I run a mobile business out of my truck. I bought these tires as replacement tires two years ago. I have put 63.000 miles on them and they still have tread. I have driven them in all weather conditions, in a lot of snow. They have perform flawlessly. Sadly I now have to replace them and at the current price I am not buying Goodyear. I rotate my tires about 7.000 miles and these SR-A's have wore well. I have never had an alignment. You can't beat these tires for performance.
