Continental Contact Spike 700c Wire Tire Ice and Snow, Under Control When roads turn to ice, most road and city tires become a liability. The Contact Spike is made for exactly those conditions - a studded winter clincher that keeps you moving through the cold and dark season with confidence. 120 strategically placed metal studs dig into ice and packed snow to hold traction through corners and hard stops, where an unspinned tire would give out. The Safety System Breaker, a Kevlar-reinforced high-strength nylon layer under the tread, adds flat protection without adding noticeable weight or rolling drag. A reflective sidewall stripe keeps you visible on short winter days. If you're commuting or riding year-round and want to keep rolling when everyone else parks their bike, this is the tire to mount up.
