Gvwr gas class A--compare 20500 vs 24000

I am looking to get class A gas coach. Looking at used and new options.

When you go to a 22 k gvwr or 24 k gvwr chassis, you end up with 22.5 inch diameter tires vs 19.5 inch diameter tires for the coaches with 20.5k gvwr and below chassis.

Anybody driven both size tires.? What is the difference when on the road?

Thanks for any input.

Out previous motorhome was on the 20,500 lb. Ford F53 chassis with the 19.5" wheels. Our current motorhome is built on the 22,000 lb. Ford F53 chassis with 22.5" wheels.

The new one rides much smoother and quieter than the previous one. I'm not sure the improvement is solely due to the tire size. Like most vehicles there have been a number of other improvements over the years.

Keep in mind however that the GCWR (Gross Combined Weight Rating) for both is 26,000 lbs. Essentially that means on the newer one you can load 22,000 lbs. on the frame, but the maximum amount you can tow (assuming the chassis is loaded to the maximum) is 4,000 lbs..

The older one can only carry 20,500 lbs. on the frame, but the maximum amount you can tow (assuming the chassis is loaded to the maximum) is 5,500 lbs.

I have had both sizes on a gas chassis. I much prefer the 22.5 tires for ride, handling and tread longevity. There is one day when the larger tires are a negative ...... tire buying day.

22.5 are preferable, except on tire buy day, as others have commented. However I would not pass on a coach that I really liked and in good condition due to having 19.5 tires. My 37' gas coach is on a 22k chassis with 19.5 tires and works fine.

Be glad you don't have our size tire ... 24.5 .... that's a harder one to find when you need to replace fast AND more expensive ....
