We have a 2007 32’ with 22.5s. I think my neighbours’ 30 and 31 foot Newmar’s do too.

Some of the larger 19.5's will carry as much or more weight then a smaller 22.5. I have driven Class A's with both sizes, and the difference in ride in my opinion was insignificant.

Please explain I have never seen a tractor trailer with a 19.5 in rim all I ever seen was 22.5 with heavy load. Rv were the only thing I ever thing Ive seen have this weird size tire rim.

I don’t know if this is the place for this question. I am a year away from upgrading from class C Ford 29 ft to 31 to 35 foot class A. The new Ford A chassis should be out by then with the bigger engine and 10 speed trans. My first question is the bigger engine going to be a V 10? Second is opinion from current owners that have had both 19.5 and 22.5 tires. I am excavating contractor and have always gone with biggest wheels possible. Problem I have is most 32 footers are 19.5 rubber ( but is my preferred size for coach. Or the 35’s with the 22.5

Thanks in advance for you opinions

I have 19.5 tires on a 33 foot motorhome with 2 slide outs and never a issue with the tires, as to weight carrying also no issue, my 6 tires carry more weight than the 20,500 lb chassis does.

Also a plus for 19.5 is you can carry a full mounted spare and they cost less..

If you are buying a new RV.. well then there is this tool you have that can get you most anything you want (Provided it is possible) including 22.5" tires.

It's called your rear end...... Exiting the door... while the bottom line looks like this: Buyer's Signature: ____________________
(notice that it's blank)

If it means getting a signature on that line.. They will find a way to give you 22.5's.. For to a salesman there is one and only one problem.. that blank line.

A 10Rx 22.5 has a load rating of 5675 lbs


I am not trying to say a 19.5 will or can carry more weight then a 22.5 tire. I am stating that on many gas chassis the option of going with a 22.5 or 19.5 tire does not have anything to do with weight carrying capacity. A 19.5 tire can safely carry the weight.

My preference would be to buy a slightly used motor home, so I wouldn't waiting to buy the new Ford model. I ended up buying a used one with the 19" tires and haven't had a problem and it works well for our traveling i.e. we're not full timers. I can see trying to get one with the 22" tires if possible, but I'd be more concerned about floor plan, quality, and cargo capacity if looking for a used unit. If buying new, I'd go for the 22" tire as long as the cargo capacity was is adequate, based upon the reputation for better ride quality with the larger tire.
