What tires come on the Chevy Trailblazer?
Across the Trailblazer lineup, factory tires vary by trim and model year.

Always confirm exact specs on the door placard or build sheet for your vehicle.
Typical tire configurations by trim

- L and LS — 16-inch wheels with 205/65R16 all-season tires.
- LT — 17-inch wheels with 205/60R17 all-season tires.

Notes on tires and replacement
When replacing tires, match the original size, load index and speed rating. For everyday driving, all-season tires are common, but all-terrain tires may be preferred for frequent off-road use. Replacing tires as a set helps maintain balanced handling and performance.

Your owner's manual, the door jamb placard, and the GM build sheet provide the official tire sizes for your exact vehicle. If you have a different year or trim package, sizes may vary.
