Nissan Sentra Owners Manual: Tire labeling

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. The TIN can be used to identify the tire in case of a recall.

Tire size (example: P215/65R15


95H) Tire size (example: P215/65R15

  1. P: The “P” indicates the tire is designed for passenger vehicles (not all tires have this information).
  2. Three-digit number (215): This number gives the width in millimeters of the tire from sidewall edge to sidewall edge.
  3. Two-digit number (65): This number, known as the aspect ratio, gives the tire’s ratio of height to width.
  4. R: The “R” stands for radial.
  5. Two-digit number (15): This number is the wheel or rim diameter in inches.
  6. Two- or three-digit number (95): This number is the tire’s load index. It is a measurement of how much weight each tire can support. You may not find this information on all tires because it is not required by law.
  7. H: Tire speed rating. You should not drive the vehicle faster than the tire speed rating.
