Choosing the right car tires can sometimes feel like deciphering a secret code. But fear not, understanding the car tire size chart is simpler than it seems. When you glance at your tires, you’ll see something like this: P215/65R15. Let’s break down those numbers and letters in plain language.

That first letter, “P,” tells you these tires are for regular cars and SUVs. If you spot “LT” instead, those are for trucks or SUVs built for heavy loads. The three-digit number after the letter is the tire’s width in millimeters, so 215 means the tire is 215 millimeters wide. This affects how much tire touches the road, affecting grip and handling.

After the slash, you’ll see two digits, like 65. That’s the aspect ratio, representing the tire’s sidewall height as a percentage of its width. In this case, it’s 65% of 215 millimeters. Lower aspect ratios usually mean better handling but a firmer ride.

The “R” stands for radial construction, which is standard these days. Radial tires have layers of fabric cords that run from the center to the edges, giving stability and comfort.

Lastly, that last number, like 15, tells you the wheel diameter in inches that the tire fits. Matching the tire size to the wheel size ensures a proper fit and ride.
