Federal law mandates that tire manufacturers place standardized informat\
ion 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 desi\
gnation):
1. 215: the width of the tire (in millimeters) from sidewall edge to sidewal\
l 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 ma\
ximum load of 1521 lbs (690
kg).
6. H: The tire's speed rating, or the maximum speed at which the tire is des\
igned to be driven for extended
periods of time, carrying a permissible load for the vehicle, and with c\
orrect 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 b\
y
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 ar\
e the plant code where it was
manufactured, the next two are the tire size code and the last four numb\
ers represent the week and year
the tire was built. For example, the numbers 317 mean the 31st week of 1\
997. After 2000 the numbers go
to four digits. For example, 2501 means the 25th week of 2001. The numbe\
rs in between are marketing
codes used at the manufacturer's discretion. This information helps a ti\
re 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 manu\
facturers also must indicate the ply
materials in the tire and the sidewall, which include steel, nylon, poly\
ester, 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 certificat\
ion label, located on the B-Pillar or
the driver's door or on the inside of the fuel filler door on Canadian m\
odels, for the correct tire pressure
for your vehicle.
11. Treadwear, Traction, and Temperature grades: See
page 163 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
Tire terminology
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 manufactur\
er.
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 beyond \
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 bey\
ond this pressure will not increase the
tires load carrying capability.
l kPa: Kilopascal, a metric unit of air pressure.
l PSI: Pounds per square inch, a standard unit of air pressure.
l B-pillar: The structural member at the side of the vehicle behind the front door\
.
l Bead area of the tire: Area of the tire next to the rim.
l Sidewall of the tire: Area between the bead area and the tread.
l Tread area of the tire: Area of the perimeter of the tire that contacts the road when mounted \
on the
vehicle.

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 inflati\
on 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 infla\
tion 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 car has \
been parked for at least 3 hours.

Vehicle loading
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/Ca\
nadian Motor Vehicle Safety
Standards (FMVSS/ CMVSS) label, and the vehicle's tire information pla\
card:
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

The traction grade assigned to this tire is based on braking (straight-\
ahead) traction tests and is not a
measure of cornering (turning) traction.
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 material of the tire to degener\
ate 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 passe\
nger vehicle tires must meet
under the Federal Motor Safety Standard No. 109. Grades B and A represen\
t higher levels of performance
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.

Tire sealing system
Tire sealing system
Your vehicle is equipped with a tire sealing system that enables you to \
temporarily seal a hole in the tread
surface and reinflate a flat tire, or to adjust a tire's inflation press\
ure.
l The tire sealing kit is stowed behind the ski hatch in the center of the\
rear seat backrest.

2007 Volvo C70
The system consists of an air compressor, an integrated container for th\
e 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 tre\
ad area, not the
sidewall.
l Tires with large holes or tears cannot be repaired with the tire sealing\
system.
WARNING
l After using the tire sealing system, the vehicle should not be driven fa\
rther than approximately 120
miles (200 km). Have the tire replaced as soon as possible.
l The vehicle should not be driven faster than 50 mph (80 km/h) while us\
ing a tire that has been
temporarily repaired with the tire sealing system.
l After using the tire sealing system, drive carefully and avoid abrupt st\
eering maneuvers and sudden
stops.
l A tire that has been temporarily inflated with the tire sealing kit cann\
ot be repaired and re-used. It
must be replaced.

Temporarily repairing a flat tire
Before using the tire sealing system, observe the following:
WARNING
l Never leave the tire sealing system unattended when it is operating.
l Keep the tire sealing system kit away from children.
l The vehicle's engine should be running when the tire sealing system is u\
sed to avoid battery drain.
Therefore, be sure the vehicle is parked in a well ventilated place befo\
re using the system.
l Be sure the vehicle is parked safely off the road and away from moving t\
raffic.
l Apply the parking brake.
l Do not remove any foreign objects (nails, etc.) from the tire.
172 07 Wheels and tires
Tire sealing system
Temporarily repairing a flat tire is done in two stages
l 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.
l In the second stage, the tire's inflation pressure is checked and adjust\
ed if necessary.
Stage 1 - Sealing the hole
Peel off the speed limit sticker (1) and affix it to the steering whee\
l hub where it will be clearly visible to
the driver.
