So I couldn't get the wheels off the axle. I tried with the old tires, cut those dirty birds off and tried again. Nope. I heated them with mapp gas, tried a puller, a rammer and a hammer. Still a BIG NOPE! I'm thinking about cutting the wheels off and getting new ones. That or the whole axle. I'd just get the new tires on there but I don't roll like that, I maintain my toys and if a sprocket breaks, I want disc brakes, bearings need replaced.... the wheels gotta come off! Its a rust thing, the ring retainers in the back are to keep the wheel from moving in not out so i know this isn't mechanical. Any suggestions y'all?
