P225/40R18 front and P255/35R18 rear summer, blackwall, run-flat tires

These 18" run-flat performance tires1 are optimized for summer driving on dry and wet pavements and are designed to provide low noise levels.

1 Summer-only 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.
