Abstract
A pneumatic tire comprises a tread-sidewall reinforcement extending between the tire sidewall portions through the tread portion which has a symmetrical cord arrangement to prevent ply steer. The tread-sidewall reinforcement is made of a series of loops of at least one reinforcing cord which loops spread over the circumference of the tire. The tread-sidewall reinforcement can be formed as a carcass or a reinforcing layer disposed outside a carcass. When viewed in the radial direction, the inclination angle of the reinforcing cord with respect to the tire circumferential direction is substantially 90 degrees at the tire equator and decreases to substantially 0 degree gradually from the tire equator towards the bead portions. When viewed in the axial direction, the inclination angle of the reinforcing cord with respect to the radial direction is in the range of from 60 to 90 degrees.
