Tire with asymmetric evolutionary design sculpture

摘要

Tire of private vehicle comprising a tread extended on each side by side.In this tread is provided with a drawing of the sculpture is asymmetrical in relation to a median plane that divides the band into two parts of the same axial.And the axial width is measured in a direction parallel to the geometric axis of rotation, an outer part and an inner part.In the external part is located between the median plane and the side intended to be placed on the exterior of a vehicle.And the inner part is located between the plan and the flank to be placed facing to the interior of the vehicle; the inner part and the outer part, include each.At least one indentation that forms a groove or destined to form a groove after a partial wear of the band; these recesses define, in the new state and for each part (internal and external)A total volume of indentation, respectively vi0 and ve0, a rate of indentation of the surface respectively you, okay? And TE0, and these rates are different from zero, and so.In the new state, if a relation R0 between the indentation of the inner volume and the volume of indentation of the external part, and,Each state of wear (U) selected from the initial state and the limit of wear of the band.It is a relationship between the volume of indentation of the UK internal part and external part, the volume of indentation, and the tire is distinguished by the fact that,At least from 80% of wear measured in thickness of band to be worn, the reason the UK is larger than the ratio R0.
