How important is tire size to your selection?
Some motorhomes have 22.5 tires while others have 19.5. The style, meaning price point is the same. But as I said they have different size tires. How important is that in the big selection process?

If I’m reading you right, the 22 is better and holds more weight. But the 19 has been around a long time and does fine if additional weight isn’t a factor?
This is true and for example, our old coach was well under weight for the 19.5" tires. It had a tag axle for an additional 4500 lbs. but only because it was 36ft long and on a GM P32 chassis. At the same time, pulling our Jeep put an extra ton of overload on it and only because of the GM 4L80E transmission. No problem however, except for long 6% grades in the heat of summer.
Now with our present coach and 22.5 tires, the rear is at max GVWR when loaded for travel, but because of the axle, not the tires. Still a ton to the good on the front. As for GCWR, we can pull 15K lbs and stay within specs. and just as long as it's not a trailer with hitch weight to contend with and even though the hitch rating is 1500lbs.
Many don't check any of this out before purchase and concentrate on the fireplace and big TV. Fact is and if I'm looking to buy a DP, I first look in the rear for a side radiator, while most head for the entry door for checking out said TV and fireplace. But then, that's for another topic.
