PNEUMATIC TYRE (VERSIONS)

摘要

FIELD: tyre industry; truck tyres. ^ SUBSTANCE: proposed pneumatic tyre has flange, two side strips and two beads, skeleton with first reinforcement members arranged in line in circular direction at least in one circular row at least from one of said beads to one of said side strips, secured on said bead and flange. Said bead has zone of fastening for holding skeleton containing at least one second reinforcement member with circular direction engaging with adjacent section of skeleton through fastening rubber mix in contact with second reinforcement member and with adjacent sections of first reinforcement members. Fastening rubber mix at 10% deformation has modulus of elasticity from 10 to 20 MPa. Said rubber mix contains at least one synthetic elastomer pf BSR group and polybutadienes with total content of synthetic elastomer exceeding 50% of totals weight of elastomers. ^ EFFECT: facilitated mounting and demounting of pneumatic tyres. ^ 9 cl, 4 dwg
