I do what you do. I mow 3 acres of yard, and blow 2 drives with my NH T1510. One is stone, one is blacktop. I had R-4's and switched to loaded turfs. Best thing I did. The turfs are MUCH easier on the yard, and, to my surprise, are better in moderate snow, especially on the paved drive. The R-4 tires would not back up on the blacktop. They would spin. I use a blower, so 2 inches or 2 feet, all the same. I suppose on ice, neither would be good. Just my opinion, good luck.
By the way, for me, turfs were cheaper........
