Thanks for everyones input, Duro was quick to offer 4 free like for like tires, and did offer to Sell me an upgrade to their radial tire. But the mount and balance was a my cost. Considering the premature failure of the original tires, just don't want to the risk a repetitve occurance. Saving a few hundred $$ to use a product I don't have any faith is simply not worth the gamble with my TT, Truck and well being. Having a name brand set installed tomorrow
