An excellent studded tire designed for smaller tire sizes, suitable for GZR Pedelec Plus folding bikes. The combination of 168 hard metal studded steel and the tire's moderate tread pattern ensures good rolling resistance and grip, especially on low snow roads. The knobs on the tire also feature a friction pattern to enhance grip in addition to the studs. The reflective side wall ensures that your winter cycling will not come as a surprise to drivers. The puncture-resistant rubber guarantees you reach your destination where a standard tire would have already been punctured by gravel. The advanced SmartGuard puncture protection of the Plus model prevents gravel from penetrating the tire and also protects against the wear of studs pushing through the tire after years of use.
