Whether you’ve been checking the tread levels in your garage or preparing to buy new tires to replace a worn set, you may have noticed that each tire on your car has a set of numbers embossed into the rubber – so what do tire numbers mean? These numbers tell you valuable information about your tire type and size, so it’s easy to find replacements around Lebanon and Mascoutah! Let’s dive a little deeper into what do the numbers on tires mean:

Tire Number Meaning

Tire numbers may seem like a jumble of letters, numbers, and symbols on first glance. So, how do you decipher your tire number meaning? We’ll break down an example. Say you see the following on your tire: “P215/65R15 95H

  • P stands for P-Metric tire, or a tire suitable for passenger vehicles. You might also see an LT instead, which stands for “light truck”.
  • The 215 indicates the tire width in millimeters from sidewall to sidewall, or the sizing of the tire.
  • The 65 indicates the tire’s aspect ratio, or the height of its cross-section to its width. Bigger aspect ratios have bigger sidewalls.
  • R stands for radial, which offers insight into the tire construction.
  • 15 is the wheel size, so this tire is meant for a 15-inch wheel.
  • 95 is the load index, or how much weight the tire can handle when properly inflated.
  • H is thespeed rating, or how fast the tire can go. Speed ratings run from A to Z ratings, and H indicates that the tire can handle a max speed of 130 mph.
