This is the same as I run mine even though I have now changed from factory wheels to Hi-Spec wheels on account cracked 2 wheels. The factory wheels are 110 psi but the weight rating is 3750 pounds. The weight rating on Sailun 235x85x16 tires are 4400 pounds at 110 psi. I have proven the tires are stronger than the wheels. To get the full benefit of the tires you need to run at full pressure even though some run there tires a little less for a slightly better ride. As for as 7,000# or 8,000# axles from Mor-Ryde I think it's better to wait till Mor-Ryde weighs the rv so a person can make a decision based on your maximum gross weight. One of the purpose's of the I.S. is ride quality and even though 8,000# axles may ride better than factory ,why pay more for a harsher ride if not needed. If a customer looks at both axles they will be impressed with either compared to the factory set-up .
