Reading Tire Size Numbers & Symbols

So, what do the numbers on tires mean? Each tire has a code embedded into the surface to let you know vital information at a glance. But learning the tire number meaning can be a little confusing if you’re unfamiliar with the code. Let’s use “P215/65R15 95H” as an example:

  • P: The “P” indicates a “P-Metric tire” or one used for passenger vehicles. You might see “LT” for “light truck” or no letters at all, which indicates a European style or Euro-Metric tire.
  • 215: The “215” represents the tire width in millimeters from sidewall to sidewall, so 215 millimeters total.
  • 65: The “65” is the aspect ratio code or the height of the tire’s cross-section to its width. This tire has a height that is equal to 65% of the tire’s width.
  • R: This letter represents the tire’s construction, so “R” stands for “radial.”
  • 15: The “15” means the wheel size, so this tire is made for a 15-inch wheel.
  • 95H: This represents the load index and speed rating. The load index of “95” shows how much weight the tire can support, while the “H” represents how fast the tire can go from a range of A to Z. This tire can reach a maximum speed of 130 mph in Rochester.
