摘要： An asymmetrical tire is provided that includes at least a crown, a first shoulder having a first tread, and a second shoulder having a second tread. In one embodiment of the present invention, the crown and second shoulder include high-performance tread and the first shoulder includes off-road tread. By using off-road tread on the outer shoulder, the tire will have the visual aesthetics of an off-road tire. And by using high-performance tread on the crown and second shoulder, the vehicle will exhibit a smooth and quiet ride that is fuel efficient, and will not rub on, or interfere with the vehicle's wheel well or splash guard. In one embodiment, an upper portion of the first shoulder includes high-performance tread and a side portion includes off-road tread. By using two different types of tread on the outer shoulder, the tire can provide a smoother ride, while still exhibiting an off-road appearance.

摘要： In a tire with a tread that includes tread pattern elements, a circumferential reinforcement, and first and second circumferential grooves, the circumferential reinforcement is formed of a rubber mixture having a stiffness greater than a stiffness of a rubber mixture forming a remainder of the tread. The tire has an outer side on one side of a median plane of the tire, and an inner side on an opposite side of the median plane. The first circumferential groove is disposed axially toward the outer side relative to the second circumferential groove. The circumferential reinforcement includes a reinforcing element having a tapered shape positioned in each of a group of the tread pattern elements disposed axially toward the outer side relative to one of the first and second circumferential grooves, with the reinforcing elements being axially close to an outer-side face of that circumferential groove.

摘要： A method for controlling the symmetry of the footprint area of a tyre running on a straight trajectory with camber angle different from zero, includes the steps: reducing the contact pressure of the tyre on the footprint area at an inner shoulder (in case of negative camber) or at an outer shoulder (in case of positive camber); and disposing any medium line of the tread band placed in correspondence with the footprint area substantially parallel to the ground. A tyre and a wheel for motor-vehicles, wherein the medium line of the tread band and the rotation axis of the tyre form an angle substantially equal in absolute value to the camber angle. A process for manufacturing such tyres, wherein a green tyre with symmetric outer profile is deformed during the vulcanising and moulding step until a predetermined angle different from zero is formed between any medium line of the tread band and the rotation axis of the vulcanised tyre.

摘要： A tyre for a vehicle wheel comprising two sidewalls, a tread, beads, the sidewall intended to be positioned on the interior side of the vehicle being shorter than that intended to be positioned on the exterior side of the vehicle, a reinforcement structure extending between the beads and maintained in said beads by anchoring zones, each of the beads comprising a specific and distinct arrangement of the anchoring zone thereof, such that the anchoring zone of the bead intended to be positioned on the exterior side of the vehicle exhibits a greater anchoring capacity than the anchoring zone of the bead intended to be on the interior side of the vehicle. The internal and external anchoring zones are thus arranged in such a manner as to produce, in operation, a rim clamping load which is substantially identical on each side.
