I’ve read the thread on wheels & Tires what to do. The chart shows 10 lug front & rear for a 1949 ton & 1/2. I’ve got ten lug on rear 5 lug up front. The attached photos show the rims.
Are these two piece locking rims (safe) or the dreaded split rims (widow makers)? Is that an adapter for the 5 lug front wheels?
The front wheels also have 10 holes- - - -the reinforcing plate just covers up half of them since there's only 5 lugs on the front hubs. Your photo doesn't show enough detail, but it appears you've got a 3-piece wheel with a small locking ring holding a full-circle bead ring in place on the front wheel. The bead ring and lock will be facing inward on the rear wheel where it can't be seen without unbolting the wheel. Any commercial truck tire shop should be able to service those wheels, as long as they're not rust-damaged enough that they don't lock together safely. They don't appear to be widowmakers. Jerry

22.5's with that bolt pattern are a direct replacement, although not common. They appear on late '50's 1.5 ton trucks, when tubeless tires first came out. Popular on farm trucks.
