What Do Tire Numbers Mean?

Tires on a shelf

Every tire comes with a combination of numbers and letters printed on the sidewall, but what do tire numbers mean? This numeric code indicates the tire’s size, type, and performance level, making it easy to find when you need new tires in Dover. Take a deeper look into tire number meaning with help from Dover Honda.

Decoding What Tire Numbers Mean

Your Portsmouth service center uses tires codes to find the right speed rating, size, load index, and overall match for your particular vehicle. Let’s break down this example:

P215/65R15 95H

Each section communicates different aspects of this tire’s performance and ideal vehicle:

P: this first letter stands for “P-Metric tire,” meaning that it is rated for passenger vehicles. Tires could also read “LT,” for “light truck,” indicating its use on light-weight pickup trucks. Tires without a preceding letter are considered European-style tires, or Euro-Metric tires, which have different load capacities.

215: this number stands for tire width in millimeters, measuring from sidewall to sidewall. In this example, the tire width is 215 millimeters.

65: this is the aspect ratio code, which is the height of the tire’s cross-section to its width. The bigger the aspect ratio, the bigger the sidewalls will be. This example tire has an aspect ratio where its height is equal to 65% of its width.

R: indicates the tire’s construction, with “R” representing that it’s a radial.

15: this number stands for wheel size, helping Rochester drivers understand what tire will fit on this wheel. This example is meant for a 15-inch wheel.

95H: the final section of the code indicates the tire’s load index and speed rating. The load index (“95” in this instance) indicates how much weight the tire can support when it’s properly inflated, and can range from 75-105 for passenger vehicles. “H” represents the speed rating, which is how fast the tire can safely go based on its load capacity. This rating is ranked from A-Z, and with our example, a tire with an “H” rating can reach a maximum speed of 130 mph.
