A method for determining a sidewall toughness index for a tire includes providing a first tire that includes a pair of sidewalls. A first physical test is conducted on a selected one of the sidewalls of the first tire, and a result of the first test is recorded. A second tire of the same type as the first tire is provided, and includes a pair of sidewalls. A second physical test is conducted on a selected one of the sidewalls of the second tire, and a result of the second test is recorded. The result of each of the first physical test and the second physical test is normalized. A sidewall toughness index is generated by combining the normalized result of the first physical test and the normalized result of the second physical test.

Shoulder for a tire

Tire

A carcass for a pneumatic tire includes a first annular bead, a second annular bead, a first continuous radial ply, a second continuous radial ply, and a third non-continuous radial ply. The first radial ply has two shoulder portions and two lateral edge portions. One lateral edge portion of the first ply extends from one shoulder portion of the first ply radially inward to a location proximal to the first annular bead. The other lateral edge portion of the first ply extends from the other shoulder portion of the first ply radially inward to a location proximal to the second annular bead. The second continuous radial ply has two shoulder portions and two lateral edge portions. One lateral edge portion of the second ply extends from one shoulder portion of the second ply radially inward to a location proximal to the first annular bead. The other lateral edge portion of the second ply extends from the other shoulder portion of the second ply radially inward to a location proximal to the second annular bead. The third non-continuous radial ply has a first portion and a second portion separate and distinct from the first portion. The first portion of the third ply extends from a location proximal to one shoulder portion of the second ply to a location proximal to the first annular bead. The second portion extends from the other shoulder portion of the second ply to a location proximal to the second annular bead.

A segmented moldfor molding a tireis described which has a central axis; plurality of radially movable tread forming segments; two sidewall forming plates, a top sidewall forming plate, and a bottom sidewall forming plate; a top locking ringhaving a plurality of circumferentially spaced openingsfor locking the segments, each opening for lockingproviding a predetermined angular pathfor radially contracting the segmentsupon closing the moldin a locked position. The segmentedmold for molding a tirefurther has a bottom locking ringhaving a complementary plurality of circumferentially spaced openingsfor locking the segments, each opening for lockingproviding a predetermined angular path for radially contracting the segmentsupon closing the mold.
