Which brand should you pick?
Chevrolet does not stamp its own approval code on tires the way Porsche or BMW do. Any tire in the right size that meets or exceeds the load index and speed rating on your door placard is a legitimate replacement, so pick on wet braking, tread life and price. Our picks for each size are on the size pages below.
Every US car built since 2003 carries this placard. It also gives the pressures, which the sidewall does not: the number molded into the tire is the maximum it can hold, not what your car wants.
