Help me out here. Our three previous coaches have had the 19.5. We are thinking of trading out of our current 2016 Winne Sunstar. We loved our 08' Sightseer 35J and that had 19.5 tires. We are looking at a 11' Sightseer 35J and it has 22.5 tires. Aside from being substantially more expensive to replace is the ride really that much better? Other choices for the next coach are 2004 Holiday Rambler Vacationer 37PCT or a 1999 Holiday Rambler Imperial. Oddly the Imperial looks to have 15" tires and the Vacationer has 19.5.Our 2011 Yukon XL has bigger tires than our 2000 Yukon XL did and the ride of the 2000 was much better so I must be missing something. Thanks!

I didn’t notice a difference in ride between 19.5 and 22.5. Lots of other items where I’m more concerned. Seems trivial.

Totally different ride. Also less RPM equals less wear. https://www.ntwonline.com/revolutions-per-mile-chart

The Mfg of the MH wouldn't have gone to the expense to put them on if they weren't needed to carry the weight.Bill

Larger size = higher load range. The Sightseer must be heavier and carry more cargo.

They were an option. 19.5 was standard.

ride has more to do with suspension
than it does tire size
but those 22.5 will go many miles with less wear
we went from a 95 Dp Safari with 22.5
to 97 Bounder on F53 chassis with 16" wheels

and i think the bounder rides better

Most motorhomes have room for a full 19.5 spare tire and rim, that helps with a flat issue without waiting all day for a tow service.

Without modifying the suspension, (lowering it) as an option for a given chassis, the larger tire/wheel size will significantly raise the center of gravity versus the 19.5" tire/wheels.
