Abstract
A method of mounting dual tires on motor vehicles, in which the tires have lateral grooves in the circumferential direction includes positioning the tires so that the neighboring lateral grooves on the respective tire faces nearest each other have phase differences in the circumferential direction. The phase difference between the neighboring lateral grooves is preferably one half of a pitch and the pitch is preferably smaller than 16 cm, and more preferably smaller than 13 cm.
Claims9
A method of mounting dual tires on a motor vehicle in which said tires have lateral grooves in the circumferential direction of said tires and in which said tires of the dual tires have the same tread pattern,
- said mounting method characterized in that said tires are mutually separated by a predetermined distance along a direction of a wheel shaft on which said tires are mounted, and the neighboring lateral grooves on the respective tires that lie on the inside and the outside of the faces of the dual tires nearest one another, are positioned in the circumferential direction so that said neighboring lateral grooves are shifted with respect to one another by substantially one half of a pitch of the grooves in the circumferential direction.
A method of mounting dual tires on a motor vehicle in which said tires have lateral grooves in the circumferential direction of said tires,
- said mounting method characterized in that said tires are mutually separated by a predetermined distance along a direction of a wheel shaft on which said dual tires are mounted, and the neighboring lateral grooves on respective tires that lie on the inside and the outside of the faces of the dual tires nearest one another, are positioned in circumferential direction so that said neighboring lateral grooves are shifted with respect to each other by substantially one half of a pitch of the grooves in the circumferential direction in order for sound waves generated by the neighboring lateral grooves to have a significant magnitude of phase difference therebetween, wherein said sound waves have the same frequency.
A method of mounting dual tires on a motor vehicle in which said tires have lateral grooves in the circumferential direction of said tires,
- said mounting method characterized in that said tires are mutually separated by such a distance along a direction of a wheel shaft on which said dual tires are mounted such that a distance between the neighboring lateral grooves on each tire satisfies a condition
- S>(PC/8V)
- wherein P is a pitch in circumferential direction of the lateral grooves, C is the velocity of sound and V is 100 Km/h, and the neighboring lateral grooves on the respective tires that lie on the inside and outside of the faces of the dual tires nearest one another are positioned in the circumferential direction so that said neighboring lateral grooves are shifted with respect to one another by substantially one half of a pitch of the grooves in the circumferential direction.
