    摘要： A pneumatic tire having a tread with an outer surface defined for ground contact is disclosed. The tread has a first tread zone (30) and a second tread zone (40), wherein the first tread zone (30) includes a central portion of the tread and wherein the second tread zone (40) is located laterally adjacent the first tread zone (40), preferably on both lateral sides of the first tread zone (30). The first tread zone (30) is formed of a first rubber compound and the second tread zone (40) is formed of a second rubber compound different from the first rubber compound. The first rubber compound has a G', measured at 100°C, 1 Hz and at 50% strain in the range of from 1.6 to 1.8 MPa and/or the second rubber compound has a G', measured at 100°C, 1 Hz and 100% strain in the range of from 0.75 to 0.90 MPa.

    摘要： Pneumatic tire comprising two annular bead portions having a bead core (2) and a carcass extending between the bead portions through sidewall portions and a tread portion is disclosed. The carcass includes at least two axially inner plies (1A, 1B, 1C, 1D, 1 E) which extend down from the tread and axially inward of the bead core (2), said at least two axially inner plies (1 A, 1 B, 1 C, 1D, 1 E) being wound around the bead core (2) forming respective turn-ups (10A, 10B, 10C, 10D, 10E), each turn-up (10A, 10B, 10C, 10D, 10E) being located axially outward of the bead core (2). The carcass further includes a first axially outer ply (1 F) which extends down from the tread towards the bead core (2) and which is positioned axially outward of the bead core (2). The first axially outer ply (1 F) is separated from at least one of the turn-ups (10A, 10B, 10C, 10D, 10E) by a first spacer layer (200).
