Here is a happy ending customer service tale, could not get some R1 tires mounted, complete thread here:

UPDATE:
The tires are mounted! I can't thank tiredguy (Al) enough for sticking with me through this problem. He spent a good deal of his time & effort putting me in touch with the right people to get this solved, without the possibility of profiting from the situation. A class act, I wish we weren't so far apart, so I could take all my tire business to him.
I must also thank Adam & William from Carlisle Tire, and Rob & Jayson from S&S tire in Peoria AZ, who mounted the tires at no charge.
After many e-mails & phone calls, exchanging drawings, pics, dimensions, & technical data, the decision was made to re-try mounting the tires at an experienced, knowledgeable shop that deals with tractor, skid steer, implement & even aircraft tires on a regular basis. They sent me to S&S Tire.
Turns out the whole problem was not enough of the proper lube. S&S mounted the tires effortlessly, and explained that tires such as these need LOTS of FULL STRENGTH mounting lube, as they are just tighter & stiffer than passenger car tires and the like. I have been without the use of the tractor for almost a month, and had been envisioning all sorts of expensive, nightmare endings to this story.
I now have a much elevated opinion of Carlisle Tire, S&S Tire, and of course, tiredguy. I think from now on he is Mr tiredguy, or maybe even Sir tiredguy. Thanks again Al!
