be sure to check and see if road hazzard is included in the purchase price or if you added it on when you bought the tires. We bought tires 2 years ago at Sams and they had road hazzard on them. The other day I ruined a tire by backing out of the drive with a flat. My own stupid fault. I took the tire back to Sams' and they didn't ask how it happened, just charged me an $11 mounting fee to replace it. I was thrilled to say the least. Be sure to check if you get a flat or ruin a tire..... . Flats fixed for free are also included in my tire package.
