What Do Tire Numbers Mean?

If you’ve ever taken a closer look at your tires, you have probably noticed a code on the sidewall. If this is the case, you may be asking, “What do tire numbers mean?” Tires will feature a unique code that lets you know their size, type, and purpose. This can come in handy when shopping for new tires in the Orlando area. So, what do the numbers on tires mean? Longwood Mitsubishi discusses this more in-depth below. 

Tire Number Meaning

What do the numbers on tires mean? A tire code contains a series of letters and numbers that indicate the size, load index, speed rating, and type of tire that is necessary for your vehicle. Let’s break down the following example:

Example: P215/65R15 95H

  • P: The “P” stands for “P-Metric tire.” This type of tire is used for passenger vehicles. If your tires have “LT” instead of “P,” that indicates that the tires are designed for a “light truck.” European style tires, or Euro-Metric tires, do not have these letters, and they have different load capacities.
  • 215: 215 indicates the tire width in millimeters from sidewall to sidewall. The tire in the above example is 215 millimeters wide.
  • 65: After the forward slash comes the aspect ratio code. In our example, that number is 65. What is a tire’s ratio? It is the height of the tire’s cross-section to its width. For our above example, the height of the tire is equal to 65% of the tire’s width. The larger the aspect ratio, the larger the sidewalls. 
  • R: The “R” indicates the tire’s construction. “R” stands for radial tire.
  • 15: The next number in the code lets us know the wheel size from one end to the other. This is helpful in determining what size tire works for this particular wheel. In our example code, this particular tire fits on a 15-inch wheel.
  • 95H: The last part of the tire code is “95H.” This denotes the load index and speed rating for the tire. The load index is 95 in this example, and that figure shows how much weight the tire can support when inflated to the proper PSI. On passenger vehicles, this number can range from 75-105. “H” indicates the speed rating. The ratings are ranked from A to Z, and this letter lets drivers know how fast the tire can safely go based on its load capacity. An “H” rating in this case represents a maximum speed of 130 mph.
