I purchased my first set of TripleTred tires for my wife's SUV because she commutes 43 miles each way to work, and in our climate, it is often in the rain. These tires impressed me from the beginning with how well they handled rain-soaked freeways and backroads. Over the years we owned that set, we took trips across the country on several occasions, winter and summer. These tires handled changing weather conditions with aplomb. When they finally wore down and we needed to replace, them, I purchased our second set from the same place I purchased our first set. I don't remember what the original warranty was, but we got 97K miles our of our first set. I did pay attention to the treadlife warranty on the new set and it is 80K miles. Based on our experience with the first set, I fully expect this set to deliver similar performance and treadlife. I expect the TripleTred will be the only tires we will use from now on - they are that exceptional.
