Determining Tire Number Meanings

So, what do tire numbers mean? Understanding the letters and numbers on your tires might feel like solving a puzzle, but breaking it down can give you useful info. Let’s take a tire with the label P215/65R15 95H as an example and figure out what those numbers mean.

Tire Number Meaning Example

Decoding “P”: The initial letter, “P,” categorizes the tire as a “P-Metric tire,” suitable for passenger vehicles.
Decoding “215”: Numeric values like “215” indicate the tire’s width in millimeters, providing a precise measurement from one sidewall to the other.
Decoding “65”: The number following the slash represents the aspect ratio, signifying the cross-sectional height as a percentage of the tire’s width.
Decoding “R”: The “R” denotes radial construction, a common type offering stability and durability.
Decoding “15”: The final numeric value specifies the wheel size by revealing the wheel’s diameter in inches.
Decoding “95H”: The last alphanumeric sequence unveils the load index and speed rating. “95” indicates the load capacity, while “H” represents the safe maximum speed.

Knowing what each part of the tire number means helps you make smart decisions when it’s time to replace your tires.
