If you’ve ever looked at your tires in Peachtree City or needed to order new tires from whoever gets parts for you, you’ve probably seen the numbers and letters on the tires’ sidewall. What do tire numbers mean? That alphanumeric string tells you what size and type of tires you’re using and what performance purpose they’re for. If you need new tires and are asking “what do the numbers on tires mean?” Butler Lexus of South Atlanta has all the tire number meanings for you. And if you need parts or service, the Butler Lexus of South Atlanta team is ready for you.
The tire number meanings are derived from the letters and numbers and they tell you or the service center you visit in Fayetteville your size, load index, speed rating, and type of tire your vehicle needs for best performance. Here’s an example:
Each section of the code gives you a piece of information that correctly identifies the type of tire.
“P” stands for “P-Metric tire,” meaning it’s a tire for passenger vehicles. If you see LT, that is “light truck” and if you don’t see a letter at all, that’s evidence that it’s a European-style tire with different load capacities.
After the P is the “215” number, corresponding to tire width in millimeters from sidewall to sidewall. In our example, the width of the tire is 215 millimeters.
Following the forward slash is the aspect ratio code, which is “65.” This is the ratio of the height of the tire’s cross section to its width, so in this case, “65” means the height is 65% of the tire’s width. The bigger the aspect ratio, the larger your sidewalls will be.
The “R” indicates the tire’s construction, with “R” telling you that it’s a radial tire.
“15” indicates the wheel size from one end to the other, informing us of what kind of tire can fit on the wheel. This “15” means it’s meant for a 15-inch wheel.
At the end of the code is “95H,” the load index and speed rating for the tire. The load index, or the “95,” indicates how much weight the tire can support when properly inflated. This is a range from 75 to 105 for passenger vehicles. “H” represents the speed rating, or how fast the tire can safely go based on its load capacity. This rating is ranked from A to Z, and a tire with letter “H” can hit a top speed of 130 mph.
