WARNING
19” wheels may never be used on vehicles
that are not equipped with the R-design or
the Sport chassis options. Using 19” wheels on vehicles equipped the standard chassis presents a safety
risk and the risk of damage to the vehicle,and impairs the vehicle’s driving characte-ristics.
NOTE
Please consult a Volvo retailer’s Parts department for the most up-to-date speci-fications.

Federal law mandates that tire manufacturers place standardized information on the side-wall of all tires (see the illustration). The following information is listed on the tire sidewall: The tire designation:
NOTE
Please be aware that the following tire designation is an example only and that
this particular tire may not be available onyour vehicle.
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 1
. See page 334 for more
information about these tires).
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 maxi-
mum speed at which the tire is designedto be driven for extended periods of time,carrying a permissible load for the vehi-cle, and with correct inflation pressure.For example, H indicates a speed ratingof 130 mph (210 km/h).
NOTE
The tire's load index and speed rating may not appear on the sidewall because theyare 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 fed- eral standards. The next two numbers orletters are the plant code where it wasmanufactured, the next two are the tiresize code and the last four numbers rep-resent the week and year the tire wasbuilt. For example, 1510 means that thetire was manufactured during week 15 of2010. The numbers in between are mar-keting codes used at the manufacturer'sdiscretion. This information helps a tiremanufacturer identify a tire for safetyrecall purposes.
9. Tire Ply Composition and Material Used
: Indicates the number of plies indi-
cates or the number of layers of rubber- coated fabric in the tire tread and side-wall. Tire manufacturers also must indi-cate the ply materials in the tire and thesidewall, which include steel, nylon, poly-ester, and others.
1 Self-supporting run flat tires may not be available on all models

10.
Maximum Load : Indicates the maximum
load in pounds and kilograms that can be carried by the tire. Refer to the vehicle'stire information placard located on the B-Pillar for the correct tire pressure for yourvehicle.
11. Treadwear, Traction, and Temperature grades
: see page 319 for more informa-
tion.
12. Maximum permissible inflationpressure:
the greatest amount of air
pressure that should ever be put in the tire. This limit is set by the tire manufac-turer.

Terms
The tire suppliers may have additional mark- ings, notes or warnings such as standardload, radial tubeless, etc.
• Tire information placard
: A placard
showing the OE (Original Equipment) tire sizes, recommended inflation pressure,and the maximum weight the vehicle cancarry.
• Tire Identification Number (TIN)
: A
number on the sidewall of each tire pro-viding information about the tire brandand manufacturing plant, tire size anddate 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 maximumload at 35 psi [37 psi (2.5 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetires load carrying capability.
• Extra load
: A class of P-metric or Metric
tires designed to carry a heavier maxi-mum load at 41 psi [43 psi (2.9 bar) forMetric tires]. Increasing the inflation pres-sure beyond this pressure will notincrease the tire's load carrying capabil-ity.
• kPa
: Kilopascal, a metric unit of air pres-
sure. •
PSI
: Pounds per square inch, a standard
unit of air pressure.
• B-pillar
: The structural member at the
side of the vehicle behind the front 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 perim-
eter of the tire that contacts the roadwhen mounted on the vehicle.
• Rim
: The metal support (wheel) for a tire
or a tire and tube assembly upon whichthe tire beads are seated.
• Maximum load rating
: a figure indicating
the maximum load in pounds and kilo-grams that can be carried by the tire. Thisrating is established by the tire manufac-turer.
• 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 manufac-turer.
• Recommended tire inflation pressure
:
inflation pressure, established by Volvo,which is based on the type of tires thatare mounted on a vehicle at the factory.This information can be found on the tireinflation placard(s) located on the driver's side B-pillar and in the tire inflation tablein this chapter.
• Cold tires
: The tires are considered to be
cold when they have the same tempera-ture as the surrounding (ambient) air. Thistemperature is normally reached after thevehicle has been parked for at least3 hours.

Loads
Properly loading your vehicle will provide maximum return of vehicle design perform-ance. Before loading your vehicle, familiarize your- self with the following terms for determiningyour vehicle's weight ratings, with or withouta trailer, from the vehicle's Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label, and the vehicle's tire informa-tion placard:
Curb weightThe weight of the vehicle including a full tankof fuel and all standard equipment. It doesnot include passengers, cargo, or optionalequipment.
Capacity weightAll weight added to the curb weight, includingcargo and optional equipment. When towing,trailer hitch tongue load is also part of cargoweight.
NOTE
For trailer towing information, please refer to the section "Towing a trailer" on page300.
Permissible axle weightThe maximum allowable weight that can be carried by a single axle (front or rear). Thesenumbers are shown on the Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label. The total load on each axlemust never exceed its maximum permissibleweight.
Gross vehicle weight (GVW)The vehicle's curb weight + cargo + passen-gers.
NOTE
•The location of the various labels in your vehicle can be found on page380.
• A table listing important weight limitsfor your vehicle can be found on page384.
Steps for Determining Correct Load Limit
1. Locate the statement "the combined
weight of occupants and cargo should never exceed XXX pounds" on your vehi-cle's placard. 2. Determine the combined weight of the
driver and passengers that will be ridingin your vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kilo-grams or XXX pounds.
4. The resulting figure equals the available amount of cargo and luggage loadcapacity. For example, if the "XXX"amount equals 1400 lbs. and there will befive 150 lb. passengers in your vehicle,the amount of available cargo and lug-gage load capacity is 650 lbs. (1400 – 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of lug- gage and cargo being loaded on the vehi-cle. That weight may not safely exceedthe available cargo and luggage loadcapacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual 1
to deter-
mine how this reduces the available cargo and luggage load capacity of yourvehicle.

WARNING
•Exceeding the permissible axle weight, gross vehicle weight, or any otherweight rating limits can cause tireoverheating resulting in permanentdeformation or catastrophic failure.
• Do not use replacement tires withlower load carrying capacities than thetires that were original equipment onthe vehicle because this will lower thevehicle's GVW rating. Use only tireswith the correct load carrying capacity.Consult your Volvo retailer for informa-tion.
