Nankang Winter Activa SV-3

The directional tread pattern and the transverse grooves extending from the center rib to the tire shoulder improve water drainage when driving on wet roads by directing water from the center via the transverse grooves to both sides of the tires. Another feature is increased traction on icy and snowy roads, as ice or snow remains in the grooves and is more easily evacuated. The transverse groove connecting the irregular longitudinal groove pattern (from narrow to wide) can reduce any noise that may be generated. The undulating pattern on the bottom of the wider groove improves water drainage and provides space for ice and snow retention. Interlinked longitudinal grooves provide improved water drainage when driving on wet roads. The wave pattern on the groove bottom provides traction on ice and snow and creates the necessary frictional force with the ground. The triangular block on the inner wall of the longitudinal groove improves water drainage and traction when driving on wet roads. The sawtooth-shaped lateral grooves on the tire shoulder lead to additional frictional forces and increased grip when cornering. The grooves on the tire shoulder improve water drainage and grip on snowy roads. Comparable to the design of the sidewalls of off-road tires with their large, textured grooves, the contact area on ice and snow is increased, and the scooping or traction behavior on snowy roads is improved. A three-dimensional sipe design features deep, medium-depth, and shallow sipes at various points on the block pattern. The center rib has the deepest sipes, providing increased traction on ice and snow, while the sidewall has the shallowest sipes, which increases strength and improves cornering stability.
