Hey John,
I can hear the air leak at the rim so I know exactly where it is. I can pump it up and hear it pretty easy...and the next day it looks like a "run flat" tire. The reason I said what I did about this tire shop, is because they dismounted and mounted some tires for me...and the machine dug in to the inside of the rim so bad, it chunked out steel where the 4 teeth grabbed the inside diameter of the rim. Then it's the same old argument...."Well...it's just a tractor tire and wheel...you have to expect things like that on a tractor!" and you never win.
I'm gonna try to break the bead tomorrow and look at the tire and rim and then I can tell...hopefully.
