Winter tyre with triangular shapes - with triangles of any size, apex angle and number

摘要

Winter tyre comprises triangular shapes of any size, apex angle and number, and any shapes derived from the triangles, e.g. pentagons. The tyre with its triangular shapes and sharp profile provides better directional stability and better braking properties. The longitudinal strips between the triangles act only as secondary directional stabilisers and can be omitted. Also, the apex angle of the triangles is not important, but only the shape. The tyre has improved driving properties in both soft snow and ice than conventional winter tyres.
