FORDONSDECK MED RADIALSTOMME FOR TUNGA LASTBILAR

摘要

A radial pneumatic tyre for heavy vehicles comprises a radial carcass reinforcement 2 and a crown reinforcement which is formed of at least two plies 24,25 of cords and which is parallel to the carcass reinforcement along a mid- circumferential zone less wide than the crown reinforcement. The neutral fibre of each side wall of the carcass reinforcement at least radially outwardly from points 22 follows a natural equilibrium profile the continuation 2' of which is located below the crown reinforcement in the radial direction. This profile passes through a point 21 at which tangent T is parallel to the rotational axis YY' of the tyre and which point is spaced from the mid-circumferential plane by a distance d greater than the axial half width I of the zone of parallelism between the reinforcement and the carcass.
