Changing tire size on class A

So my coach has 235/80/22.5 tires on it now. I called local tire place that does big truck and Rv tires and they suggested changing to the Toyo M154 245/75/22.5. They said it is basically the same size and has the same load rating as my tires do now. What’s everyone’s thoughts on changing size and also anyone have the m154 and how do you like them ??
Thanks

Class A

Yup, no problem, as long as the 235/80 had sufficient carrying capacity for your actual weight, suspect the 245/75 will be just fine.

The difference is about .16" - which is insignificant. In fact, there's that much variation between brands of the same size.
I think it would be fine.

Don't know about changing sizes, or your size in particular, but we have 19.5 Toyo tires on our coach and have been very pleased. We have had them almost 7 years, so will be replacing due to age, but they look very good yet. No sidewall cracking, lots of tread etc. We do keep them covered when we are parked for more than a couple of weeks.
