l Tire information placard: A placard showing the OE (Original Equipment) tire sizes, recommende\
d
inflation pressure, and the maximum weight the vehicle can carry.
l 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 manu\
facturer.
l Inflation pressure: A measure of the amount of air in a tire.
l Standard load: A class of P-metric or Metric tires designed to carry a maximum load a\
t 35 psi [37
psi (2.5 bar) for Metric tires]. Increasing the inflation pressure bey\
ond this pressure will not increase the
tires load carrying capability.
l Extra load: A class of P-metric or Metric tires designed to carry a heavier maximu\
m 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.

l Rim: The metal support (wheel) for a tire or a tire and tube assembly upo\
n which the tire beads are
seated.
l 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\
.
l 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.
l 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 inf\
lation pressure is affected by the
number of occupants in the vehicle, the amount of cargo, and the speed a\
t 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 C\
anadian models, and in the tire
inflation table in this chapter.
l Cold tires: The tires are considered to be cold when they have the same temperatur\
e as the
surrounding (ambient) air. This temperature is normally reached after \
the vehicle has been parked for at
least 3 hours.

Vehicle loading
Properly loading your vehicle will provide maximum return of vehicle des\
ign performance.
Before loading your vehicle, familiarize yourself with the following ter\
ms for determining your vehicle's
weight ratings, with or without a trailer, from the vehicle's Federal/ C\
anadian Motor Vehicle Safety
Standards (FMVSS/CMVSS) label, and the vehicle's tire information plac\
ard:
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 equipm\
ent. When towing, trailer hitch
tongue load is also part of cargo weight.
NOTE: For trailer towing information, please refer to the section "Towing a tr\
ailer" on
page 145.
Permissible axle weight
The maximum allowable weight that can be carried by a single axle (fron\
t or rear). These numbers are
shown on the Federal/Canadian Motor Vehicle Safety Standards (FMVSS/ CM\
VSS) label. The total
load on each axle must never exceed its maximum permissible weight.
Gross vehicle weight (GVW)

The vehicle's curb weight + cargo + passengers.
NOTE:
l The location of the various labels in your vehicle can be found on page 213.
l A table listing important weight limits for your vehicle can be found on\
page 215.
Steps for Determining Correct Load Limit
- Locate the statement "the combined weight of occupants and cargo shoul\
d never exceed XXX pounds"
on your vehicle's placard.
- Determine the combined weight of the driver and passengers that will b\
e riding in your vehicle.
- Subtract the combined weight of the driver and passengers from XXX kil\
ograms or XXX pounds.
- The resulting figure equals the available amount of cargo and luggage \
load capacity. For example, if
the "XXX" amount equals 1400 lbs. and there will be five 150 lb. passeng\
ers in your vehicle, the amount
of available cargo and luggage load capacity is 650 lbs. (1400- 750 (5\
x 150) = 650 lbs.)
- Determine the combined weight of luggage and cargo being loaded on the\
vehicle. That weight may
not safely exceed the available cargo and luggage load capacity calculat\
ed in Step 4.
- If your vehicle will be towing a trailer, load from your trailer will \
be transferred to your vehicle.
Consult this manual
1 to determine how this reduces the available cargo and luggage load capa\
city of
your vehicle.

WARNING!
l Exceeding the permissible axle weight, gross vehicle weight, or any othe\
r weight rating limits can
cause tire overheating resulting in permanent deformation or catastrophi\
c failure.
l Do not use replacement tires with lower load carrying capacities than th\
e tires that were original
equipment on the vehicle because this will lower the vehicle's GVW ratin\
g. Replacement tires with a
higher limit than the originals do not increase the vehicle's GVW rating\
limitations.

ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY
REQUIREMENTS IN ADDITION TO THESE GRADES
Quality grades can be found, where applicable, on the tire sidewall betw\
een the tread shoulder
and maximum section width. For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of th\
e tire when tested under
controlled conditions on a specified government test course. For example\
, a tire graded 150 would wear
one and one half (1 1/2) times as well on the government course as a t\
ire graded 100. The relative
performance of tires depends upon the actual conditions of their use, ho\
wever, and many depart
significantly from the norm due to variation in driving habits, maintena\
nce practices and differences in
road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as mea\
sured under controlled
conditions on specified government test surfaces of asphalt and concrete\
. A tire marked C may have
poor traction performance.
WARNING!
The traction grade assigned to this tire is based on braking (straight-\
ahead) traction tests and is not a
measure of cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing\
the tire's resistance to the
generation of heat and its ability to dissipate heat when tested under c\
ontrolled conditions on a specified
indoor laboratory test wheel. Sustained high temperature can cause the m\
aterial of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire \
failure. The grade C corresponds
to a minimum level of performance that all passenger vehicle tires must \
meet under the Federal Motor
Safety Standard No. 109. Grades B and A represent higher levels of perfo\
rmance on the laboratory test
wheel than the minimum required by law.
WARNING!
The temperature grade for this tire is established for a tire that is pr\
operly inflated and not overloaded.
Excessive speed, under-inflation, or excessive loading, either separatel\
y or in combination, can cause
heat buildup and tire failure.

Snow chains, snow tires, studded tires
Snow chains
Snow chains can be used on your Volvo with the following restrictions:
l Snow chains should be installed on front wheels only. Use only Volvo app\
roved snow chains.
l If accessory, aftermarket or "custom" tires and wheels are installed and\
are of a size different than the
original tires and wheels, chains in some cases CANNOT be used. Sufficie\
nt clearances between chains
and brakes, suspension and body components must be maintained.
l Some strap-on type chains will interfere with brake components and there\
fore CANNOT be used.
l All Wheel Drive models: Snow chains should only be installed on the fron\
t wheels. Only chains
adapted for AWD models should be used.
Consult your Volvo retailer for additional snow chain information.
CAUTION!
- Check local regulations regarding the use of snow chains before instal\
ling. Always follow the chain
manufacturer's installation instructions carefully. Install chains as ti\
ghtly as possible and retighten
periodically.
- Never exceed the chain manufacturer's specified maximum speed limit. (\
Under no circumstances
should you exceed 31 mph (50 km/h)).
- Avoid bumps, holes or sharp turns when driving with snow chains.
- The handling of the vehicle can be adversely affected when driving wit\
h chains. Avoid fast or sharp
turns as well as locked wheel braking.
Snow tires, studded tires

Tires for winter use:
l Owners who live in or regularly commute through areas with sustained per\
iods of snow or icy driving
conditions are strongly advised to fit suitable winter tires to help ret\
ain the highest degree of traction.
l It is important to install winter tires on all four wheels to help retai\
n traction during cornering,
braking, and accelerating. Failure to do so could reduce traction to an \
unsafe level or adversely affect
handling.
l Do not mix tires of different design as this could also negatively affec\
t overall tire road grip.
l Winter tires wear more quickly on dry roads in warm weather. They should\
be removed when the
winter driving season has ended.
l Studded tires should be run-in 300-600 miles (500-1000 km) during whic\
h the vehicle should be
driven as smoothly as possible to give the studs the opportunity to seat\
properly in the tires. The tires
should have the same rotational direction throughout their entire lifeti\
me.

Temporary spare
The spare tire in your vehicle is called a "Temporary Spare".
Recommended tire pressure (see the placard on the B-pillar or on the fu\
el filler door) should be
maintained irrespective of which position on the vehicle the temporary s\
pare tire is used on.
In the event of damage to this tire, a new one can be purchased from you\
r Volvo retailer.
WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire othe\
r than as a temporary
replacement for a punctured tire. It must be replaced as soon as possibl\
e 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 spar\
e tire.
CAUTION!
The vehicle must not be driven with wheels of different dimensions or wi\
th a spare tire other than the
one that came with the vehicle. The use of different size wheels can ser\
iously damage your vehicle's
transmission.
