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 rotation
Your 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 onlybe 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 tires
When storing complete wheels (tires mounted onrims), they should be suspended off the floor orplaced on their sides on the floor.
Tires not mounted on rims should be stored ontheir 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 Volvoare 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.

12.Maximum permissible inflationpressure: the greatest amount of air pres-sure that should ever be put in the tire. Thislimit is set by the tire manufacturer.

Speed Symbol
A tire's Speed Symbol (SS) indicates the maxi-mum speed for which the tire has been certifiedand should be at least equivalent to the vehicle'stop speed.
Winter tires, with our without studs, are excep-tions and may use a lower SS. When winter tiresare installed, the vehicle may not be driven fasterthan the tires' SS.
The vehicle's speed should always be determinedby the posted speed limit and traffic and roadconditions, not the tire's SS.
The following table indicates the maximum per-missible speed for each SS.

Tire terminology
The following is a glossary of tire-related terms.
The tire suppliers may have additional markings,notes or warnings such as standard load, radialtubeless, etc.
•Tire information placard: A placard show-ing the OE (Original Equipment) tire sizes,recommended inflation pressure, and themaximum weight the vehicle can carry.
•Tire Identification Number (TIN): A numberon the sidewall of each tire providing infor-mation about the tire brand and manufactur-ing plant, tire size and date of manufacturer.
•Inflation pressure: A measure of theamount of air in a tire.
•Standard load: A class of P-metric or Metrictires designed to carry a maximum load at35 psi [37 psi (2.5 bar) for Metric tires].Increasing the inflation pressure beyond thispressure will not increase the tires load car-rying capability.
•Extra load: A class of P-metric or Metrictires 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 pressure.
•PSI: Pounds per square inch, a standard unitof air pressure.
•B-pillar: The structural member at the sideof the vehicle behind the front door.
•Bead area of the tire: Area of the tire nextto the rim.
•Sidewall of the tire: Area between the beadarea 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 atire and tube assembly upon which the tirebeads are seated.
•Maximum load rating: a figure indicatingthe maximum load in pounds and kilogramsthat can be carried by the tire. This rating isestablished by the tire manufacturer.
•Maximum permissible inflation pressure:the greatest amount of air pressure thatshould ever be put in the tire. This limit is setby 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 inflationplacard(s) located on the driver's side B-pillarand in the tire inflation table in this chapter.
•Cold tires: The tires are considered to becold when they have the same temperatureas the surrounding (ambient) air. This tem-
perature is normally reached after the vehiclehas been parked for at least 3 hours.

Loading specifications
Properly loading your vehicle will provide maxi-mum return of vehicle design performance.

Weight designations
Before loading your vehicle, familiarize yourselfwith the following terms for determining yourvehicle's weight ratings, with or without a trailer,from the vehicle's Federal/Canadian Motor Vehi-cle Safety Standards (FMVSS/CMVSS) label, andthe vehicle's tire information placard:

Curb weight
The weight of the vehicle including a full tank offuel and all standard equipment. It does notinclude passengers, cargo, or optional equipment.

Capacity weight
All weight added to the curb weight, includingcargo and optional equipment. When towing,trailer hitch tongue load is also part of cargoweight.

Permissible axle weight
The maximum allowable weight that can be car-ried by a single axle (front or rear). These num-bers are shown on the Federal/Canadian MotorVehicle Safety Standards (FMVSS/CMVSS) label.The total load on each axle must never exceed itsmaximum permissible weight.

Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weightof occupants and cargo should never exceedXXX kg or XXX lbs." on your vehicle's plac-ard.
2. Determine the combined weight of the driverand passengers that will be riding in yourvehicle.
3. Subtract the combined weight of the driverand passengers from XXX kg or XXX lbs.
4. The resulting figure equals the availableamount of cargo and luggage load capacity.For example, if the "XXX" amount equals1400 lbs. and there will be five 150 lb. pas-sengers in your vehicle, the amount of availa-ble cargo and luggage load capacity is650 lbs. (1400 – 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggageand cargo being loaded on the vehicle. Thatweight may not safely exceed the availablecargo and luggage load capacity calculatedin Step 4.
6. If your vehicle will be towing a trailer, loadfrom your trailer will be transferred to yourvehicle. Consult this manual to determinehow this reduces the available cargo and lug-gage load capacity of your vehicle.
WARNING
•Exceeding the permissible axle weight,gross vehicle weight, or any other weightrating limits can cause tire overheatingresulting in permanent deformation orcatastrophic failure.
•Do not use replacement tires with lowerload carrying capacities than the tires thatwere original equipment on the vehiclebecause this will lower the vehicle's GVWrating. Use only tires with the correct loadcarrying capacity. Consult your Volvoretailer for information.

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUSTCONFORM TO FEDERAL SAFETY REQUIRE-MENTS IN ADDITION TO THESE GRADES.
Quality grades can be found, where applica-ble, on the tire sidewall between the treadshoulder and maximum section width. Forexample:
Treadwear 200 Traction AA Temperature A

TREADWEAR
The treadwear grade is a comparative ratingbased on the wear rate of the tire when testedunder controlled conditions on a specified gov-ernment test course. For example, a tire graded150 would wear one and one half (1 ½) times aswell on the government course as a tire graded100. The relative performance of tires dependsupon the actual conditions of their use, however,and many depart significantly from the norm dueto variation in driving habits, maintenance practi-ces and differences in road characteristics andclimate.

TRACTION
The traction grades, from highest to lowest, areAA, A, B, and C, as measured under controlledconditions on specified government test surfacesof asphalt and concrete. A tire marked C mayhave poor traction performance. The tractiongrade assigned to this tire is based on braking
(straight-ahead) traction tests and is not a meas-ure of cornering (turning) traction.
WARNING
The traction grade assigned to this tire isbased on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.

TEMPERATURE
The temperature grades are A (the highest), B,and C, representing the tire's resistance to thegeneration of heat and its ability to dissipate heatwhen tested under controlled conditions on aspecified indoor laboratory test wheel. Sustainedhigh temperature can cause the material of thetire to degenerate and reduce tire life, and exces-sive temperature can lead to sudden tire failure.The grade C corresponds to a minimum level ofperformance that all passenger vehicle tires mustmeet under the Federal Motor Safety StandardNo. 109. Grades B and A represent higher levelsof performance on the laboratory test wheel thanthe minimum required by law.

WARNING
The temperature grade for this tire is estab-lished for a tire that is properly inflated andnot overloaded. Excessive speed, under-infla-tion, or excessive loading, either separately orin combination, can cause heat buildup andtire failure.
Snow tires and chains
The use of snow chains and/or winter tires canhelp improve traction in winter driving conditions.
Snow chains can be used on your Volvo with thefollowing restrictions:
•Snow chains should be installed on frontwheels only. Use only Volvo approved snowchains.
•If accessory, aftermarket or "custom" tiresand wheels are installed and are of a size dif-ferent than the original tires and wheels,chains in some cases CANNOT be used.Sufficient clearances between chains andbrakes, suspension and body componentsmust be maintained.
•Some strap-on type chains will interfere withbrake components and therefore CANNOTbe used.
•All Wheel Drive models: Snow chainsshould only be installed on the front wheels.
•Certain size tires may not allow the assemblyof snow chains/traction devices.
Consult your Volvo retailer for additional snowchain information.
