Tire designations
Federal law mandates that tire manufacturers place standardized information on the sidewall of all tires (see the
illustration).
The following information is listed on the tire sidewall:
The tire designation (the following figures are examples of a tire designation):
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.
3. R: Radial tire.
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 be driven for extended periods of
time, carrying a permissible load for the vehicle, and with correct inflation pressure. For example, H indicates a speed
rating of 130 mph (210 km/h).
NOTE: This information may not appear on the tire because it is not required by law.
7. M+S or M/S = Mud and Snow, AT = All Terrain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and indicates that the tire meets
all federal standards. The next two numbers or letters are the plant code where it was manufactured, the next two are
the tire size code and the last four numbers represent the week and year the tire was built. For example, the numbers
317 mean the 31st week of 1997. After 2000 the numbers go to four digits. For example, 2501 means the 25th week of
2001. The numbers in between are marketing codes used at the manufacturer's discretion. This information helps a tire
manufacturer identify a tire for safety recall purposes.
9. Tire Ply Composition and Material Used : Indicates the number of plies indicates or the number of layers of
rubber-coated fabric in the tire tread and sidewall. Tire manufacturers also must indicate the ply materials in the tire
and the sidewall, which include steel, nylon, polyester, and others.
10. Maximum Load : Indicates the maximum load in pounds and kilograms that can be carried by the tire. Refer to the
vehicle's tire information placard or the safety certification label, located on the B-Pillar or the driver's door or on the
inside of the fuel filler door on Canadian models, for the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperature grades : See page 134
for more information.
12. Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire. This
limit is set by the tire manufacturer.

Glossary of tire terminology
ProCarManuals.com

Tire information placard: A placard showing the OE (Original Equipment) tire sizes, recommended inflation
pressure, and the maximum weight the vehicle can carry.
Tire Identification Number (TIN) : A number on the sidewall of each tire providing information about the tire
brand and manufacturing plant, tire size and date of manufacturer.
Inflation pressure : A measure of the amount of air in a tire.
Standard load: A class of P-metric or Metric tires designed to carry a maximum load at 35 psi [37 psi (2.5 bar) for
Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tires load carrying capability.
Extra load : A class of P-metric or Metric tires designed to carry a heavier maximum load at 41 psi [43 psi (2.9 bar)
for Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tires load carrying
capability.
kPa : Kilopascal, a metric unit of air pressure.
PSI: Pounds per square inch, a standard unit of air pressure.
B-pillar : The structural member at the side of the vehicle behind the door.
Bead area of the tire : Area of the tire next to the rim.
Sidewall of the tire: Area between the bead area and the tread.
Tread area of the tire : Area of the perimeter of the tire that contacts the road when mounted on the vehicle.
Rim: The metal support (wheel) for a tire or a tire and tube assembly upon which the tire beads are seated.
Maximum load rating : a figure indicating the maximum load in pounds and kilograms that can be carried by the
tire. This rating is established by the tire manufacturer.
Maximum permissible inflation pressure : the greatest amount of air pressure that should ever be put in the tire.
This limit is set by the tire manufacturer.
Recommended tire inflation pressure : inflation pressure, established by Volvo, which is based on the type of tires
that are mounted on a vehicle at the factory. This inflation pressure is affected by the number of occupants in the car,
the amount of cargo, and the speed at which the vehicle will be driven for a prolonged period. This information can be
found on the tire inflation placard(s) located on the driver's side B-pillar or on the inside of the fuel filler door on
Canadian models, and in the tire inflation table in this chapter.
Cold tires : The tires are considered to be cold when they have the same temperature as the surrounding (ambient)
air. This temperature is normally reached after the car has been parked for at least 3 hours.

Vehicle loading
Vehicle loading
Properly loading your vehicle will provide maximum return of vehicle design performance.
Before loading your vehicle, familiarize yourself with the following terms for determining your vehicle's weight
ratings, with or without a trailer, from the vehicle's Federal/ Canadian Motor Vehicle Safety Standards
(FMVSS/CMVSS) label, and the vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard equipment. It does not include passengers,
cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipment. When towing, trailer hitch tongue load
is also part of cargo weight.
NOTE: For trailer towing information, please refer to the section "Towing a trailer" on page 120
.
Permissible axle weight
The maximum allowable weight that can be carried by a single axle (front or rear). These numbers are shown on the
Federal/Canadian Motor Vehicle Safety Standards (FMVSS/ CMVSS) label. The total load on each axle must never
exceed its maximum permissible weight.

Tire rotation
Summer and winter tires
When switching between summer and winter tires, mark the tires to indicate where they were mounted on the car,
e.g. LF = left front, RR = right rear
Tires with tread designed to roll in only one direction are marked with an arrow on the sidewall.
Incorrectly mounted tires impair the car's braking properties and ability to force aside rain, snow and slush.
The tires with the most tread should always be at the rear (to reduce the risk of skidding).
Contact a Volvo workshop if you are unsure about the tread depth.

Temporary Spare (option)
The spare tire is called a "Temporary Spare".
Recommended tire pressure (see the placard on the B-pillar or on the fuel filler door) should be maintained irrespective
of which position on the car the temporary spare tire is used. In the event of damage to this tire, a new one can be
purchased from your Volvo retailer.
CAUTION!
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came with
ProCarManuals.com

the car. The use of different size wheels can seriously damage your car's transmission.
Location of the optional spare wheel and tools
The spare wheel is packed in a storage bag and is located under the panel in the floor of the trunk. On cars with a
spare wheel, the jack and lug wrench are secured in a foam plastic block placed in the center of the wheel. The
retaining straps securing the spare wheel is attached to two eyelets in the floor of the spare wheel's storage
compartment.
WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. It must be replaced as soon as possible by a standard tire. Road holding and handling may be affected
with the "Temporary Spare" in use. Do not exceed 50 mph (80 km/h). Do not drive farther than 50 miles (80 km) on
a temporary spare tire.
Accessing the spare wheel:
Open the hatch in the floor of the trunk.
Release the retaining straps and lift out the spare wheel in its storage bag.
Open the zipper on the storage bag and lift out the spare wheel.
The wheel that was replaced by the temporary spare tire can then be placed in the storage bag.

Your vehicle is equipped with a tire sealing system that enables you to temporarily seal a hole in the tread surface and
re-inflate a flat tire, or to adjust a tire's inflation pressure.
The tire sealing kit is stowed behind the ski hatch in the center of the rear seat backrest.
The jack, and lug wrench are secured in a foam plastic block located under the floor panel in the trunk.
The system consists of an air compressor, an integrated container for the sealing compound, wiring to connect the
system to the vehicle's electrical system via one of the 12-volt sockets, and a hose used to connect the system to the
tire's inflation valve.
NOTE:
The tire sealing system is only intended to seal holes on the tire's tread area, not the sidewall.
Tires with large holes or tears cannot be repaired with the tire sealing system.
WARNING!
After using the tire sealing system, the vehicle should not be driven farther than approximately 120 miles (200
km). Have the tire replaced as soon as possible.
The vehicle should not be driven faster than 50 mph (80 km/h) while using a tire that has been temporarily
repaired with the tire sealing system.
After using the tire sealing system, drive carefully and avoid abrupt steering maneuvers and sudden stops.

Temporarily repairing a flat tire
Before using the tire sealing system, observe the following:
WARNING!
Never leave the tire sealing system unattended when it is operating.
Keep the tire sealing system kit away from children.
The vehicle's engine should be running when the tire sealing system is used to avoid battery drain. Therefore, be
sure the vehicle is parked in a well ventilated place before using the system.
Be sure the vehicle is parked safely off the road and away from moving traffic.
Apply the parking brake.
Do not remove any foreign objects (nails, etc.) from the tire.
Temporarily repairing a flat tire is done in two stages.
In the first stage, the hole is sealed by pumping sealing compound into the tire. The car is then driven a short
distance to distribute the sealing compound in the tire.
In the second stage, the tire's inflation pressure is checked and adjusted if necessary.
Stage 1: Sealing the hole
Peel off the speed limit sticker (1) and affix it to the steering wheel hub where it will be clearly visible to the driver.
Ensure that the orange switch (2) is in position 0 (the 0 side of the switch should be pressed down).
Pull out the electrical wire (5) and hose (4) from the side compartment (3).
Remove the valve cap from the tire's inflation valve and screw the hose connector onto the valve as tightly as
possible by hand.
Connect the electrical wire to the nearest 12-volt socket in the vehicle.
Release the safety catch (6) and turn the orange colored section of the sealing kit (7), which holds the sealing
compound container, 90 degrees until it clicks into the vertical position.
Start the vehicle's engine.
Start the tire sealing system's compressor by pressing the switch (2) to position I.
NOTE: The air pressure gauge (9) will temporarily show an increase in pressure to approximately 88 psi (6 bar) while
the sealing compound is being pumped into the tire. The pressure should return to a normal level after approximately
one minute.
pg. 143 Wheels and tires
Tire sealing system
WARNING!
ProCarManuals.com

Contact with the sealing compound may cause skin irritation. If contact occurs, wash the affected area immediately
with soap and water.
Never stand next to the tire being inflated when the compressor is in operation. If cracks, bubbles, etc. form on the
tire, switch off the compressor immediately. If there is visible damage to the sidewall or the rim, the tire cannot be
repaired. The vehicle should not be driven if this occurs. Contact a towing service or Volvo On Call Roadside
Assistance if applicable.
Within seven minutes, inflate the tire to between 22 - 50 psi (1.8 - 3.5 bar). Switch off the compressor briefly to get a
clear reading from the pressure gauge (9).
CAUTION!
If the pressure remains below 22 psi (1.8 bar) after approximately seven minutes, turn off the compressor. In this
case, the hole is too large to be sealed and the vehicle should not be driven.
Disconnect the electrical wire from the 12-volt socket.
Unscrew the hose from the tire's inflation valve and reinstall the valve cap.
Fold down the orange section of the tire sealing system to its original (horizontal) position and press the safety catch
into place.
Safely stow the tire sealing system kit in a convenient place as it will soon be used again to check the tire's inflation
pressure.
Immediately drive the vehicle for approximately 2 miles (3 km) to distribute the sealing compound in the tire.
WARNING!
If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reduce speed and park the car
in a safe place. Recheck the tire for bumps, cracks, or other visible damage, and recheck its inflation pressure. If the
pressure is below 16 psi (1.3 bar), do not continue driving. Have the vehicle towed to a workshop or Volvo retailer.
Stage 2: Checking inflation pressure
Park the car in a safe place.
Ensure that the orange switch (2) is in position 0 (the 0 side of the switch should be pressed down).
Remove the valve cap from the tire's inflation valve and screw the hose connector onto the valve as tightly as
possible by hand.
Connect the electrical wire to the nearest 12-volt socket in the vehicle.
Start the vehicle's engine.
Check the tire's inflation pressure on the gauge (9).
NOTE: In dark conditions, switching on the tire sealing system's compressor will illuminate the pressure gauge.
Inflate the tire to the correct pressure as indicated in the tire inflation tables on page 116. If the tire needs to be
inflated, start the tire sealing system's compressor. If necessary, release air from the tire by pressing the vent button (8).
Turn off the compressor (press switch 2 to the 0 position) when the correct inflation pressure has been reached.

Tire sealing system
CAUTION!
If your vehicle is equipped with the optional Tire Pressure Monitoring System (see page 117
), the use of the sealing
compound may lead to incorrect tire pressure readings or in rare cases, damage to the tire pressure sensor. Use the
tire sealing system to check and adjust the damaged tire's pressure.
After use, return the tire sealing system to its storage compartment behind the ski hatch in the center of the rear seat
backrest.
WARNING!
If you interrupt your trip for more than one hour, check the inflation pressure in the damaged tire again before
continuing. See the section "Stage 2: Checking inflation pressure" on page 143
.
Replacing the sealing compound container
The sealing compound container must be replaced if:
the tire sealing system has been used to repair a tire the container's expiration date has passed (see the date on decal
1).
After use, the container (6), its retaining bracket (9), and the hose (10) must be replaced. Please consult your Volvo
retailer for replacement parts.
See also the safety regulations on the bottom of the container.
WARNING!
Be sure that the compressor is not connected to a 12-volt socket while replacing the container.
