1997. The other numbers are marketing codes used at the manufacturer's
discretion. 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
This number 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 conditions.
1.5.9.2. UTQGS Information
Tread wear Number
This number indicates the tire's wear rate. The higher the tread wear 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 pavement. 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 temperature 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".
