I have a New Holland TN-60A with 11.2R20 R1 Ag Tires on the front. I stuck a t-post through the sidewall of one last year. It still had about half tread left but the damage was so bad I figured that I'd get a new one. When I called around no one seemed to think I was telling them the right size. Most promised to call me back but never did. I was getting desperate so I decided to boot and tube the thing to get going again. I took it to a shop that did the work and I asked them about a new one. The only one they could find was in Colorado and cost $620. This is a front tire mind you... I've asked around and have never seen one cheaper than $500. Today (about a year after the original repair) the tube got a hole in it. Now no one seems to be able to even get me a tube to fit the thing. Does anyone have a secret spot where you can get these tires? New Holland is still selling them new with this size so I can't be the only one out there with this problem. A friend of mine just put a new set of 11.2R24 on his and they were only $200 each. There has to be somewhere to get these tires. Any help would be appreciated.
