Who sells Alliance Tractor tires? I can't find a dealer. I am in Texas if that helps. I've seen pictures of the new Alliance R-1 tires. I need 2 for the front in 7-16, I also need one for the rear in 12.4-24 / 11-24. Not sure why the tire has two sizes on it but that is what it shows. I have one almost new on the rear so I am trying to get 3 more to match it.
