1 Summer tires tend to wear faster and are more susceptible to damage from road hazards or curb impact than standard profile tires. This type of damage is not covered by the GM New Vehicle Limited Warranty. You may want to get different tires if you expect to drive in winter conditions. See your dealer for proper tire selection.
