Title:
空気入りラジアルタイヤ
Document Type and Number:
Japanese Patent JP3749296
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To restrain wandering and ensure linear movement stability by laminating a belt layer with at least three belts, dividing the belt of the innermost layer with the equatorial surface of a tire put between, disposing them at an interval, and making the other belt layers own a protruding cross-section in a width direction outside in the radial direction of the tire. SOLUTION: A belt is made to own a protruding cross-section in a width direction outside in the radial direction of the tire in the central part of a tread by disposing a rubber layer 6 at a separated part between a carcass 2 and the first belt 3-1 and includes a tire equatorial surface M. A width center of the rubber layer 6 substantially meet the tire equatorial surface M. The second and third belt plies have stepping-off and owns the protruding cross-section in a width direction outside in the radial direction of the tire because the cross-section of the rubber layer 6 is of roughly rectangle shape. It is thus possible to attain a more wandering restraint effect by disposing a groove 5-1 of the equatorial surface side of the tire at a distance of 16mm from the equatorial surface of the tire.
