Do you know your car’s tire size? It’s not just a number—it sets the boundaries for what tires are worth considering when you need to shop for replacements. We’ll give you the tools you need to narrow down the options and see what’s popular for your wheel diameter when you compare by tire size.
How do I find my tire size?
When you look at the sidewall of a tire, you’ll see a long series of letters and numbers that look something like this: P 215/65 R15 95H. This is a tire size number. More common wheel diameters, in the range of 16” to 20”, have more tire selections for you to compare. Review your owner’s manual for manufacturer recommendations when you start shopping for new tires for your vehicle.
