The Kumho WinterCraft WS71 uses a cold-weather rubber and a V-shaped winter directional tread to create traction on packed snow and slush. The WS71 is engineered to drain water and slush thanks to the grooves on the tread, which run from the centre to the outer edge. High density 3D sipe technology provides an edge to snow biting, as the sipe is engaged by the snow and provides traction. The rubber is designed to remain flexible in lower temperatures and the outer edge of the tread is designed with a stiffer block to provide support when driving an SUV.
WS71s have 3PMSF and M+S on the sidewalls, meaning the WS71s passed the snow traction test and are marked for mud and snow respectively. The directional tread has a fitting direction indicated on the sidewall, meaning the V-grooves are to face the front of the vehicle. Tyres.co.uk sells the Kumho WinterCraft WS71.
