How to Read Your Tire Size

Ever wondered what all those numbers and letters on your tire mean? You're not alone! Check out this helpful graphic to learn how to decode important details about your tire’s size, construction, and performance from the set of numbers and letters. Knowing this can be a game-changer when it comes to tire maintenance, replacements, and ensuring your vehicle is running safely and efficiently. Here’s a quick breakdown of what these numbers and letters mean, so you know exactly what to look for when checking or replacing your tires:

• Tire Width: The width of the tire in millimeters from sidewall to sidewall.

• Aspect Ratio: The height of the tire’s sidewall as a percentage of its width (e.g., 55 means the height is 55% of the width).

• Construction Type: The type of tire build, like R for radial (most common).

• Rim Diameter: The size of the wheel the tire fits, measured in inches.

• Load Rating: The maximum weight the tire can safely carry. A higher number means a stronger tire.

• Speed Rating: The maximum safe speed for the tire, shown as a letter (e.g., H = 130 mph).
