not your normal tire thread

we put Carlisle on in October of 2016 getting rid of the Lyons Head that was on our trailer from new. The LH had only about 10,000 miles on them and had one coming apart. We were in Ohio and discount had the Carlisle. I was concerned due to their previous record but they assured me they changed and the MPH and the quality changed. I did some checking before we had them put on and they did have some changes before i made the purchase. we probably have about 25,000 or more on them, back and forth in hot weather and cold. from east to west and north to south. they are still in great shape. I still plan on replacing them in october when they become 3 years old.
