Abstract: A work vehicle includes a frame and a row unit that is attached to the frame. The row unit includes a gauge wheel and a ground engaging implement. The gauge wheel is configured to ride on the ground surface and maintain the ground engaging implement at a predetermined vertical position with respect to the ground surface. Furthermore, the work vehicle includes a ground support unit that supports the frame for movement across the ground surface. The ground support unit includes an outer face. The outer face includes a non-treaded side area that defines a lateral side of the outer face. The outer face includes a tread area that is spaced laterally from the lateral edge. The tread area includes a plurality of projections. The non-treaded side area is aligned along the travel direction with respect to the gauge wheel.

Abstract: A pneumatic tire includes a shoulder block in which first shoulder blocks and second shoulder blocks are alternately aligned. Each first shoulder block has a first edge that is on the outer side in a tire axial direction of a tread surface of the first shoulder block. Each second shoulder block has a second edge that is positioned on the outer side in the tire axial direction of a tread surface of the second shoulder block and more toward the inner side in the tire axial direction than the first edge.

Abstract: A pneumatic tire provided with a plural of non-linear ridges 11 in a side wall region, wherein ridges 11 are composed of two or more non-linear ridge groups with different shapes and at least one ridge extends from a rim line R to H 80 which is a position corresponding to 0.8 H when tire height from a rim line to a tire maximum outside diameter is defined as H.

Abstract: The pneumatic tire 1 is provided with a land part 4 in a sidewall region S of a tire and a plurality of marks 11 protruding from a side wall surface, wherein at least one of the marks 11 partially overlaps with the land part 4 and an area of a portion 12 where a mark is overlapped is not greater than 40% with respect to the total area of a mark. In addition, the number of the marks 11 partially overlapping with the land part 4 is not greater than 60 % with respect to the total number of marks. Further, protruded height of the mark 11 from the side wall surface 21 is not greater than 3 mm.
