Abstract
1372638 Pneumatic tyres MICHELIN & CIE COMPAGNIE GENERALE des ETABS MICHELIN 17 May 1972 [18 May 1971] 23271/72 Heading B7 A tyre comprising two plies 11, 12 of cords arranged in radial or substantially radial planes, includes a crown reinforcement 5a stiffer at its edge regions than at its central region, and a respective insert 13, 14 in each side wall. The inserts are formed of an elastomer having a modulus of elasticity at 100% elongation greater than 200 g/mm<SP>2</SP>. The radial height h of the inserts is such that 2/3H#h#¢H, and the maximum thickness of the inserts is from 2%-5% of H, H being the radial height of the tyre measured between the bead seats and the radially outermost part of the tread. The crown reinforcement 5a is constituted by a ply of cords 6 whose edges 7 and 8 have been folded over so as to enclose the edges of ply of cords 9. Ply 6 is comprised by resilient metal cords making an angle of 22 degrees with one side of the mid circumferential plane, and ply 9 is comprised by non-resilient metal cords making an angle of 34 degrees with the other side of the mid circumferential plane, and plies 11 and 12 are made of rayon cords. The Specification discloses cord constructions for the plies 6 and 9.
