What Do the Numbers on Tires Mean?

Tire Row

If you look at your tires up close, you’ll notice a combination of numbers and letters printed on the tire sidewall. So, what do the numbers on tires mean? The tire number meaning is actually a standardized code that tells you a lot about the size, type, and capacity of your set. So if you’re getting ready to go tire shopping around Corona, you can learn a lot from this string of letters and numbers! Find out what do tire numbers mean with BMW of Murrieta, and stop by Murrieta with any questions.

Tire Number Meaning

When you take a tire number like “P215/65R15 95H”, every letter and number means something different. Let’s break down the different components of this example:

    • P: This stands for “P-Metric tire” or a passenger vehicle tire. You might see “LT” for “light truck” or no letter at all on a Euro-Metric tire.
    • 215: This indicates the tire width in millimeters from sidewall to sidewall, or 215 millimeters in this case.
    • 65: This gives the ratio of the tire height of the tire’s cross-section compared to its width. In this case, the tire’s height is 65% of its width. It tells you how thick the sidewall is.
    • R: This means the tire has a “radial” construction.
    • 15: This means the wheel size from one end to the other, so this is a tire meant for a 15-inch wheel.
    • 95: This is the load index, which tells you how much weight the tire can support. This figure ranges from 75 to 105, and our example tire is 95.
    • H: This is the speed rating, or how fast the tire can safely go, rated from A to Z. A tire with an “H” rating can reach a maximum speed of 130 mph on the Riverside roads.
