My trailer lists pressure at 65 psi for the 225/75-15 load range D tires that come with the trailer.
These tires were replaced with load range E tires of the same size. Load range E tires are rated to run at 80 psi
I weighed my trailer and have just under 8,000 lbs on the axles and 1,800 lbs pin weight.
Looking at Maxxis load and inflation tables they show 45 psi at 2,020 lbs per tire.
I don't plan on running below the 65 psi listed for the original tires, I think 45 psi is too low, but I am now running a stiffer tire, so should I be running at a higher psi than 65? I think 80 psi would be too hard for the weight.

I know many people go to a higher load range tires, so I wonder about other opinions?

Thanks
