Title:
PNEUMATIC TIRE FOR TWO-WHEELER
Document Type and Number:
Japanese Patent JP3934755
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To improve grounding property at the time of revolution and to provide stable revolving force on a pneumatic tire for a two-wheeler.
SOLUTION: It is possible to lower vertical spring constant without lowering lateral rigidity when a side wall 18 is constituted so as to satisfy 0.4≤HS/Ho≤0.7, 0.8≤tu/ts≤1.1 and 0.8≤td/ts≤1.1 at the time of specifying dimension from a standard line BL passing a rim flange upper end part 12A to an intersection of a first curved surface part 18A and a second surved surface part 18B as HS, dimension from the standard line BL to an intersection Te of the first curved surface part 18A and a tread surface A as Ho, a rubber gauge of the side wall 18 at the intersection S as ts, a rubber gauge at the first curved surface part 18A in a range of 0.1-0.2Ho from the intersection S to the outside in the tire radial direction as tu and a rubber gauge at the second curved surface part 18B in a range of 0.1-0.2Ho from the intersection S to the inside in the tire radial direction as td. As a result, the grounding property at the time of revolution is improved and the revolving force is also improved.
