Abstract
A pneumatic tyre has a tread band for engaging a road surface at a footprint area of the tyre, shoulder blocks arranged along shoulder circumferential ribs, and central blocks arranged along central circumferential ribs. Four circumferential grooves separate the shoulder ribs and central ribs from each other. The central blocks are separated along their entire axial width by transversal sipes, the transversal sipes defining two endpoints at their respective axially outer ends where they intersect the circumferential grooves.
Claims18
A pneumatic tyre with a tread band for engaging a road surface at a footprint area of the tyre, the tread band comprising:
- two shoulder areas at the axially outer ends of the tread band;
- a central area identified between the shoulder areas;
- a row of shoulder elements arranged along first circumferential ribs in each of the shoulder areas;
- at least two rows of central elements arranged along second circumferential ribs in the central area;
- and
- at least three circumferential grooves separating the first and second circumferential ribs from another circumferential rib, wherein the central elements are separated along their entire axial width by transversal sipes, the transversal sipes defining two endpoints at their respective axially outer ends where they intersect the circumferential grooves.
The tyre of claim wherein the extension along the axial direction between the two endpoints of the transversal sipes is substantially S-shaped.
