摘要： Disclosed are a pneumatic tire which enables improvement of durability when air column resonance sound is reduced by adding a member to a bead portion to change a sectional shape of a closed space in a tire circumferential direction, and a pneumatic tire manufacturing method which enables improvement of productivity. In the pneumatic tire in which a carcass layer is arranged between a pair of left and right bead portions and an inner liner layer is provided on an inner side of the carcass layer, volume adjusting members are intermittently arranged between the carcass layer and the inner layer in the bead portions in a tire circumferential direction so as to change a sectional shape of a closed space formed between the tire and a wheel in the tire circumferential direction.

摘要： A monoply pneumatic tire has a reinforced sidewall wherein the reinforcement comprises an extra long turn-up which extends into the belt area of the tire. The tire also has a robust chapex in the bead area of the sidewall which has a shape that results from wrapping the turn-up of the carcass ply around the bead of the tire without an apex. The chapex conforms to the shape of the bead. The material in the chapex corresponds in volume substantially to the combined volume of the apex and the chafer of a similarly sized tire.

摘要： A pneumatic tire comprises a bead core and a rubber bead apex provided in each bead portion, and a carcass comprising a carcass ply turned up around the bead core from the inside to the outside of the tire to form a pair of turned up portions and a main portion therebetween. The bead apex is made of hard rubber disposed between the main portion and turned up portion and extending radially outwards from the bead core. The length (LA) of the bead apex is in a range of from 0.1 to 0.25 times the tire section height (H). A reinforcing cord layer is disposed along the axially inside of the turned up portion. The radially outer end (FU) of the reinforcing cord layer is positioned radially outside the radially outer end (BU) of the bead apex but radially inside the maximum tire section width point (M). The radially inner end (FD) of the reinforcing cord layer is positioned radially outside the radially outer end of the bead core but radially inside the radially outer end (BU) of the bead apex. The length (LB) of the reinforcing cord layer is in a range of from 1.2 to 2.0 times the bead apex length LA. The sidewall portion of the tire has a minimum thickness (Wmin) being in a range of not more than 0.5 times a maximum thickness (Wmax) of a region where the reinforcing cord layer exists.
