Diffrent coaches, different lengths, different weights, different wheel sizes - will all make a difference on the tire options, and appropriate PSI.
I have the 40' Allure with ISL, and 8.25" rims. I looked at going to 315/80 22.5 on the steers. But after seeing that they were slight derated for the 8.25", decided to go with the 295/80 22.5 instead of the 12R's. Primary reason was the 295/80 brought XZA2's into the mix for me. I had been running the last 6-7 years on XZE*'s 12R's - that I felt were a very safe and robust tire. I did lose two to pot holes in California last year during the Michelin shortage o 2015. Ended up with 2 BF Goodrich ST230's, that being new, I place on my steers. They rod a bit softer then the thick/stiff side walls of the XZE*'s. When I went shopping to replace the other 6 tires before going you on this years travels, as mentioned, I went with the XZA2's in 295/80. Put the 12R BF Goodrich ST230's on the Tag. IMO, the XZA2's ride even better on the steers then the ST230's. So far, very pleased.
I'll probably weigh a few thousand pounds less then other coaches mentioned in this thread, and my four corner weights has me safely running 100 PSI in the Steers, and 90 in the Drive and Tag - though for even more contingency, I usually run 105 PSI Steers, and 95 Drive and Tag.
I came very close to buying some used 9" rims for the Steers, to go with the 315/80 and not having to derate them, and also not have them running a bit fatter as they would on 8.25's. But looking at my coaches weight, the 295/80 were more then robust enough to cover my loads, with ease...
Just info sharing with my post, in case someone else is research tire options, especially if they want to shift from the 12R's to open up other options as far as tire models.
Travel safe, have fun, and best to all,
