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 located on the B-Pillar
for the correct tire pressure for your vehicle.
11.
Treadwear, Traction, and Temperature
grades
.
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.
Speed Symbol
A tire's Speed Symbol (SS) indicates the maxi-
mum speed for which the tire has been certified
and should be at least equivalent to the vehicle's
top speed.
Winter tires, with our without studs, are excep-
tions and may use a lower SS. When winter tires
are installed, the vehicle may not be driven faster
than the tires' SS.
The vehicle's speed should always be determined
by the posted speed limit and traffic and road
conditions, not the tire's SS.
The following table indicates the maximum per-
missible speed for each SS.
Speed Symbol
M 81 mph (130 km/h)
Q 100 mph (160 km/h)
T 118 mph (190 km/h)
H 130 mph (210 km/h)
V 149 mph (240 km/h)
W 168 mph (270 km/h)
Y 186 mph (300 km/h)
WARNING
•
The wheel and tire sizes for your Volvo
are specified to meet stringent stability
and handling requirements. Unapproved
wheel/tire size combinations can nega-
tively affect your vehicle's stability and
handling.
•
Any damage caused by installation of
unapproved wheel/tire size combinations
will not be covered by your new vehicle
warranty. Volvo assumes no responsibility
for death, injury, or expenses that may
result from such installations.
Tire terminology
The following is a glossary of tire-related terms.
The tire suppliers may have additional markings,
notes or warnings such as standard load, radial
tubeless, etc.
•
Tire information placard
: A placard show-
ing 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 infor-
mation about the tire brand and manufactur-
ing 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 car-
rying 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
tire's load carrying capability.
•
kPa
: Kilopascal, a metric unit of air pressure.
•
PSI
: Pounds per square inch, a standard unit
of air pressure.
