Lots of things are possible. It could snow in June in Arizona but its not very likely. A better question would be 'Would it be probable or would you expect that placing a "better" tire to do harm to axle and/or suspension?
To the "probable" or "expectation" question, my answer is no. If someone disagrees, I would really be interested in seeing their data that supports the idea that a tire with say 250# more load capacity and 10 mph faster max speed rating would do damage to the rest of the RV.
The only exception might relate to the wheel's max inflation rating vs the inflation the owner used, but in that cast the inflation level is not the "fault" of the tire itself.
