8 years ago I had RG in my tires, in Dec. got a puncture in one, took it back to the kubota place where I bought my tractor, they drain it, patch the tire, refilled it with RG, had to add coulpe gal of new. Sat. morning picked it up, wanted to know if it had a tube, dont think it did because the slip said (patch tire) the sales guy didn't know, tire guy wasn't there so I paid the $250.00 bill and got a thank you for your business, I was just happy to get the tire back by Sat. I think those original 11.2-24 AGs were 4 ply, I now have 6, next time I'll get 10.
If in a couple years I do have to change tires, I'll look into getting all the tools and jingle jangles of doing the job myself, if I can find a RG transfer pump that I can afford, I'll might even get that, but then again, I'm thinking of switching to and making my own external wheel weights and to hades with ballast filled tires.
