Hi all !!! I read this forum all the time and have posted very little. I just had ankle surgery this morning so now I have 8 weeks to really bother everyone /forums/images/graemlins/laugh.gif I will be purchasing my very first tractor in the spring of 06. I have decided on A 4320, 400x loader, and A 448 backhoe. Along with A tiller, rear blade and landscape rake. Im having trouble on one thing and that is tire selection. Ive searched past post on tires and I think the R1s would be the choice but the thing that concerns me is are the R1s designed to handle the weight and stress of loader and backhoe work? I know its A stupid question. I know Rockyridge uses R1s w/hoe and loader. Any advice would be greatly appreciated. Thanks Mike
