2021 Chevrolet Traverse Tire Sizes

The 2021 Chevrolet Traverse is listed with tire sizes 255/55R20 and 255/65R18. These are the two sizes provided for this model year; the facts do not identify which size belongs to a particular trim or equipment package, so check the vehicle’s tire placard if you need the exact fitment for a specific Traverse.

In each size, the first number is the tire width in millimeters, the number after the slash is the sidewall aspect ratio, and the final number after R is the wheel diameter in inches. The two listed options differ in width, sidewall ratio, and wheel diameter, so use the size specified for your vehicle rather than choosing between them based only on appearance.

Tire fitment can vary by year or trim, and these facts do not list other model years, trim assignments, or tire-pressure ratings. Confirm the correct size and pressure for your vehicle on the door jamb or in the owner’s manual.
