Abstract: An apparatus for shock cooling a vulcanized tire includes a vulcanized-tire holding mechanism for holding a vulcanized tire and a tank for holding fluid to shock cool the vulcanized tire. The vulcanized tire is submerged in the fluid for between 4 and 60 minutes whereby the vulcanized tire reaches a predetermined temperature.

Abstract: A pneumatic radial tire has at least one carcass reinforcing ply and a pair of opposing bead portions. Each bead portion has a bead core and a bead apex, while the carcass reinforcing ply has a main portion and two turnups, with one turnup extending from each end of the main portion and having a terminal end. In each bead portion, there is a minimum distance DMIN between the carcass main portion and the carcass turnup, as measured perpendicular to the tire equatorial plane EP. The distance DMIN is not less than 50% of the maximum bead core width WB as measured perpendicular to the equatorial plane EP. In each bead portion, radially outward of the minimum distance DMIN, a radially outermost portion of the carcass turnup extends at an angle so the radially outermost portion of the carcass turnup is divergent from the carcass main portion.

Abstract: A pneumatic radial tire, the tire comprising at least one carcass reinforcing ply and a pair of opposing bead portions. Each bead portion has a bead core and a bead apex, and the at least one carcass reinforcing ply has a down portion located axially inward of the bead and a turnup end located axially outward of the bead core. The turnup end of the ply is about parallel to the down portion.
