Hi, i currently have a b7100 hst 4x4 with turf tires on it. I would like to trade and or outright buy a set of ag tires for it. As we all know its not as simple as just switching tires, the wheels are different. So i have a complete matched set of turf tires in good shape. At least 3/4 tread life left. Front size is 20.5x8x10 rear size is 29x12.5x15. Im interested in any style ag tire preferably r1's. They do not need to be brand new im ok with them being half worn or totally shot... at least i can use the wheels to get new tires. Thanks a lot for looking im located in berks county Pennsylvania
