    摘要： This invention relates generally to tires having treads that have a configuration and/or properties for maintaining hydroplaning performance, dry braking performance and improved wear resistance, and, more specifically, to a tire that has a tread that N has a variable sipe density, i.e a higher sipe density in its central portion and a lower sipe density in its shoulder portions, as well as a round crown with a predetermined inflated profile droop. Another embodiment of the present invention further includes the addition of a member that provides more structural stiffness across the crown of a tire, such that better compromises between hydroplaning, dry braking, and wear performances can be obtained.

    摘要： Rubber compositions and articles made such rubber compositions having at least 80 phr of a styrene-butadiene elastomer modified with a functional group that is capable of interacting with a silica reinforcing filler and having a glass transition temperature of between −60° C. and less than −40° C. The rubber compositions may also include an effective amount of a plasticizing system having a plasticizing resin and a plasticizing liquid, wherein the effective amount of the plasticizing system provides the rubber composition with a shear modulus G* measured at 60° C. of between 0.9 MPa and 1.5 MPa and a Tg of between −35° C. and −15°. The filler for the rubber compositions is silica and there is further a curing system.

    摘要： A motor vehicle fitted with a system for controlling the camber (&thgr;) of the wheels of the vehicle on a bend, including, for each wheel of at least one front axle and/or rear axle of the vehicle, a suspension having a pair of suspension upper and lower arms, articulated at their outboard ends to a hub carrier and attached at their inboard ends to the body of the vehicle. The lower and upper arms of each pair are articulated at their respective inboard ends to a pivot transfer lever which is, in turn, mounted on the body by an articulation, the axis of rotation of which is contained in a longitudinal and vertical plane of the vehicle, the pivot transfer lever being capable of pivoting in such a way as to incline the wheels on the appropriate side.

    摘要： A tire tread formed at least in part from a rubber composition that is based upon a cross-linkable rubber composition that may include between 50 phr and 90 phr of a first highly unsaturated elastomer being middle chain functionalized with an aminoalkoxysilane group and having a Tg of between −108° C. and −45° C. and between 10 phr and 50 phr of a second highly unsaturated elastomer being end-chain functionalized with a silanol group and having a Tg of between −108° C. and −10° C. The rubber composition may further include between 50 phr and 150 phr of a silica filler and a plasticizing system comprising between 5 phr and 120 phr of a plasticizing resin having a Tg of at least 25° C. and between 0 phr and 60 phr of a plasticizing liquid.
