Two out of three tires burst. They are only lightly welded to one side of the axle. I have two spares and I definitely expect them to break as well. Worst of all, I had to disassemble the rear end of my chicken tractor to replace these tires. Now they want me to disassemble it again. The food is now leaking from the first time and can only get worse if I take it apart again. I can only take it apart when the food runs out. But then I expect them to break again. I was hoping to contact Waxman to find out, but Revane won't let me. Shit!
