The Champ used 8.00 by 4s, but they had cabel operated brakes. Actually I think a lot of old planes used them. I can't remember offhand if the t-cart I used to fly had 'em or not. It doesn't matter so much what they came off of. Many planes used off the shelf wheel parts. What you need to find out is what model of wheels you have. The rubber doughnut model was a goodyear design I think. Don;t know who did the cabel breaks on the champ. I hear people talk about putting a "Cleveland conversion" on cubs. That may be what you have. Is there a manufacturer's mark on them anywhere? have you looked at the exploded diagrams in places like the Aircraft Spruce catalog to see if it looks like what you've got?
