Tire Information

Understanding Tire Markings

Federal law requires tire manufacturers to place standardized information on the sidewall of all tires.
This information identifies and describes the fundamental characteristics of the tire and also provides
the tire identification number (TIN) for safety standard certification and in case of a recall.
1. Tire category
P indicates that the tire is for passenger vehicles. HL indicates that the tire is a high-load rated tire.
Note: May not be shown on some tires.
2. Tire width
This three-digit number gives the width in millimeters of the tire from sidewall edge to sidewall edge.
So, if a tire is marked P245/35R21, the tire width is 245 mm.
3. Aspect ratio
This two-digit number, also known as the profile, gives the sidewall height as a percentage of the tire
width. So, if the tire width is 245 mm, and the aspect ratio is 35, the sidewall height will be 85.75 mm.
