Tire Safety Information
Bri-Mar 46
where it was manufactured, and the last four numbers represent the week
and year the tire was built. For example, the numbers 3197 means the
31st week of 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.
3.5.10.2 UTQGS Information
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 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,
underinflation 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".
