Pneumatic tire

摘要

The present invention is directed to a pneumatic tire comprising a tread (110), a belt structure (112), and a carcass (114), wherein the carcass (114) comprises a preferably radial ply (118) and two bead sections (130a, 130b), each bead section (130a, 130b) comprising a bead (132) and an apex comprising an inner apex section (138) and an outer apex section (136), wherein the inner apex section (138) comprises a rubber composition having a shear storage modulus G' as measured at 1% strain and 100°C according to ASTM D5289 ranging from 18 to 32 MPa, and wherein the outer apex section (136) comprises a rubber composition having a shear storage modulus G' as measured at 1% strain and 100°C according to ASTM D5289 ranging from 1.2 to 10 MPa.
