Specially designed 3D Micro-Gauge Siping improves handling by allowing the tread element blocks to interlock together. This reduces tread squirm and improves tread element stability, which increases handling. 3D sipes maintain increased traction and handling throughout the entire life of the tyre.

NEW 3D Micro-Gauge Siping Exclusive to the Discoverer HT3

Traditional Sipes are allowed to move more freely with less stability.

Between each individual 3D Sipe, the interlocking nodes can be seen.

Each Tread block has 2 zig-zag, full depth 3D Sipes

3D Micro Gauge Siping

3D Sipes interlock together as the tyre is in motion for stability and increased handling.

The diagram below shows the cross section of an individual sipe performing under the weight of a vehicle. In the stationary position (1) both sipes are stable, as the tyre moves along the road surface (2,3) you can see the difference in stability between the traditional siping and the 3D Siping.
