Discount Tire add on insurance

Always bought them for the trailer tires because with dual axles I didn't know if one went flat before it shredded. (And they ALWAYS paid off) I now have a tmps system so i'm,not sure when i have to replace these factory ones. I never bought them for the truck, or so I thought. Even my buddy at America's Tire thought I never had, but when my tire shredded last week and I went in to buy a new set (probably 3 months early), he happened to notice I had them. We were BOTH shocked but pleased. I figured with the weight of the 5th, if i'm on the freeway like I was, if i get a flat it will probably shred before i can get over and stop. So far it has always been a good deal for me, and i'm usually anti-extended warranty type of guy. Also because we are fulltiming it probably changes the probabilities!
