INVESTIGATION INTO THE ACTUALLY OCCURRING PROJECTION OF THE SPIKES ABOVE THE RUBBER BEARING SURFACE OF WINTER TYRES

UNTERSUCHUNG UEBER DIE IN DER PRAXIS VORHANDENEN UEBERSTAENDE DER SPIKES UEBER DEN LAUFFLAECHENGUMMI VON WINTERREIFEN

The investigation was conducted to assess the possible reduction in road surface wear effected by the use of self-resetting spikes with a maximum projection of 2 mm. The projections of 49000 spikes on 2006 tyres were measured and a mean value of 2,054 mm was established. On 45% the projection was more than 2 mm. The projections were also classified according to the type of tyres and vehicles. In a test stand it was found that in 22% of tyres the projection was increased due to centrifugal force by more than 20% compared to the projection at rest. It was found that the use of self-resetting spikes and a legal limitation of the projections to a maximum of 2 mm the road wear could be reduced by about 50%. /TRRL/
