I purchased a set of mastercraft avengers about 2 years before selling my old Classic and they were exceptional on that rig. My new one has mastercraft avengers on them and I have had no issue with these either. You have had cooper cobras for 7 years with no issue and the Mastercraft avengers are supposedly the same tire. Give the avengers a shot and you should be satisfied. I feel that 6 years is as long as anyone should ever go with a tire no matter how good they look. I made 6 years on both of my first sets on the old classic and after that they started leaking air through tiny cracks in the tread that I couldnt even see. Its probably best to go no more than 5 years to be honest. The Mastercraft Avengers are a good looking tire too and they are reasonably priced.Chris CoupelPaulina, La.Chris CoupelPaulina, La.
