10 hole 22.5 inch wheels for an 18 wheeler can be redrilled to fit your 10 hole bolt pattern by shifting the bolt holes a few degrees. Those wheels will fit over the brake drums, and the 22.5 tubeless tires will be tall enough to look right. The19.5s are low profile, and will look ridiculously small on your truck, even if they would fit over the drums. Ed Pruss has posted pictures of the 10 hole big rig wheels that he's drilled to the smaller 10 hole lug pattern.
