Beast54,
Maybe I can help clear a few things up for you.
The 19.5" wheels and tires are tubeless type.
The 20" wheels and tires are ALL tube type.
The 22.5" Wheels and tires are tubeless and are the replacements for the 20" tube type.
All three of these wheels could have the 5/10 lug bolt pattern, but they may not have the same size center hole.
When looking for the comparable tires between 20 and 22.5, the 22.5 will be one size bigger than the 20. So your 9R 22.5 will match 8.25R 20 and a 10R 22.5 will match a 9R 20.
Hope this helps...
Mike B
