Abstract
A motorcycle tire includes a pair of bead portions each with a bead core therein, the pair of bead portions including a pair of rim contact surfaces that comes into contact with a standard wheel rim under a standard-rim mounted condition. Each rim contact surface includes a bead bottom surface, a bead side surface, and a bead heel surface connecting the bead bottom surface and the bead side surface. Under a virtual-rim mounted condition, in at least one of the pair of bead portions, a diameter of an intersection of a virtual first straight line expanded outwardly in the tire axial direction from the bead bottom surface and a virtual second straight line expanded inwardly in the radial direction from the bead side surface is 99.0% to 99.6% of a rim diameter of the standard wheel rim.
Claims18
A motorcycle tire comprising:
- a pair of bead portions each with a bead core therein, the pair of bead portions comprising a pair of rim contact surfaces that comes into contact with a standard wheel rim under a standard-rim mounted condition in which the tire is mounted onto the standard wheel rim and inflated to a standard pressure,
- wherein
- each rim contact surface comprises
- a bead bottom surface located inwardly in a tire radial direction of the bead core and extending in a tire axial direction,
- a bead side surface located outwardly in the tire axial direction of the bead core and extending in the tire radial direction, and
- a bead heel surface connecting the bead bottom surface and the bead side surface, and
- under a virtual-rim mounted condition in which the tire is not mounted onto a rim but an axial width of the bead side surfaces of the pair of bead portions is held at a rim width of the standard wheel rim, in at least one of the pair of bead portions, a diameter of an intersection of a virtual first straight line that is expanded outwardly in the tire axial direction from the bead bottom surface and a virtual second straight line that is expanded inwardly in the radial direction from the bead side surface is 99.0% to 99.6% of a rim diameter of the standard wheel rim.
