I can say that I have experience with the turf tires and a little with the R-4's. My other tractor had turf tires and they were great in the winter and on the lawn. The biggest down fall to turf tires is they load up with mud in the summer, then there useless. I chose R-4's for my new tractor for that main reason. Now I'm still unsure as too how it will be this winter, but I don't really foresee a problem.
