发明名称 TIRE FOR MOTORBIKE
摘要 The present invention improves turning performance and dry grip performance with good balance. In a ti re for a motorbike, a tread part (2) is provided with a first inclined groove (11) and a second inclined groove (12) disposed closer to a tread end (2t) than is the first inclined groove (11). The first inclined groove (11) is provided to a forward-movement grounded area (ES). An inner end (12i) of the second inclined groove (12) is provided in an area within a range 2% of a tread expansion radius (CW) centered about an end edge (Se) of the forward-movement grounded area (ES). An outer end (12e) of the second inclined groove (12) is provided to a position displaced from the inner end (12i) of the second inclined groove (12) toward the tread end (2t) by an interval 20%-30% of the tread expansion radi us (CW). Either no other grooves besides the second inclined groove (12) are provided to a second inclined groove formation area (E2), or the length of the area i n the direction of expansi on wi dth where another groove is located in the second inclined groove formation area (E2) is 25% or less of the expansion width of the second inclined groove formation area (E2).
