sidewall (see the illustration). A tire with e.g., visi- ble cracks or discoloration should be replacedimmediately.
Tire economy
•
Maintain correct tire pressure.
• Avoid fast starts, hard braking and tirescreeching.
• Tire wear increases with speed.
• Correct front wheel alignment is very impor-tant.
• Unbalanced wheels impair tire economy anddriving comfort.
• Tires must maintain the same direction ofrotation throughout their lifetime.
• When replacing tires, the tires with the mosttread should be mounted on the rear wheelsto reduce the chance of oversteer duringhard braking.
• Hitting curbs or potholes can damage thetires and/or wheels permanently.
Tire rotationYour vehicle has no required tire rotation. Tirewear is affected by a number of factors such astire inflation, ambient temperature, driving style,etc.
NOTE
•If the tires are rotated, they should only be moved from front to rear or vice versa.They should never be rotated left toright/right to left.
• Ideally, tire rotation should be done thefirst time after approximately 3,000 miles(5,000 km) and thereafter at 6,000-mile(10,000-km) intervals. Some customersfind that tire rotation may help to getextra mileage from tire life.
• Tire rotation should only be performed iffront/rear tire wear is fairly even andtread height is above 1/16" (1.6 mm).
Storing wheels and tiresWhen storing complete wheels (tires mounted on rims), they should be suspended off the floor orplaced on their sides on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but should not besuspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should never be stored inclose proximity to solvents, gasoline, oils, etc.
WARNING
• The wheel and tire sizes for your Volvo are specified to meet stringent stabilityand handling requirements. Unapprovedwheel/tire size combinations can nega-tively affect your vehicle's stability andhandling.
• Any damage caused by installation ofunapproved wheel/tire size combinationswill not be covered by your new vehiclewarranty. Volvo assumes no responsibilityfor death, injury, or expenses that mayresult from such installations.

Tire sidewall designations
The following information can be found on a tire's sidewall.
Federal law mandates that tire manufacturers place standardized information on the sidewall ofall tires (see the illustration). The vehicle has been certified with certain combi- nations of wheels and tires. The following information is listed on the tire sidewall: The tire designation:
NOTE
Please be aware that the following tire desig- nation is an example only and that this par-
ticular tire may not be available on your vehi- cle.
1. 215 : the width of the tire (in millimeters)
from sidewall edge to sidewall edge. The larger the number, the wider the tire.
2. 65: The ratio of the tire's height to its width
in percent.
3. R: Radial tire (the designation RF and the
symbol indicate that the vehicle is
equipped with optional self-supporting run flat tires 3
.
4. 15: The diameter of the wheel rim (in
inches).
5. 95: The tire's load index. In this example, a
load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maximum
speed at which the tire is designed to bedriven for extended periods of time, carryinga permissible load for the vehicle, and withcorrect inflation pressure. For example, Hindicates a speed rating of 130 mph(210 km/h).
NOTE
The tire's load index and speed rating may not appear on the sidewall because they arenot required by law.
7. M+S or M/S = Mud and Snow, AT = All Ter-
rain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and
indicates that the tire meets all federalstandards. The next two numbers or lettersare the plant code where it was manufac-tured, the next two are the tire size code andthe last four numbers represent the weekand year the tire was built. For example,1510 means that the tire was manufacturedduring week 15 of 2010. The numbers inbetween are marketing codes used at themanufacturer's discretion. This informationhelps a tire manufacturer identify a tire forsafety recall purposes.
9. Tire Ply Composition and Material Used :
Indicates the number of plies indicates or thenumber of layers of rubber-coated fabric inthe tire tread and sidewall. Tire manufactur-ers also must indicate the ply materials in thetire and the sidewall, which include steel,nylon, polyester, and others.
3 Self-supporting run flat tires may not be available on all models
