Title:
【発明の名称】ランフラット用の空気入りタイヤ
Document Type and Number:
Japanese Patent JP3064225
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make a driver recognize air leakage from tire deformation, and improve run flatness by increasing travel distance in a deformed condition at inner pressure of zero without causing weight increase or degradation in rolling resistance, ride comfortableness and the like. SOLUTION: The tire maximum width height Hm from a bead base line BL is set at 0.4 or less of tire cross-section height Ht, and a distance HD between a bead inner surface point where a radial line X raised along a bead outer surface crosses the tire inner surface on bead part side and a tread inner surface point where it crosses the tire inner surface on tread part side is 0.15 time or less of a bead radius Rr which is a distance between the axial center of the tire and the bead base line BL.
