If you need new Chevy tires for your car, you may have difficulty figuring out which ones to get. This is because tires may all look very similar but have many subtle differences. This guide goes over what those various letters and numbers mean so you can make a good decision.
Tire Type
When you look at a tire, the first thing you’ll see is a letter. Chances are good that yours has a P, which stands for passenger vehicle tire. If you drive a full-size pickup truck, your tires probably have an LT, which stands for a light truck tire.
Tire Width
After the letter, you’ll see a three-digit number, which is the tire’s width in millimeters.
Aspect Ratio
The next two-digit number on the tire represents the aspect ratio. This is the height of the sidewall measured from the rim to the top of the tread, expressed as a percentage of the tire width.
Construction Type
After that, you’ll see a letter that concerns the tire's internal construction. Most tires have an R, which means that it’s a radial.
Wheel Diameter
The next two-digit number is the diameter of the wheel in inches.
Load Index
The load index is the next two-digit number, which lets you know how much weight the tire can support when inflated to its maximum air pressure rating.
Speed Rating
Finally, you’ll see another letter, which is the top speed that can be safely maintained for a sustained period. A Q, for example, has a speed rating of 99 mph.
