Title:
PNEUMATIC TIRE
Document Type and Number:
Japanese Patent JPS6271707
Kind Code:
A
Abstract:
PURPOSE:To improve the steering stability and drive feeling and reduce noise by setting the relation between the longitudinal and the lateral rigity of the outside part of a tire positioned outside a vehicle and the relation between the longitudinal and lateral rigidity of the inside part of the tire inside the vehicle so as to satisfy the following equations. CONSTITUTION:The longitudinal rigidity KVO and the lateral rigidity KLO of the tire outside part positioned outside a vehicle and the longitudinal rigidity KVI and the lateral rigidity KLI of the tire inside part positioned inside the vehicle are set so as to satisfy the following equations. With such constitution, the drive feeling can be improved by reducing the deflection quantity of the tire, and the steering stability can be improved by improving the cornering force and the cornering power. Further, noise can be reduced by reducing the vibration in the vertical direction.
