Reading A Tire Sidewall
A tire’s sidewall is simply the outer and inner “walls” on the sides of a tire, if facing a tire on its side. Every sidewall has its own unique information that is divided into three main sections:
1. Tire Specifications
This describes the fundamental characteristics of your tire. Size, construction, speed rating and more.
2. Department of Transportation Safety Code
This assures that your tire complies with all Department of Transportation (DOT) safety standards. After the DOT insignia is your tire’s identification number, which begins with the tire’s manufacturer and plant code where the tire was manufactured (two numbers or letters). The ninth and tenth characters tell the week the tire was manufactured. The final number(s) signifies the year the tire was manufactured.
3. UTQG Code
The Uniform Tire Quality Grading (UTQG) was established by the National Highway Traffic Safety Administration (NHTSA) to test tires following government prescribed test methods and then grade each tire on three main components:
Some tires have unique benefits, as showcased with specific icons. For example, the letters M and S (M +S) indicate that the tire meets the Rubber Manufacturers Association’s standards for a mud and snow tire. The letters can be found in the following combinations M+S, M/S, and M&S. All-season tires carry this mark.
