Nope, my tires are rated for the speed and load. All brand new Michelins on the TT and TV. (In Canada I obeyed the local speed limits, about 65 mph on the highway).

In May I traveled from Goodyear, AZ (17 miles west of Phoenix) to Denver, CO, 900 miles by all Interstate. Then in late September returned going through the CO mountains over several Mt. Passes like Wolf Creek (about 11,000') with a short side trip to Farminington, NM FMCA Rally. About the same number of miles. I pulled with a 2015 HD 3/4T GMC Duramax with a loaded bed & 34' 2000 A/S Excella weighing approx. 11,000 lbs. Speed ranged between 60 & 65 MPH with target MPH at 62. Although, the dash MPH for both trip legs said I averaged 46MPH. Tires were 15" Maxxis at 60 lbs. (should have been at 65lbs). High cross winds on first leg of trip & normal weather on return. Using a Pro Pride Hitch 1400 lb bars. which is worth every penny . 2 passengers & all of what Mama could carry back & forth!! Temperatures ranged from 26* to 95 *. MPG, surprisingly on both legs of the trip, was 13.2. This truck is a Beast. There seems like nothing it can't haul. Hope this helps .TerryG above I believe was right on with his Duramax MPG.
