[AT] rear rim repair

[John Hall]

  What success have you guys had in welding up/in patches where the 
valve stem goes on rear tractor tires. The hole for the stem is about 
3x's what it should be. I also have some cracks. FWIW this is a rear 
tire on a 4020 Deere, full of fluid, and we do heavy pulling with the 
tractor--I'm guessing that is what caused the leak to develop today. All 
I know is its sweating enough to actually run water out of the valve 
stem area.
