Title:
MANUFACTURE OF SOLID TIRE
Document Type and Number:
Japanese Patent JPH09141760
Kind Code:
A
Abstract:

To improve durability while shortening the vulcanizing time.

A core tire 6 with a tread buff face 7 is formed by eliminating the rubber of a used solid tire tread face and buffing the tread face. Further, a tread rubber 10 for forming the tread face is integrally junctioned to the read buff face 7 by vulcanization to manufacture a solid tire. In addition, a height TB in the radial direction between the center part position in the tire axial direction of the tread buff face 7 and the outer edge of the bead bottom of the tire after vulcanization is set to at least, 75% and 95% or less of the height TH in the radial direction between the maximum diametral position of the tread face of the tire after vulcanization and the outer edge E of the bead bottom. Besides, the height TC in the radial direction between the outer end position in the tire axial direction of the tread buff face 7 and the outer edge E of the bead bottom is set to at least, 60% and 70% or less. Thus the cross section shape including the tire axis of the tread buff face 7 is recessed facing outwardly in the radial direction.
