How to Find Your Tire Size
Finding your tire size is easy once you know where to look. Your tire size is a combination of numbers and letters that indicates the tire's width, aspect ratio, construction type, and rim diameter.
Where to Find Your Tire Size
Option 1: Check Your Current Tires
Look at the sidewall of your current tires. The tire size is printed on the side and follows a standard format like: 205/55R16
Option 2: Check Your Vehicle
Check the driver's side door jamb. Open your driver's side door and look for a sticker on the door edge or door post.
Check your owner's manual. The recommended tire size for your vehicle can be found in the maintenance or specifications section.
Check inside your glove box or fuel door. Some vehicles have tire information stickers in these locations.
