PROBLEM TO BE SOLVED: To eliminate the delay of handle responsiveness easy to be generated when tires are installed with inward inclination by positioning the center line of a rib in the central circumferential direction with a displacement at a specified value from the tire equatorial plane in the axial direction of the tire. SOLUTION: Tires are installed in an expanded stride shape at a vehicle while inclined inside at 1.5 degree of camber angleθ. A tread is formed with a tread pattern provided with a pair of central circumferential grooves 1, 2 in right and left arranged in both sides of the tire equatorial plane and extended in the tire circumferential direction and central circumferential ribs 3 arranged inside of the pair of central circumferential grooves 1, 2 in right and left and extended in the tire circumferential direction. At this stage, the central circumferential ribs 3 are arranged asymmetry in right tan left so that the center line C of the central circumferential ribs 3 are positioned with a displacement from the tire equatorial plane E by a distance (d) in the tire axial direction, and the tire is installed so that a side thereof provided with the eccentrically positioned central circumferential rib 3 is arranged inside of the vehicle. A distance D is computed with R.tanθ. |
