Load rating running 72 psi in Maxxis 8008 225/75/15 E's
I know max load of 2830 is at 80psi, what would be the load rating at 72 psi? thank you

- Why? ST tires really need to be set to the Max PSI as listed on their sidewall. Heat buildup at lower pressure will kill them far sooner than necessary.

The manufacturers know nothing about what they do.- You can do the math for 72psi
PSI 25 30 35 40 45 50 55 60 65 70 75 80
ST225/75R15 1430 1600 1760(B) 1880 2020 2150(C) 2270 2380 2540(D) 2620 2720 2830(E) - About 2670+/-
- From Maxxis regarding inflation pressure. According to them, running at less than 80psi does not hurt them. I will however be running them at 80, I called and determined that my wheels were capable of 80psi.
Your inflation pressure should be determined by your maximum loaded weight. If you know what that is you can check here to determine the proper inflation:

Inflating a tire to less than it's maximum will not effect the tire's durability or performance.
Thanks for you inquiry and recent purchase of Maxxis Tires.

Usually because ST tires are loaded close to their maximum weight allowance and have a lot of sideways scuffing during tight turns with dual axle trailers. Cars, trucks, and single axle trailers don't have that problem.
I would have no problem running auto tires on a single axle trailer and, in fact, do exactly that on my utility trailer and boat trailer. I have been running my travel trailers ST trailer tires at the sidewall maximum for years and have never had a single tire problem.(Knock on wood!)

I was around years ago when Goodyear and Carlisle both didn't give a max sidewall pressure recommendation. Both have since learned from their customers experiences what worked best and what should have worked. Both now recommend max pressures.
IMO Maxxis will in time learn also.
