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?

The 22.5's are typically on the higher GVWR chassis... An increase CCC is not unusual and perhaps a bit better handling as well.

Not sure I understand when you say the style and price point is the same. Typically entry level units on lighter chassis have the 19.5's. As you get a little bigger and a little higher up the food chain you'll see 22.5. Technically/functionally they provide greater capacity. As a bonus they seem to have better road manners than the 19.5's.

It was between the Coachmen Mirada and Entegra Vision XL. The Vision XL is the 22.5.

I would never consider the 19.5s, they won't handle the weight capacity for a true Class A.

The Ford F53 chassis was only built for one purpose - "true Class A motorhomes", and for YEARS the 19.5 was the only tire size offered. [emoticon]

As to the OPs question, bigger is always better.

As others have hinted at, it depends on how important the GVWR (Gross Vehicle Weight Rating) and the GCWR (Gross Combined Weight Rating) are to you, as well as the purchase price. In general, similar vehicles with larger wheels/tires will cost more money and have higher weight ratings. See the specifications for each chassis to confirm BEFORE YOU BUY. Google "GVWR" and "GCWR" for exact definitions. IMO, these ratings are some of the more important criteria in your prepurchase selection process.

I've never seen a motorhome that didn't have adequate wheels and tires for the chassis it was on. Thing to watch out for is CCC and GCWR, which many fail in miserably and for a number of reasons.
Axles capacity for one and most importantly for the latter, the transmission.
Having said all that, the larger wheels could very well account for more CCC and GVWR. Apples to Apples, I'd go with the 22.5's.

yep, my three motorhomes were Class A and all on 19.5s. when I was interested in moving to 22s I priced the out and there was as large differential, don't know where the price points were the same.

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?
