The wide 5 "artillery" wheels have so many rivets I believe you would have to have some pretty nice original wheels to not have a slow leak some where. I recently went tubeless on my 52 willys army jeep. I had very good, not rusty, original wheels. I had them sand blasted, then while they were naked I brushed epoxy primer around each rivet to make sure it got good penetration , then after spraying the whole wheel with epoxy I went around each rivet with silly cone, and used a rim lube to mount and seal the beads, and....no leaks after a year.
