Abstract: A pneumatic tire includes a plurality of protrusions on a bottom of each of the grooves. The height of the protrusion is variable in a profile of the protrusion in a circumference direction of the pneumatic.

Abstract: In a pneumatic tire, a block unit includes a center block and side blocks separated by a communication groove. Aspect ratios of the center block and the side blocks are approximately the same. The center block and the side blocks are arranged such that a longitudinal direction of a rectangle relating to the aspect ratio of the center block and longitudinal directions of rectangles relating to the aspect ratios of the side blocks are approximately orthogonal to each other. Size ratios of a short side of the rectangle relating to the aspect ratio of the center block and the long sides of the rectangles relating to the aspect ratios of the side blocks are in a range equal to or more than 0.90 to equal to or less than 1.10.

Abstract: A pneumatic tire, in which a concave portion adjacent to a convex mark is provided on a surface of a sidewall portion, and a ratio of a volume v of the concave portion to a volume V of the convex mark is set as: 0.8V≦v≦1.2V, alternatively, a convex portion adjacent to a concave mark is provided on the surface of the sidewall portion, and a ratio of a volume w of the convex portion to a volume W of the concave mark is set as: 0.8W≦w≦1.2W, thus suppressing a bend of a carcass layer located under a mark spot of the sidewall portion, and making it possible to maintain a carcass line approximately uniformly on a circumference thereof.

Abstract: A tread area is divided into a plurality of lands by a plurality of grooves formed in the tread area. Each of the grooves includes a plurality of protrusions arranged at intervals on a bottom of the groove. The protrusions are lower than the lands from the bottom of the groove, and separated from the lands. Each of the protrusions includes a protrusion main body having a top portion that is a highest portion from the bottom of the groove, and a slope portion having a slop that makes an angle with the bottom of the groove in a range between 3 degrees and 60 degrees. The slope portion is formed in at least one direction along the groove.

Abstract: To provide a pneumatic tire capable of improving resistance to stone drilling while ensuring snow traction performance, protrusions are arranged at intervals in a groove, each of the protrusions being lower than a height of a block and being separated from the block. The protrusion includes a protrusion main portion having a top portion, and a sloped portion having a slope of which angle with a groove bottom is formed in a range from 3 to 60°. The sloped portion is formed at positions in two directions which are mutually opposite to each other at least along the groove. Consequently, a stone trapped within the groove moves up to the top portion along the slope, and is ejected from the groove. Since the protrusions are arranged separately from the block and are arranged at intervals, the capacity of the groove is ensured. Thus, the resistance to stone drilling can be improved while the snow traction performance is ensured.

Abstract translation: 为了提供一种能够在确保积雪性能的同时提高对石材钻孔的抵抗力的充气轮胎，突起间隔设置在槽中，每个突起比块的高度低，并与块分离。 所述突起包括具有顶部的突起主体部分和具有与槽底角度形成在3°至60°的范围内的倾斜部分的倾斜部分。 倾斜部分形成在至少沿凹槽彼此相互相对的两个方向上的位置处。 因此，被捕获在凹槽内的石块沿斜坡向上移动到顶部，并从凹槽中排出。 由于突起与块分开布置并且间隔地布置，因此确保了槽的容量。 因此，可以在确保雪地牵引性能的同时提高对石材钻孔的抵抗力。
