Discount Tire add on insurance

We always have the warranty - even drove directly to Discount Tire with a brand new car to buy the road hazard warranty for the tires ( does not come with brand new tires on a brand new car). I have had damage to the sidewall that could not be repaired. Something punctured the sidewall while driving. I had expensive sport tires at $160 each -- tire was replaced - no cost to me. Worth the money - you bet. We have also had tires that didn't wear like they should and because they always did the tire service and had record of rotation/balances etc the tires were replaced - again, no charge to us.
