Optional Road Hazard Insurance must be purchased at the time of your tire purchase. All Road Hazard tire replacements are done on a "pro-rated" method (e.g.: if you hit a curb and ruin a tire that has 75% tread life remaining then you will get 75% credit towards the new tire you must purchase).
Additional cost: You will be responsible to pay for the install of the new tire (which averages $18 each) as well as the road hazard insurance on the new tire.
Flat repairs are included when you buy the road hazard insurance.
What is NOT covered by the road hazard warranty?
Tires ruined by an alignment problem
Tires worn out prematurely
Tire worn out due to under inflation
Tires more than 5 years old (from the date of purchase)
