Someone should post that the speed limit on most LT tires is only 65 MPH at the full weight rating on the tires. If you are doing 75 MPH, you need to derate the maximum weight capacity by 10% and increase the cold inflation pressure by 5 PSI. So those 4,000 pound tires are only rated at 3,600 pounds at 75 MPH.
