If your tires are 15" I highly recommend the GoodYear trailer tire they sell at Discount Tire. They have a speed rating of 87 mph and GoodYear will replace with new if there is a blow out down to 3/16". We had problems with several tires on our triple and after switching no problems at all. Just finished a 6K trip. I replaced the back two as they seem to wear faster than any others at $130 each. I am guessing they went somewhere between 12 and 15K and the front two axles are still fine. Just my recommendation though.
