275/70R22.5 vs 295/75R22.5
Currently have Sumitomo 275/70R22.5 which matches the coaches original tire spec. Getting ready to replace but having hard time finding the Sumo's. Looking at Toyo and they do not seem to have the 2...

We went from 275/70s to 11R-22.5s.
The 11Rs are the same height as the 295s, slightly skinnier so they fit our rims. 295s were too wide.
In our case I always felt we were over geared for the 275s, it just turned too many RPM at highway speeds.
With the 11Rs it's just about perfect. There hasn't been any downside - none.
Next year we'll be looking at tires again (age) and we'll definitely be doing the 11Rs again.
All that said, what engine/transmission combo are you running and what is your highway speeds RPM?
What we did may not be the best choice for you.
