Look around on farm trucks in your neighborhood for 22.5's, then you won't have to fool with split rims anymore. Started in late '50's on 1.5 ton trucks.

The problem is I have already spent a good deal on new 20 inch tires for these wheels. Also I really don't know of any 1.5 ton trucks from that era that are around here. The farmers for many years have used either semis or trucks made from stretched semi tractors with a 3rd tag axle installed along with a large box and hoist. My 20 inch AR wheels aren't in too bad shape and seem to still be useable for my purposes which will be occasional driving short distances and probably not hauling too much. Thanks for the info however. Like I said above good discussion with a lot of good info.
