OFF-ROAD TIRE TREAD HAVING STRAKE AND CHAMFER STRUCTURE

摘要

A pneumatic tire (10) has an inner shoulder (11), an outer shoulder (12) and a tread (13) therebetween. The tread has a central axis (A) and includes a plurality of first grooves (14). Each first groove has a first end (15) disposed near the outer shoulder and a second end (17) disposed near the inner shoulder so that each first groove crosses the central axis. The first end is spaced circumferentially from the second end. A plurality of second grooves (16) is provided with each second groove connecting the second end of a first groove to a first end of another first groove. The first and second grooves define a cascading repetition of tread blocks (18). Chamfers (20) are defined on certain corners of the tread blocks that are adjacent to the first grooves.
