on dry and wetsurfaces. It should be noted however that thetires have been developed to give these fea-tures on snow/ice-free surfaces. Most models are equipped with "all-season" tires, which provide a somewhat higherdegree of roadholding on slippery road surfa-ces than tires without the "all-season" rating.However, for optimal roadholding on icy orsnow-covered roads, Volvo recommendssnow tires on all four wheels. When replacing tires, be sure that the newtires are the same size designation, type(radial) and preferably from the same manu-facturer, on all four wheels. Otherwise there isa risk of altering the vehicle's roadholding andhandling characteristics.
Recommended tiresOn delivery, the car is equipped with Volvo original tires that have the VOL

marking on
the side of the tires. These tires have been designed specifically for your vehicle. It istherefore important when replacing tires thatthe new tires have this same marking to helpmaintain the vehicle's driving characteristics,comfort and fuel consumption.

WHEELS AND TIRES

Tires are perishable goods. After a few years, they will begin to harden and their frictionproperties will gradually deteriorate. Alwaysreplace tires with the freshest tires possible.This is particularly important for snow tires. Aseries of numbers is imprinted on the sidewallof the tire. The last four digits in the series isthe Department of Transportation (DOT)stamp and indicates the week and year thetire was manufactured. The tire in the illustra-tion has 0717 as the last four digits, whichmeans it was manufactured week 7 of 2017.
Tire ageTires degrade over time, even when they arenot being used. It is recommended that tiresgenerally be replaced after 6 years of normalservice. Heat caused by hot climates, frequenthigh loading conditions or Ultra Violet (U.V.)exposure can accelerate the aging process. The temporary spare

should also be replaced
at 6-year intervals, even if it has never been used. A tire with e.g., visible cracks or discol-oration should be replaced immediately.
Tire economy
Maintain correct tire pressure.
Avoid fast starts, hard braking and tirescreeching.
Tire wear increases with speed.
Correct front wheel alignment is veryimportant.
Unbalanced wheels impair tire economyand driving comfort.
Tires must maintain the same direction ofrotation throughout their lifetime.
When replacing tires, the tires with themost tread should be mounted on the rearwheels to reduce the chance of oversteerduring hard braking.
Hitting curbs or potholes can damage thetires and/or wheels permanently.
Tire rotationYour vehicle has no required tire rotation. Driv-ing style, tire pressure, climate and road con-ditions affect how quickly the tires age andexhibit signs of wear. Maintaining the correcttire pressure helps keep tread wear evenly dis-tributed. To help prevent differences in tread depth and wear patterns forming on the tires, the frontand rear wheels should be rotated, i.e. thefront tires moved to the rear and the rear tiresmoved to the front. Ideally, tire rotation shouldbe done the first time after approximately5000 km (ca 3100 miles) and thereafter at10,000 km (approx. 6200 miles) intervals. If you have any questions regarding tread depth, Volvo recommends consulting an authorized Volvo workshop. If significant dif-ferences in wear (> 1 mm difference in treaddepth) between the tires have already occur-red, the least worn tires should always bemounted on the rear wheels. A front-wheelskid (understeer) is usually easier to controlthan a rear-wheel skid (oversteer). If the frontwheels skid, the vehicle will continue in astraight line instead of the rear wheels skid-ding to the side, which could cause you tocompletely lose control of the vehicle. It istherefore important that the rear wheels neverlose grip before the front wheels.
Storing wheels and tiresWhen storing complete wheels (tires mountedon rims), they should be suspended off thefloor or placed on their sides on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but should notbe suspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should never be storedin close proximity to solvents, gasoline,oils, etc.

WARNING
The wheel and tire sizes for your Volvo are specified to meet stringent stabilityand handling requirements. Unap-proved wheel/tire size combinationscan negatively affect your vehicle's sta-bility and handling.
Any damage caused by installation ofunapproved wheel/tire size combina-tions will not be covered by your newvehicle warranty. Volvo assumes noresponsibility for death, injury, orexpenses that may result from suchinstallations.

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.
