Tire Speed Rating Codes
•
Speed Rating
- The speed rating denotes the speed
at which a tire is designed to be driven for extended
periods of time.
This does not indicate that the vehicle
or rims can safely reach or maintain that speed.
These
ratings are listed to the right. (The markings on the
example tire diagram show M. The markings on your
tire may differ.) Note: You may not find this information
on all tires because it is not required by law.
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 Permissible inflation Pressure
•
- This
number is the greatest amount of air pressure that
should ever be put in the tire under normal driving
conditions.
