Well I called the manufacture of the wheel on my trailer to find out what the max PSI I could I safely inflate the tires too and they wanted to know if there was a name stamped on the wheel...well I could not find anywhere on the wheel of a name the only wording I could find was Made in china. They asked if it was a steel wheel which I replied yes. After that they said was the max PSI I could safely inflate my tires to was 65 PSI due to too much stress on the weld's and (casting hole's)?...
Given that it's 1) made in China and 2) that RV mfrs use the =absolute= minimum hardware to to the job, I'd replace the wheels if you want to go to E tires. If you stay with a steel wheel rated for 80 psi, they're really not that expensive, especially if you buy a tire/wheel combo already mounted and balanced. You can sell the current ones, including the tires, and recoup more than you might think to offset the cost.
FWIW, my dad did this on a cargo trailer we have, and the tire/wheel combo was =cheaper= than replacing just the older, odd-sized tires. Same weight rating on both tires.
