    摘要： The invention relates to a tyre for a private passenger vehicle comprising a tread extended on either side by flanks, that tread being provided with an asymmetrical sculpted design relative to a median plane dividing that tread into two parts with a same axial width, that axial width being measured in a direction parallel to the axis of rotation, an outer part and an inner part, that outer part being situated between that median plane and the flank designed to be placed on the outside of a vehicle and the inner part being situated between the same plane and the flank designed to be placed toward the inside of the same vehicle, the inner part and the outer part each comprising at least one hollow forming a slot or designed to form a slot from a partial wearing-off of the tread, those hollows defining, in new condition and for each part (inner and outer), a total hollow volume, ViO and VeO, respectively, a hollow surface rate, TiO and TeO, respectively, those rates being different from zero and such that in new condition, there is a ratio RO between the hollow volume of the inner part and the hollow volume of the outer part, and in each worn condition (U) chosen between the initial state and the wear limit of the tread, there is a ratio RU between the hollow volume of the inner part and the hollow volume of the outer part, said tyre being characterised in that, at least from 80% wear measured on the tread thickness to be worn off, the ratio RU is greater than the ratio RO.

    摘要： The invention relates to the reinforcing ply of a passenger vehicle tyre. The invention aims to provide good resistance to penetration and perforation of the tyre summit by foreign objects, having a simple and lightweight reinforcing architecture. According to the invention, the hooping layer (71) has a breaking strength per mm of axial width of the hooping layer FR equal to at least 35 daN/mm and has a secant modulus of extension MA equal to at least 250 daN/mm, for an applied force F equal to 15% of the braking strength FR of said hooping layer (71). The working ply (6) comprises a single working layer (61), the working reinforcements of which form an angle A
    T of at least 30° and at most 50° with respect to the circumferential direction (ΥΥ'). The carcass reinforcements of the at least one carcass layer (81) form an angle A
    c2 equal to at least 55° and equal to at most 80° with respect to the circumferential direction (ΥΥ') and in the equatorial plane (XZ), and have an orientation opposite to that of the angle A
    T of the working reinforcements, in such a way that the carcass reinforcements and the working reinforcements constitute a triangulation.
