text: According to the invention a pneumatic tire for vehicle wheels is provided which has a radial carcass made up of at least one layer of cords lying in planes substantially radial, a tread and a breaker arranged between the carcass and the tread and comprising at least two superimposed cord layers, the cords being inclined at an angle between 10° and 35° with respect to the equatorial plane of the tire and being parallel to one another in any layer and crossing those of the adjacent layer, the breaker comprising, moreover, in a radially outer position with respect to the two layers, at least one strip of cords of textile material which shrinks in length when subjected to the action of heat, the cords being arranged in parallel position to the equatorial plane of the tire, characterized by the fact that it further comprises in each tire sidewall, a reinforcement constituted of at least a cord layer arranged in an axially outer position to the carcass, the radially innermost edge of the reinforcing layer being substantially in correspondence with the bead core of the relative sidewall and axially external of the turned up portion of the carcass which is wound around the bead core, a radially outer stretch of the reinforcing layer being disposed in the breaker between the two super-imposed cord layers and the strip which has the cords arranged in a parallel position to the equatorial plane of the tire, each cord of the reinforcing layer being inclined with respect to the circumferential lines of the tire at an angle which decreases along the path of the cord from the radially innermost edge toward the stretch and variable in a range whose extreme values are 55° and 15°.
