I just finished my first winter with studded tires. I had the Nokian Mount and Grounds, and its been fantastic being able to ride all winter long. However, I took the M&G's off tonight and replaced them with my Michelin Country Rock tires. MAN what a relief! I didn't realize how much rolling resistance the studs have. At one time I thought that I would rather have the most aggressive studded tires I could get, like the 294's. I have changed my mind. The M&G's are a knobby with studs. If I was going to buy another set, I would get a road tire with studs. Something with low rolling resistance. I ride a bike, not a snow plow. I don't need to be able to barrel through snow drifts. I need to be able to ride down the road and not slip on the ice and fall on my butt.
Maybe next winter I'll set up my hybrid with studded road tires.
