It relates to tire with axial width exceeding 37 inches. According to invention, tire has working reinforcement crown consisting of at least two uninterrupted working layers and terminating from each side of circumferential (equatorial) middle plane in at least two half-layers whose metal reinforcement members form angles exceeding minimum angle which is formed by reinforcement members of uninterrupted layers relative to circumferential direction. Half-layer passing in axial direction outwards further than other half-layers is in contact with widest in axial direction uninterrupted layer in crown, and two half-layers cover in radial direction axially outer end of said working layer widest in axial direction. ^ EFFECT: increased service life of tire. ^ 8 cl, 4 dwg |
