摘要： Provided is a pneumatic tire for motorcycles which can exhibit a performance of a new tire at an early period and enables visual confirmation that the tire as new is worn to such an extent as to be capable of sufficiently exhibiting its performance. The pneumatic tire for motorcycles includes a tread portion 10 formed into a ring shape, in which the tread portion 10 is provided with a width direction shallow groove 11b in which the shallow groove having a width of 0.1 to 2.0 mm and a depth of 0.1 to 2.0 mm is designed to extend at least in a tire width direction. A length of the width direction shallow groove 11b is greater than or equal to 50% of a width of a tire ground contact surface, and the width direction shallow groove 11b is provided at intervals which are shorter than a length of the tire ground contact surface.

摘要： A pneumatic tire includes a tread having a center main groove and a pair of shoulder main grooves. A pair of middle land sections in the tread is positioned between the shoulder and center grooves. Each of the shoulder and center grooves has a groove width set in range of 7 to 9% of width of the tread footprint. An outer middle land portion is divided into first and second middle land portions by a middle narrow groove. The first land portion forms rib. The second land portion has outer middle lateral grooves connected to the center groove and the narrow groove. Each lateral groove includes first portion, second portion having the opposite inclination to the first portion and connection portion between the first and second portions. The connection portion is positioned on the center groove side from the center of the outer land portion in the axial direction.

摘要： In a tread part (1), a tilted land portion (200) is divided into multiple blocks by a tilted narrow groove (300) and branched narrow grooves (350). Tilted main grooves (100) include an upper tilted main groove (101) and a lower tilted main groove (102). The branched narrow grooves (350) include first branched narrow grooves (350a) and second branched narrow grooves (350b). First blocks (210) and second blocks (220) have quadrilateral or pentagonal shapes. Of the first blocks (210), one first block and another first block adjacent to the one first block in a tilt direction KC have the same shape. Of the second blocks (220), one second block and another second block adjacent to the one second block in the tilt direction KC have the same shape.

摘要： A tyre having a tread is described. The tyre has a central portion located across an equatorial plane, a first shoulder portion located towards an outer side of the tyre and a second shoulder portion located towards an inner side of the tyre. The central portion is separated from the first shoulder portion by two first circumferential grooves. The first shoulder portion and the second shoulder portion have a plurality of first transverse grooves having a first end located substantially at the respective edge of the tread, having a width greater than or equal to about 4 mm and an axial extension equal to at least 50% of the width of the shoulder portion in which they are located.
