My sons and I have run a bunch of Maxxis over the last 6 years. They are excellent, and show an amazing lack of dry rot at 5 or more year of age. HOWEVER, they are 65 mph tires giving no margin of 66 MPH. I just put Goodyear Endurance an a utility trailer and a new fifth wheel camping trailer. I am impressed with the higher speed rating (don't remember exactly, but it is 80+ mph) which gives a margin of safety when driving at 65 mph. They are also heavier tires than other ST and LT tires in the same size. Lastly, they look good. So far, no problem, but it is early.
