TREAD OF A PNEUMATIC TYRE FOR A VEHICLE

The tread has profile elements (2,3) which are separated by grooves (5-7), and radially outer surface which are formed by fine incisions (8) extended along extension direction of line (9). The incisions are formed in wave/zigzag shapes along the main extension direction of line, by forming peaks and...

Zusammenfassung:The tread has profile elements (2,3) which are separated by grooves (5-7), and radially outer surface which are formed by fine incisions (8) extended along extension direction of line (9). The incisions are formed in wave/zigzag shapes along the main extension direction of line, by forming peaks and valleys. The length between neighboring minimum values of rectilinear portion of incision is lesser than length between neighboring mountain peak values of wave/zigzag portion of incision. The amplitude of rectilinear portion is lesser than that of wave/zigzag portion of incision.
