Abstract: A tire is configured having first and second shoulder rows of shoulder tread elements opposite respective first and second interior rows of interior tread elements, separated respectively by circumferentially extending, zig-zag shaped first and second grooves within a tire tread region. Each groove is defined by opposed shoulder tread elements and interior tread elements and includes a circumferentially continuous see-through central groove portion extending parallel to a circumferential centerplane of the tread. The see-through circumferential grooves communicate with angular intermediate and shoulder lateral grooves having a relatively wide mouth dimension adjacent to a respective circumferential grooves. Staggered in and out shoulder regions within the shoulder tread elements facilitate gripping edges and prevent mud clogging of the shoulder grooves.

Abstract: A pneumatic tire includes a circumferential tread disposed between opposing tread edges and opposing sidewalls disposed radially inward from the opposing tread edges. Each sidewall has a rectangular extension block and a triangular extension block. The rectangular extension block protrudes axially outward by a first amount. The triangular extension block protrudes axially outward by a second amount. The first amount is less than the second amount.

Abstract: The tread of a pneumatic tire has a plurality of tread elements separated by at least one groove, the tread elements having a depth as determined from an initial tread surface and the base of the at least one groove. The tread has at least one chamfer. The chamfer is divided into at least two inclined adjacent portions with the inclined adjacent portions being inclined at different inclination angles relative to the tread surface. The difference in inclination angles of the different portions is at least 100. The inclined adjacent portions are both connected to an inclined common area, the inclined common area being adjacent to the initial tread surface.

Abstract: A tire has a tread and a pair of opposing shoulders. In the first sidewall, a series of extension blocks creates a pair of concentric rings. In the second sidewall, a different configuration of extension blocks may be present. The second sidewall has alternating extension blocks where one of the blocks has a portion that is located radially inward of the other block.
