Finding Your Tire Size

First, it's best to tackle the nitty gritty before reviewing more about each symbol. To find out what your size code is, take a look at the tire's sidewall. You should notice a collection of numbers and letters, separated by a slash-this is your tire size!

If you still can't locate the number, check your owner's manual or your driver's side door jamb to see if the code can be found there.

Your Tire Design

The first identifier you'll notice on your tire is a P or a LT. Depending on the type of vehicle you drive, this symbol will differ. If you're riding behind the wheel of a sedan, you'll see a P, which simply means that your tires are equipped for a passenger-style car.

Similarly, if a LT is depicted on the sidewall, your tire is meant for a light truck or a vehicle that can pull heavy cargo.

Your Tire's Width

Following your car's construction type, you'll be presented with a three-digit number. Quite simply, this is the measurement of your tire's width in millimeters.

So, if you see 235, this signifies that the width of your vehicle's tire is 235 millimeters from one sidewall to the other. While the width reading is different for every passenger automobile, most tend to fall within the range of 215 to 250 millimeters.

Aspect Ratio Calculation

Moving down the tire size code, you'll next see a slash and a two-digit number. Known as your tire's aspect ratio, symbol is a calculation of the sidewall height and the tire's width.

With that in mind, if your tires have a 40 after the slash, that means that the distance from the edge of your tire to the wheel rim is 40% of the width.

Wheel Diameter and Tread Structure

The last letter you'll notice in the tire sequence is an R. Since the majority of tires have a radial tread construction, it's likely that yours will be the same. The R simply signifies that the layers of your tire run across in a radial pattern, which helps reduce friction and provide cushioning on the road.

Wheels come in various sizes, which is why it's essential to know the diameter of your wheel before purchasing new tires. The final figure on the code marks the size of the wheel in inches. To ensure that you choose the right tires, you'll want to look carefully at this number.
