Protective barrier for tire sidewall

A pneumatic tire, comprising:

• a substantially toroidal two-ply carcass cord layer comprising a second ply overlying a first ply,
• a tread portion surrounding a circumferential portion of said carcass cord layer and having a left side and a right side, said tread portion including at least one reinforcement belt;
• a left sidewall portion surrounding a left side of said carcass cord layer and extending from said left side of said tread portion;
• a right sidewall portion surrounding a right side of said carcass cord layer and extending from said right side of said tread portion;
• left and right bead portions extending, respectively, from said left and right sidewall portions, each of said bead portions including a reinforcing bead, said first and second carcass cord layer plies being wrapped around said reinforcing beads to forms respectively, first ply turn-up portions and second ply turn-up portions, respective ends of said first ply turn-up portions being spaced from ends of said second ply turn-up portions, said first turn-up portions extending further from said reinforcing beads than said Second turn-up portions;
• and
• substantially flexible protective barriers comprised of a composite aramid and nylon material disposed (i) intermediate said left side of said carcass cord layer and said left sidewall portion and (ii) intermediate said right side of said carcass cord layer and said right sidewall portion, said protective barriers each having a first end and a second end, said first ends of said protective barriers each being spaced from said reinforcement belt so as not to be overlapped by said reinforcement belt, said second ends of said protective barriers being located between said respective ends of said first ply turn-up portions and said second ply turn-up portions and at least partially overlying sides of said first ply turn-up portions which face said carcass cord layer.
