What Do Tire Numbers Mean?

What do the numbers mean on your tires? You may have noticed a long string of numbers and letters printed into the rubber of each tire, and many are surprised to learn that each digit represents something different.

Tire Numbers Explained

So, what do tire numbers mean? Here’s an example to work through each digit separately. Let’s say you see the following printed on your set: P215/65R15 95H. The tire number meanings are as follows:

• P: The first letter indicates the type of car that should use the tire. In this case, it is a “P-Metric Tire” that is used for passenger vehicles. You might see “LT” for light truck tires in %%target_city_1% as well. If your tire number does not start with a letter, it is probably a European or Euro-Metric tire.
• 215: This number represents the tire width in millimeters. This tire is 215 millimeters from sidewall to sidewall.
• 65: This is the aspect ratio code, which is the height of the tire’s cross-section to the width. This tire has a height equal to 65% of its width.
• R: This tells you what kind of construction the tire uses. In this case, it is a radial construction.
• 15: This indicates the size wheel that can fit the tire. The 15 means the tire fits a 15-inch wheel.
• 95H: This stands for both the load index and speed rating. The load index of 95 highlights how much weight the tire can support from a range of 75-105, while the H represents how fast the tire can go – 130 mph in this case.

Tire Maintenance

No matter what type of tire you use on the Houston and Pearland roads, proper maintenance will keep your set in great condition for the long road ahead. Most new vehicles feature a Tire Pressure Monitoring System (TPMS) which alerts you when any single tire is under- or overinflated. You can also purchase a tire pressure gauge from an auto shop or parts department to check each tire manually!
