Changing a wheel – spare wheel Wheel changes should always be carried out correctly.
Spare tireA spare tire can be purchased for your vehicle as an accessory. Follow the instructions includedwith the spare tire regarding use and stowing inthe vehicle. See also Changing a wheel – remov-ing wheel (p. 303) for additional information.
Spare wheelThe following instructions only apply if you have purchased a temporary spare wheel * for your
vehicle. If there is no temporary spare wheel in your vehi- cle, please see Tire sealing system * – general
information (p. 324) for instructions on using the tire sealing system. The accessory temporary spare wheel is provided in a bag that must be securely strapped in placein the cargo area while the vehicle is beingdriven. The spare wheel is only intended for temporary use. Replace it with a normal wheel as soon aspossible. The vehicle's handling may be alteredby the use of the spare wheel. The correct tirepressure is stated in the tire pressure table, seethe tire inflation decal on the driver's door open-ing.Turn the handle on the spare wheel bag out toward you. Secure the stitched strap hooks inthe front loading eyelets. Secure the long strap inone of the front loading eyelets, wrap the strapdiagonally over the spare wheel and through theupper handle. Secure the short strap on the longstrap. Secure in the rear loading eyelet andtighten.
WARNING
Current legislation prohibits the use of the “Temporary Spare” tire other than as a tempo-rary replacement for a punctured tire. It mustbe replaced as soon as possible by a stand-ard tire. Road holding and handling may beaffected with the “Temporary Spare” in use.
CAUTION
The vehicle must never be driven with more than one temporary spare wheel.

Tire inflation – general information
Check tire inflation pressure regularly.

Tire inflation placard
Tire inflationSee the tire inflation decal on the driver's door opening. This decal indicates the designation ofthe factory-mounted tires on your vehicle, as wellas load limits and inflation pressure.
NOTE
• The placards shown indicate inflation pressure for the tires installed on thevehicle at the factory only.
• A certain amount of air seepage from thetires occurs naturally and tire pressurefluctuates with seasonal changes in tem-perature. Always check tire pressure reg-ularly.
•Use a tire gauge to check the tire inflation pressure, including the spare 2
, at least once
a month and before long trips. You are strongly urged to buy a reliable tire pressuregauge, as automatic service station gaugesmay be inaccurate.
• Use the recommended cold inflation pres-sure for optimum tire performance and wear.
• Under-inflation or over-inflation may causeuneven treadwear patterns.

WARNING
•Under-inflation is the most common cause of tire failure and may result insevere tire cracking, tread separation, or"blow-out," with unexpected loss of vehi-cle control and increased risk of injury.
• Under-inflated tires reduce the load car-rying capacity of your vehicle.
When weather temperature changes occur, tire inflation pressures also change. A 10-degreetemperature drop causes a corresponding dropof 1 psi (7 kPa) in inflation pressure. Check yourtire pressures frequently and adjust them to theproper pressure, which can be found on the vehi-cle's tire information placard or certification label.

Tire inflation – checking pressure
Inflation pressure should be checked when the tires are cold.
Cold tires
The tires are considered to be cold when they have the same temperature as the sur-rounding (ambient) air. This temperature is normally reached after the vehicle has been parked for at least 3 hours. After driving a distance of approximately 1 mile (1.6 km), the tires are considered to be hot. If youhave to drive farther than this distance to pumpyour tire(s), check and record the tire pressurefirst and add the appropriate air pressure whenyou get to the pump. If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tiresare hot from driving and it is normal for pressuresto increase above recommended cold pressures.A hot tire at or below recommended cold inflationpressure could be significantly under-inflated.
To check inflation pressure:
1. Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve.
2. Add air to reach the recommended air pres- sure. 3. Replace the valve cap.
CAUTION
•
After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
4. Visually inspect the tires to make sure there
are no nails or other objects embedded that could puncture the tire and cause an air leak.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregulari-ties.
6. Repeat this procedure for each tire, including the spare 3
.
NOTE
• If you overfill the tire, release air by push- ing on the metal stem in the center of thevalve. Then recheck the pressure withyour tire gauge.
• Some spare tires (available as an acces-sory) require higher inflation pressurethan the other tires. Consult the tire infla-

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 4
.
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 MaterialUsed : Indicates the number of plies indi-
cates or the number of layers of rubber-coated fabric in the tire tread and sidewall.Tire manufacturers also must indicate the plymaterials in the tire and the sidewall, whichinclude steel, nylon, polyester, and others.
10. Maximum Load : Indicates the maximum
load in pounds and kilograms that can becarried by the tire. Refer to the vehicle's tireinformation placard located on the B-Pillarfor the correct tire pressure for your vehicle. 11.
Treadwear, Traction, and Temperaturegrades : see Tire specifications – Uniform
Tire Quality Grading (p. 314) for more infor-mation.
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.

6. If your vehicle will be towing a trailer, load
from your trailer will be transferred to your vehicle. 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.

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 chains
Snow chains can be used on your Volvo with the following restrictions:
• Snow chains should be installed on front wheels 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 chains
should 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.
CAUTION
• Check local regulations regarding the use of snow chains before installing.
• Use single-sided snow chains only.
• Always follow the chain manufacturer'sinstallation instructions carefully. Installchains as tightly as possible andretighten periodically.
• Never exceed the chain manufacturer'sspecified maximum speed limit. (Underno circumstances should you exceed31 mph (50 km/h).
• Avoid bumps, holes or sharp turns whendriving with snow chains.
• The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns as wellas locked wheel braking.

Snow tires/studded tires5
Owners who live in or regularly commute through areas with sustained periods of snow oricy driving conditions are strongly advised to fitsuitable winter tires to help retain the highestdegree of traction.
Tires for winter use:
• It is important to install winter tires on all four wheels to help retain traction during corner-ing, braking, and accelerating. Failure to doso could reduce traction to an unsafe level oradversely affect handling.
• Do not mix tires of different design as thiscould also negatively affect overall tire roadgrip.
• Winter tires wear more quickly on dry roadsin warm weather. They should be removedwhen the winter driving season has ended.
• Studded tires should be run-in 300 – 600 miles (500 – 1000 km) during whichthe vehicle should be driven as smoothly aspossible to give the studs the opportunity toseat properly in the tires. The tires shouldhave the same rotational direction through-out their entire lifetime.
NOTE
Please consult state or provincial regulations restricting the use of studded winter tiresbefore installing such tires.
