Skidding Protection - These Lig, thick. diagonally pliced knobs grip the slippenest road or pavement at every possible angle. They hold th,e wheel against skidding, and drive slipping” even on a wet asphalt pavement. They reach down deep into muddy or saudy roads. and hold the whfd secure where a plain tread \ouJd spill around unhindered.
