M+S
‘M+S’ or ‘M/S’ indicates that the tire has some mud and
snow capability. Most radial tires have these markings;
hence, they have some mud and snow capability.
NOTE:
If it becomes necessary to replace a tire and you feel it
is a warranty issue, most tire manufacturers require the
D.O.T. number be cut out and returned to them with the
warranty claim. Otherwise, the warranty could be voided.
U.S. DOT Tire Identification Number
This number begins with the letters “DOT” and indicates
that the tire meets all federal standards. The next two
numbers or letters are the plant code where it was manu-
factured, and the last four numbers represent the week
and year the tire was built. For example, the numbers
3197 mean the 31
st
week of 1997. The other numbers
are marketing codes used at the manufacturer’s discre-
tion. This information is used to contact consumers if a
tire defect requires a recall.
Tire Ply Composition and Materials Used
The number of plies indicates the number of layers of
rubber-coated fabric in the tire. In general, the greater
the number of plies, the more weight a tire can support.
Tire manufacturers also must indicate the materials in
the tire, which include steel, nylon, polyester, and others.
Maximum Load Rating
Load rating indicates the maximum load in kilograms and
pounds that can be carried by the tire.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that
should ever be put in the tire under normal driving condi-
tions.
Treadwear Number
This number indicates the tire’s wear rate. The higher the
treadwear number is, the longer it should take for the
tread to wear down. For example, a tire graded 400
should last twice as long as a tire graded 200.
Traction Letter
This letter indicates a tire’s ability to stop on wet pave-
ment. A higher graded tire should allow you to stop your
car on wet roads in a shorter distance than a tire with a
lower grade. Traction is graded from highest to lowest as
‘AA’, ‘A’, ‘B’, and ‘C’.
Temperature Letter
This letter indicates a tire’s resistance to heat. The tem-
perature grade is for a tire that is inflated properly and
not overloaded. Excessive speed, under inflation or
excessive loading, either separately or in combination,
can cause heat build-up and possible tire failure. From
highest to lowest, a tire’s resistance to heat is graded as
‘A’, ‘B’, or ‘C’ (see “Appendix A” for more information).

TIRE TIPS
•
Make sure all of the lug nuts are secure. Use a
torque wrench. Do not guess.
•
Inspect tires for uneven wear patterns on the
tread, for cracks, for foreign objects or for
other signs of wear or trauma.
•
Trailers should have the wheel bearings
repacked after being in storage for long peri-
ods of time.
•
Do not overload your vehicle.
•
Check the tire information placard for the
maximum recommended load for the vehicle.
Never exceed the wheel manufacturer’s rec-
ommendations.
•
It is important to maintain proper wheel nut
torque to provide safe and secure attachment
of the wheel to the hub/drum.
Tighten Each Lug Nut In The Order
Shown
Start all lug nuts by hand to prevent cross threading.
Tighten opposite sides of
the wheel; start at 1 and
go to 2, then 3 and 4, etc.

manufacturer of the wheel.
If this information differs
from the wheel manufac-
turer’s information, use the
wheel manufacturer’s recommendation.
