Abstract: Embodiments are directed to a pneumatic off-road tire having an inner shoulder, an outer shoulder and a tread therebetween. The tread has a central axis and includes a plurality of generally curved first grooves. Each first groove has a first end disposed near the outer shoulder and a second end 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, each connecting the second end of a first groove to a first end of another first groove, are included. The first and second grooves define a cascading repetition of tread blocks. Chamfers are defined on certain corners of the tread blocks that are adjacent to the first grooves and that expose a tread block wall following the chamfer, relative to a rotation of the tire, to an off-road contact surface.

Abstract: Pneumatic tire including a sealant material composition providing puncture sealing property within the sealant material composition includes a compound containing a diphenyldisulfide structure therein.

Abstract: 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.
