The mother of all studded tires! This 2.1 inch wide tire has 294 well placed carbide studs to offer you the best in ice, snow, and general winter traction. Nokian recommends this tire for all around winter riding, including mountain biking! With all those studs, big spaced out rubber knobs, and a low tire pressure, they certainly create more rolling resistance than other models, but also a lot more traction. I have a 3.5 mile ride into work. The route is mostly on bike path that is usually plowed, but not always right away. I like to ride the most when snow is falling or fresh. In situations like these, I’m usually dealing with a not plowed path, and the Extreme 294 gives the best traction. Also, because my route is slow to be plowed, the trail gets rutted up easily. Once these ruts sit for a time, they harden trough further freezing and moisture. I find that the huge number of studs helps me get through these ruts better than the other tires. They are more work to pedal, but I want traction, and these give the most! They are great for dealing with the toughest of winter commutes, and provide a great platform for riding singletrack throughout the winter.
