I hit a 6 point pitch fork at 70mph in my 7000 lb Suburban on my left front tire. I thought for sure that my tire was destroyed but to my surprise no visible damage! However the tire shot the fork back and into the driver side running board through double wall very tough plastic. It took a lot of work hammering the fork out of my truck with a one pound ball pein. I managed to drive 20 miles to a tire shop and only dropped my tire pressure from 65 to 55. The tire was toast but only due to 3 closely spaced tiny holes which made it irrepairable but had barely penetrated the tire! I will NEVER buy any other tire except BFG for my Sub!
