The speed rating denotes the speed at which a tire is designed to be driven for ex-

U.S. DOT Tire Identification Number
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 where it was manufactured, and the
last four numbers represent the week and year the tire was built. For example, the num-
bers 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 manu-
facturers also must indicate the materials in the tire, which include steel, nylon, polyester,
and others.
