1 Lower profile tires wear faster. Wheel and tire damage may occur on rough or damaged roads or from surfaces or from curbs, debris or obstacles. Do not use summer-only tires in winter conditions, as it would adversely affect vehicle safety, performance and durability. Use only GM-approved tire and wheel combinations. Unapproved combinations may change the vehicle's performance characteristics. For important tire and wheel information, go to or see your dealer.
