I just put a set on my trailer also. Made a 3500 mile trip to Palm Springs and back, 104 was the highest temperature I saw, but I'm sure it was hotter on the pavement. The tires performed flawlessly and look just like they did when I left. I also had mine balanced and noticed no shake or movement that unbalanced tires would transmit through the hitch. I also stepped up to 225/75/15 load range E which is overkill for my trailer, but I would rather be over tired than not. I would recommend them Highly and think Carlisle is back bigtime in the trailer tire market!:B
Happy towing!
