Tyre comprising a tread formed by multiple elastomer blends |
摘要 |
The invention relates to a tyre including a radial carcass ply. The tyre comprises a crown ply capped radially with a tread connected to two beads by means of two sidewalls, said tread comprising at least two radially-stacked layers of elastomer blends and having a lower grooving rate in the centre than at the axially outer portions thereof. A first elastomer-blend layer of the tread is formed by a first elastomer blend forming a portion that extends at least in the area of the mid-plane and by at least two axially outer portions formed by a second elastomer blend, in which the first elastomer blend has a macro dispersion score Z above 65 and a maximum tan(delta) value, denoted tan(delta)max, below 0.150 and the second elastomer blend has a maximum tan(delta) value, denoted tan(delta)max, below 0.130. |
