摘要： The invention provides a base tire manufacturing method and a base tire having a proper thickness for the rubber layer by setting the thickness of the rubber layer in such a manner as to optimize the buffing allowance for the cure-molded base tire without placing limits on the shape of the post-buffing base tire. The base tire thus manufactured has a belt layer, an outermost rubber layer of a predetermined width disposed over the belt layer for application of a tread therto, and edge rubber members at both axial ends of the outermost rubber layer. For this base tire, the loss tangent (tan ´) of the outermost rubber layer is set lower than the loss tangent (tan ´) of the edge rubber members, the pre-buffing thickness A1 at the equator of the outermost rubber layer is set at "post-buffing thickness A2 X 150%" or less, and the post-buffing thickness A2 is set in a range of 1 mm to 3.5 mm.

摘要： A tire exhibiting a desired design performance can be manufactured at a low cost using a precured tread having a mounting surface formed flat. In the process of manufacture, a base tire formed with a tread mounting surface having curvatures in the axial and circumferential directions of the tire and a precured tread having a mounting surface formed flat, which is to be applied to the tread mounting surface of the base tire, are used. The precured tread has grooves (9) in its tread pattern surface opposite from its mounting surface. And the circumferential and axial lengths of the grooves (9) are formed shorter than desired design values, based on the differences in the circumferential and axial lengths between when the mounting surface of the tread applied to the base tire is curved along the curvatures of the tread mounting surface of the base tire and when the mounting surface of the tread is in a flat state.

摘要： A tire having aggressive tread features with improvements in uniformity that can also improve endurance is provided along with a method and apparatus for manufacturing such a tire. The tire and its manner of manufacture can achieve a reduction or elimination of certain non-uniformities that can occur during the molding of large tread blocks. The reduction or removal of these non-uniformities can improve temperature performance to provide increased tire endurance.

摘要： The invention include methods and apparatus for demolding a tread. The methods include arranging one or more rollers to extend across a transverse extent of a tread molding cavity and across an outer, exposed side of a tread. The one or more rollers are freely-rotatable and arranged to define a demolding path of the tread extending from the mold. The tread is demolded from the tread molding cavity along the demolding path such that the tread is initially directed outwardly from a molded position within the tread molding cavity at an initial angle less than 90 degrees from the molded position, the tread continuing along the demolding path until the tread is directed away from the molding cavity in a direction 90 degrees from the molded position at a perpendicular position located a distance from the molding cavity at least equal to approximately 80% of the tread thickness.
