This is untrue. They are designed to be safely inflated up to and including the stated maximum cold tire pressure. Pressure increase due to heat from driving is accounted for in this. It is perfectly safe to set to Max cold psi and tow all you want. The hot pressure will be higher than the stated cold max, but the tire is designed for that. If it makes you sleep better, let a few pounds out but you are actually lowering the maximum weight capacity of the tire when you do that. How much depends on the size. The Toyo tables posted are a good place to start.



What is untrue? I was giving my opinion based on almost million miles driving over the last 35 years hauling and towing.
