This warranty is available for tires damaged by road hazards within the first 12 months after the purchase date, or until the first 3/32” of the tire tread wears away, whichever comes first! If this tire sustains road hazard damage (typically caused by nails, glass, or potholes) on its tread area, customers have a right to use the Road Hazard warranty for a Tire Replacement of an equivalent Kumho tire. To receive the Road Hazard warranty, customers with damaged tires must file a claim with Kumho Tires.
