Pedal tractors look good. I'll try to post some pics of the ones my son has (he's a little big for them now
). How'd you put the tires on? We boiled them and then wrestled them on with plenty of dish detergent. I think I had a small sheet of plywood with a threaded rod or something to secure the rim. Used welding gloves and oven mitts to handle the tires. It seems the ones on front and the trailer were hardest to install.
