Since when do slick icy roads beckon you out for a bike ride? Since you switched out the slicks for studded bike tires. A set of snow tires mounted to a spare set of wheels [and you always wanted a spare set of wheels] turns Tuesday’s blizzard into Wednesday’s wonderland. And if you want to commute by bike year-round, Nokian bike tires or the studded tires from Kenda or Continental are essential for control and confidence sharing the road. Can’t afford a set? Get one for your front wheel, which holds the majority vote whether or not you’re going down.
