Abstract:
A tire for a motorbike can improve turning performance and dry grip performance with good balance. In a tire for a motorbike, a tread part is provided with a first inclined groove and a second inclined groove disposed closer to a tread end than is the first inclined groove. The first inclined groove is provided to a forward-movement grounded area. An inner end of the second inclined groove is provided in an area within a range 2% of a tread expansion radius centered about an end edge of the forward-movement grounded area. An outer end of the second inclined groove is provided to a position displaced from the inner end of the second inclined groove toward the tread end by an interval 20%-30% of the tread expansion radius. Either no other grooves besides the second inclined groove are provided to a second inclined groove formation area, or the length of the area in the direction of expansion width where another groove is located in the second inclined groove formation area is 25% or less of the expansion width of the second inclined groove formation area.
