Actually zippy1 I'm an old dairy farm boy and I do like TRI-RIB tires. It's the multi rib V-61's that I don't care for on the tractor front. Now on a hay wagon, or forage wagon, or a gravity wagon, ( or airplane ) their fine! the multi rib's don't drag alot of mud & dirt out of the field and on to the road like regular treaded tires do. OK ?
