Rubena winter tyres offer the highest quality of spikes. The carbide tips in an aluminium body ensure the lowest possible weight and the highest wear resistance. The spikes can last several thousands of kilometres. The tips get gently abraded and slightly pushed into the tread knobs while riding but this has no influence on either the riding comfort or the spike performance. It is recommended that new tyres are allowed a 40-50km “bedding in“ period in order to allow the spikes to settle in their housings. No heavy braking or aggressive riding should be performed during this time.
