The Continental Nordic Spike 700c Winter Spiked Tyre are studded tyres that are officially approved for road use. They’re available with 120 and 240 studs of hardened steel, making it possible to get out and about even in bad weather. The 120 stud version is best for riders requiring rubber contact in a straight line as the studs are only positioned in the shoulder tread areas. If clear tarmac also forms part of your winter journeys with a mix of snow, then this option may be best. The 240 studs cover the entire Nordic Spike 240 tread, and this makes this option the best choice in country areas where riders are encountering mostly soft snow and ice.
