Abstract
Official abstract text for this publication.
Tire ( 10 ) comprising a tread ( 40 ) having a mean radial height HB, an outer edge ( 45 ) and an inner edge ( 46 ), the axial distance between the outer edge ( 45 ) and the inner edge ( 46 ) defining the axial width L of the tread, the tread comprising a first portion ( 411 ) made of a first rubber compound, extending from the outer edge ( 45 ) to a first axial position at an axial distance from the outer edge of between 20% and 40% of the axial width; a second portion ( 412 ) made of a second rubber compound, extending from said first axial position to a second axial position at an axial distance from the outer edge of between 50% and 60% of the axial width L; a third portion ( 413 ) made of a third rubber compound extending from said second axial position to a third axial position at an axial distance from the outer edge of between 80% and 90% of the axial width L; and a fourth portion ( 414 ) made of a fourth rubber compound, extending from said third axial position to the inner edge ( 46 ) of the tread, wherein said first and third rubber compounds are predominantly filled with carbon black filler, wherein said second and fourth rubber compounds are predominantly filled with non carbon black filler, and wherein said first rubber compound and said third rubber compound have a value for tan δ at 0° C., at a stress of 0.7 MPa, that is lower than that of said second rubber compound and said fourth rubber compound.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tire designed to be mounted on a mounting rim of a wheel of a vehicle and having a predetermined direction of mounting on the vehicle, comprising: a tread having a mean radial height HB, comprising a rolling surface designed to come into contact with a ground when the tire is rolling on the ground, the tread having an outer edge and an inner edge, the outer edge being situated on that side of the tire which, when the tire is mounted on the vehicle in…
