A Simple Guide For Numbers on Tires | Neighborhood Tire Pros

In the realm of automobiles, where every detail matters, the enigmatic numbers on your tires often pose a puzzle even to the most experienced of us. 

Fear not, because today, we embark on a journey to demystify these numerical codes, offering you a simple guide to deciphering the language of your wheels.

Unraveling the Mystery

The sidewall of your tire holds a numerical treasure trove, revealing essential information about its size, type, and performance capabilities. Each digit serves a purpose, contributing to the safe and efficient operation of your vehicle.

Width, Aspect Ratio, and Construction

The initial digits denote the tire's width, expressed in millimeters. This is followed by the aspect ratio, representing the tire's profile height as a percentage of its width. The construction type, either radial or bias-ply, comes next, influencing your tire's performance characteristics.

Wheel Diameter

The two-digit number following the construction type signifies the diameter of the wheel in inches that the tire is designed to fit. Ensuring the right match between tire and wheel diameter is crucial for optimal performance and safety.

Load Index and Speed Rating

These two numbers at the end of the code convey the tire's load-carrying capacity and maximum speed capability, respectively. Understanding these values ensures you choose tires that align with your vehicle's specifications and intended usage.
