I just put 6 new Firestone truck tires 1100 22.5 on my Imperial. It had 10 year old Goodyear "RV"295 75 22.5 on it and it rode and handled really well.
The dreaded truck tires ride and handle just as nice or in my opinion alot better. They were a better price as well.
Over thirty years of buying and wearing out all makes of truck tires including the low profile sizes I have never really noticed a huge difference. Unless you compare a Michelin to a Sailun or like. I always liked Michelin but have ran all the other main brands with success as well.
Depending what kind of suspension your coach has, mine has 8 airbags, you probably can't even feel if you have a flat or not.
Dropping the extra bucks on Michelin's that you will never wear out, does not make any sense to me considering they have their problems like every other brand. Just my 2 cents.
