Tire size and rear vs front hubs on 1979 ATC110

[5mman]

The '79 110 i just bought needs two tires. The guy had all the hubs off and put a new tire on one wheel. It went on the front but it turned out to be a rear hub so the front hub is on the back. Will fix but what is the difference.

Also looking at tire sizes. Anyone know what sizes will fit the back without rubbing on the guards..

I could be mistaken, but I thought all 3 rims were the same.

Stock tires are 22x11x8 on the 84's and 85's. I'd just be guessing but they're probably the same for a 79.
