How To Read Your Sidewall Marking on Tires?

Sidewalls of tires usually have markings that show tire information. Here are some of the information you can get.

A. Class of tire

The class of tire will be indicated on the tire wall. P stands for passenger car tires such as crossovers, SUVs. L stands for a light truck tire. This is designed for cars for towing cars. ST is for special trailers such as cars with fifth wheels, boats, and winter tires.

If the tire did not have a letter, it is in metric measurement wherein the measurement is in millimeters.

B. Section width

This is the tire’s width. Look for the number to see how wide your tires are in millimeters. In the image above, the section width is 215 millimeters (8.46 inches). How to measure the tire width? You will need to measure the distance from the sidewall edge across to the opposite side.

C. Aspect ratio

This is the tire’s height-to-width ratio and is usually indicated by a letter such as 80, 70, or 60 (80 means that it has an aspect ratio of 80%.) The higher the number, the taller your tire is. How to measure the tire sidewall height? You will need to measure the tire sidewall height from rim edge to tread face.

D. Construction Type

This indicates the type of construction inside the tire. The two most common types are radial and bias-ply. R stands for radial while B stands for bias-ply. Radial construction type means that the cords that run across the tire are at a 90-degree angle to the direction of travel. This type is usually used on modern cars. Bias-ply construction type means that the cords are at an angle less than 90 degrees and were more commonly used in older vehicles.

E. Wheel Diameter

Wheel diameter also known as wheel rim diameter indicates the tire’s outer width. It is usually measured in inches and can be found on your car owner’s manual or door jamb sticker.

F. Load Index

This number ranges from 65 to 150 which measures the load-carrying capacity of a tire when properly inflated for inflation pressure at maximum load, but should never be used as the only indicator of tire safety. Carrying too much weight on a tire can overload it and will cause sidewall failure, blowouts, or catastrophic damage. Consult your car owner’s manual to find out how much weight your vehicle can safely carry.

Here’s a table of the load capacity based on load index.

G. Speed Rating

This letter is an indication of the maximum speed that the tire is capable of. Speed ratings are A1 to (Y). Higher ratings mean a higher top speed for your car. Consult your car owner’s manual to find out what speed rating your vehicle should have.
