摘要： Tire (1) crown reinforcement (3) comprises: protective reinforcement (5) comprising layer (51, 52) comprising reinforcers forming, with the circumferential direction, an angle at least equal to 10°; working reinforcement (6) comprising two layers (61, 62) respectively having axial width (L61, L62) and comprising reinforcers, crossed from one working layer to the next and forming, with the circumferential direction, an angle at most equal to 60°; and additional reinforcement (7), centred axially on an equatorial plane of the tire, comprising layer (71, 72) having axial width (L71, L72) at most equal to 0.9 times the shortest of the axial widths (L61, L62) and comprising reinforcers forming, with the circumferential direction, an angle at most equal to 25°. Additional layer (71, 72) comprises axial discontinuity (81, 82), centred axially on the equatorial plane of the tire, and its width (D1, D2) is at least equal to 0.1 times axial width (L71, L72).

摘要： Tire comprising a crown reinforcement radially inside the tread, and a carcass reinforcement radially inside the crown reinforcement. The crown reinforcement comprises radially from the outside towards the inside: a protective reinforcement comprising two protective layers comprising elastic metal reinforcers which are parallel to one another within each layer and crossed from one layer to the next, forming respective angles A1 and A2 with the circumferential direction, a working reinforcement comprising two working layers comprising inelastic metal reinforcers, parallel to one another within each layer and crossed from one layer to the next, forming respective angles B1 and B2 with the circumferential direction. Angle B1 is non-zero and at most equal to 35° and angle B2 is at least equal to 70° and strictly less than 90°.

摘要： A tire for an agricultural vehicle, having a tread consisting of blocks in pairs separated by voids and arranged, over the width of the tread, in a median row, two intermediate rows and two lateral rows. To obtain compromise between rolling resistance and service life in terms of wear in road use, two consecutive blocks of the median row) are separated by a transverse void with a width (E1) at most 2.5 mm, the mean circumferential slenderness ratio of every block) of the median row is at least 0.95 and at most 1.15, every block of each intermediate row has a leading face) in the circumferential rolling direction tire which forms a mean angle (D2) equal at least to 30° with a radial direction (ZZ′) tire, and the mean circumferential slenderness ratio of every block in each lateral row is at most 0.9.
