Information Contained on the Tire
Sidewall
Both United States and Canada Federal
regulations require tire manufacturers
to place standardized information on the
sidewall of all tires. This information
identifies and describes the fundamental
characteristics of the tire and also
provides a U.S. DOT Tire Identification
Number for safety standard certification
and in case of a recall.
Information on P Type Tires P215/65R15 95H is an example of a tire
size, load index and speed rating. The
definitions of these items are listed
below. (Note that the tire size, load index
and speed rating for your vehicle may
be different from this example.)A. P: Indicates a tire, designated by the
Tire and Rim Association, that may be
used for service on cars, sport utility
vehicles, minivans and light trucks.
Note:
If your tire size does not begin with a
letter this may mean it is designated by
either the European Tire and Rim
Technical Organization or the Japan Tire
Manufacturing Association.
B.
215: Indicates the nominal width of
the tire in millimeters from sidewall edge
to sidewall edge. In general, the larger
the number, the wider the tire.
C.
65: Indicates the aspect ratio which
gives the tire's ratio of height to width.
D.
R: Indicates a radial type tire.
E.
15: Indicates the wheel or rim
diameter in inches. If you change your
wheel size, you will have to purchase
new tires to match the new wheel
diameter.

F. 95: Indicates the tire's load index. It
is an index that relates to how much
weight a tire can carry. You may find this
information in your owner’ s manual. If
not, contact a local tire dealer.
Note: You may not find this information
on all tires because it is not required by
federal law.
G.
H: Indicates the tire's speed rating.
The speed rating denotes the speed at
which a tire is designed to be driven for
extended periods of time under a
standard condition of load and inflation
pressure. The tires on your vehicle may
operate at different conditions for load
and inflation pressure. These speed
ratings may need to be adjusted for the
difference in conditions. The ratings
range from
81 mph (130 km/h) to
186 mph (299 km/h). These ratings are
listed in the following chart.
Note: You may not find this information
on all tires because it is not required by
federal law. Speed rating

Note: For tires with a maximum speed
capability over 149 mph (240 km/h), tire
manufacturers sometimes use the letters
ZR. For those with a maximum speed
capability over 186 mph (299 km/h), tire
manufacturers always use the letters
ZR.
H. 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
designating 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
408
Corsair (CTF) Canada/United States of America, enUSA, Edition date: 202007, First-Printing Wheels and Tires

go to four digits. For example, 2501
means the 25th week of 2001. The
numbers in between are identification
codes used for traceability. This
information is used to contact customers
if a tire defect requires a recall.
I. M+S or M/S: Mud and Snow, or
AT:
All Terrain, or
AS:
All Season.
J.
Tire Ply Composition and Material
Used: Indicates the number of plies 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. K.
Maximum Load: Indicates the
maximum load in kilograms and pounds
that can be carried by the tire. See the
Safety Compliance Certification Label
(affixed to either the door hinge pillar,
door-latch post, or the door edge that
meets the door-latch post, next to the
driver's seating position), for the correct
tire pressure for your vehicle.
L.
Treadwear, Traction and
Temperature Grades:
*
Treadwear: The treadwear grade is a
comparative rating based on the wear
rate of the tire when tested under
controlled conditions on a specified
government test course. For example,
a tire graded 150 would wear one and
one-half times as well on the
government course as a tire graded 100. *
Traction: The traction grades, from
highest to lowest are AA, A, B, and C.
The grades represent the tire's ability to
stop on wet pavement as measured
under controlled conditions on specified
government test surfaces of asphalt and
concrete. A tire marked C may have
poor traction performance.
*
Temperature: The temperature grades
are A (the highest), B and C,
representing the tire's resistance to the
generation of heat and its ability to
dissipate heat when tested under
controlled conditions on a specified
indoor laboratory test wheel.
M.
Maximum Inflation Pressure:
Indicates the tire manufacturers'
maximum permissible pressure or the
pressure at which the maximum load
can be carried by the tire. This pressure
is normally higher than the vehicle
manufacturer's recommended cold
inflation pressure which can be found
on the Safety Compliance Certification
Label (affixed to either the door hinge
pillar, door-latch post, or the door edge
that meets the door-latch post, next to
409

the driver's seating position), or Tire
Label which is located on the B-Pillar or
the edge of the driver’
s door. The cold
inflation pressure should never be set
lower than the recommended pressure
on the vehicle label.
The tire suppliers may have additional
markings, notes or warnings such as
standard load or radial tubeless.
Additional Information Contained on
the Tire Sidewall for LT Type Tires
Note: Tire Quality Grades do not apply
to this type of tire. LT type tires have some additional
information beyond those of P type tires;
these differences are described below.
A. LT: Indicates a tire, designated by the
Tire and Rim Association, that is
intended for service on light trucks.B. Load Range and Load Inflation
Limits: Indicates the tire's load-carrying
capabilities and its inflation limits.
C.
Maximum Load Dual lb (kg) at psi
(kPa) cold: Indicates the maximum load
and tire pressure when the tire is used
as a dual, defined as four tires on the
rear axle (a total of six or more tires on
the vehicle).
D.
Maximum Load Single lb (kg) at psi
(kPa) cold: Indicates the maximum load
and tire pressure when the tire is used
as a single, defined as two tires (total)
on the rear axle.

You will find a Tire Label containing tire
inflation pressure by tire size and other
important information located on the
B-Pillar or the edge of the driver door.
Inflating Your Tires
Safe operation of your vehicle requires
that your tires are properly inflated.
Remember that a tire can lose up to half
of its air pressure without appearing flat.
Every day before you drive, check your
tires. If one looks lower than the others,
use a tire gauge to check pressure of all
tires and adjust if required.
At least once a month and before long
trips, inspect each tire and check the tire
pressure with a tire gauge (including
spare, if equipped). Inflate all tires to the
inflation pressure recommended by us.

You are strongly urged to buy a reliable
tire pressure gauge, as automatic
service station gauges may be
inaccurate. We recommend the use of
a digital or dial-type tire pressure gauge
rather than a stick-type tire pressure
gauge.
Use the recommended cold inflation
pressure for optimum tire performance
and wear. Under-inflation or
over-inflation may cause uneven
treadwear patterns.
WARNING: Under-inflation is the
most common cause of tire failures
and may result in severe tire cracking,
tread separation or blowout, with
unexpected loss of vehicle control and
increased risk of injury. Under-inflation
increases sidewall flexing and rolling
resistance, resulting in heat buildup and internal damage to the tire. It also
may result in unnecessary tire stress,
irregular wear, loss of vehicle control
and accidents. A tire can lose up to
half of its air pressure and not appear
to be flat!
Always inflate your tires to the
recommended inflation pressure even
if it is less than the maximum inflation
pressure information found on the tire.
Our recommended tire inflation pressure
is found on the Safety Compliance
Certification Label (affixed to either the
door hinge pillar, door-latch post, or the
door edge that meets the door-latch
post, next to the driver's seating
position), or Tire Label which is located
on the B-Pillar or the edge of the driver’ s
door. Failure to follow the tire pressure
recommendations can cause uneven
treadwear patterns and adversely affect
the way your vehicle handles. Maximum Inflation Pressure is the tire
manufacturer's maximum permissible
pressure and the pressure at which the
maximum load can be carried by the tire.
This pressure is normally higher than the
manufacturer’ s recommended cold
inflation pressure which can be found
on the Safety Compliance Certification
Label (affixed to either the door hinge
pillar, door-latch post, or the door edge
that meets the door-latch post, next to
the driver's seating position), or Tire
Label which is located on the B-Pillar or
the edge of the driver’ s door. The cold
inflation pressure should never be set
lower than the recommended pressure
on the Safety Compliance Certification
Label or Tire Label.
When weather temperature changes
occur, tire inflation pressures also
change. A 11°F (6°C) temperature drop
can cause a corresponding drop of 1 psi
(7 kPa)
in inflation pressure. Check your
tire pressures frequently and adjust
them to the proper pressure which can
be found on the Safety Compliance
Certification Label or Tire Label.

Corsair (CTF) Canada/United States of America, enUSA, Edition date: 202007, First-Printing Wheels and Tires

To check the pressure in your tire(s):
1. Make sure the tires are cool,
meaning they are not hot from
driving even a mile.
Note: If you are checking tire pressure
when the tire is hot, (for example, driven
more than 1 mi (1.6 km), never bleed or
reduce air pressure. The tires are hot
from driving and it is normal for
pressures to increase above
recommended cold pressures. A hot tire
at or below recommended cold inflation
pressure could be significantly
under-inflated.
Note: If you have to drive a distance to
get air for your tire(s), check and record
the tire pressure first and add the
appropriate air pressure when you get
to the pump. It is normal for tires to heat
up and the air pressure inside to go up
as you drive.
2. Remove the cap from the valve on
one tire, then firmly press the tire
gauge onto the valve and measure
the pressure. 3. Add enough air to reach the
recommended air pressure.
Note: If you overfill the tire, release air
by pressing on the metal stem in the
center of the valve. Then recheck the
pressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire,
including the spare.
Note: Some spare tires operate at a
higher inflation pressure than the other
tires. For T type mini-spare tires, see the
Dissimilar spare wheel and tire
assembly information for a description.
Store and maintain at
60 psi (4.15 bar).
For full-size and dissimilar spare tires,
see the Dissimilar spare wheel and tire
assembly information for a description.
Store and maintain at the higher of the
front and rear inflation pressure as
shown on the Tire Label. 6.
Visually inspect the tires to make
sure there are no nails or other
objects embedded that could poke
a hole in the tire and cause an air
leak.
7. Check the sidewalls to make sure there are no gouges, cuts or bulges.
Inspecting Your Tires and Wheel Valve
Stems
Periodically inspect the tire treads for
uneven or excessive wear and remove
objects such as stones, nails or glass
that may be wedged in the tread
grooves. Check the tire and valve stems
for holes, cracks, or cuts that may permit
air leakage and repair or replace the tire
and replace the valve stem. Inspect the
tire sidewalls for cracking, cuts, bruises
and other signs of damage or excessive
wear. If internal damage to the tire is
suspected, have the tire demounted and
inspected in case it needs to be repaired
or replaced. For your safety, tires that
are damaged or show signs of excessive
wear should not be used because they
are more likely to blow out or fail.

Corsair (CTF) Canada/United States of America, enUSA, Edition date: 202007, First-Printing Wheels and Tires

Improper or inadequate vehicle
maintenance can cause tires to wear
abnormally. Inspect all your tires,
including the spare, frequently, and
replace them if one or more of the
following conditions exist:
Tire Wear When the tread is worn down to one
sixteenth of an inch (2 mm), tires must
be replaced to help prevent your vehicle
from skidding and hydroplaning. Built-in
treadwear indicators, or wear bars,
which look like narrow strips of smooth
rubber across the tread will appear on
the tire when the tread is worn down to
one sixteenth of an inch (2 mm).
When the tire tread wears down to the
same height as these wear bars, the tire
is worn out and must be replaced.
Damage
Periodically inspect the tire treads and
sidewalls for damage (such as bulges in
the tread or sidewalls, cracks in the
tread groove and separation in the tread
or sidewall). If damage is observed or
suspected, have the tire inspected by a
tire professional. Tires can be damaged
during off-road use, so inspection after
off-road use is also recommended.
Age WARNING: Tires degrade over
time depending on many factors such
as weather, storage conditions, and
conditions of use (load, speed, inflation
pressure) the tires experience
throughout their lives.
In general, tires should be replaced
after six years regardless of tread
wear. However, heat caused by hot
climates or frequent high loading
conditions can accelerate the aging
process and may require tires to be
replaced more frequently.
You should replace your spare tire
when you replace the road tires or
after six years due to aging even if it
has not been used.
