Try tire town. www.tiretown.com they sell "buffed" tire which means they scrape off the name because there was some small defect with the tire when it was made. These tires are usually 1/2 the price of new ones. I just bought some rear tire for our 4850jd and save a bundle.
I have two 30.5 x 32 tires that you can buy cheap !! One is like new with less than 50 hours and the other is in good shape with some weather cracking. They came off of an International 1460 that we will not be using. I can help you with delivery or shipping. Call me I can make you a deal that you can't refuse !! 225-806-1701 any time
