    摘要： A pneumatic tire having a rubber tread of a cap/base construction comprising a rubber tread cap layer (3) containing an outer running surface (4) and a rubber tread base layer (5) at least partially or fully underlying the rubber tread cap layer (3) is disclosed. The tread cap layer (3) comprises at least two circumferential, longitudinal rubber tread cap zones (11, 12). The first tread cap zone (11) and the second tread cap zone (12) each independently comprising a vulcanizable rubber composition comprising 30 to 70 parts by weight, per 100 parts by weight of elastomer (phr) of a first styrene-butadiene rubber having a Tg in a range of from -40ºC to -20ºC; 30 to 70 phr of a second styrene-butadiene rubber having a Tg in a range of of from -30ºC to -5ºC; 40 to 60 phr of a low PCA process oil and 15 to 35 phr of a resin, wherein the total amount of oil and resin ranges from 55 to 75 phr; and carbon black and silica in a combined amount of from 100 to 150 phr. At least one of the first and second styrene-butadiene rubbers has a weight average molecular weight greater than 1,000,000. The first styrene-butadiene rubber and the second styrene-butadiene rubber have a difference in Tg in a range of from 10 °C to 20 °C. The weight ratio of silica to carbon black in the rubber composition of the first tread cap zone (11) is in a range of from 4:1 to 6:1 and the weight ratio of silica to carbon black in the rubber composition of the second tread cap zone (12) is in a range of from 0.7:1 to 1.3:1.

    摘要： A pneumatic tire (100) having a tread (120) terminating in a pair of shoulders (140), a carcass structure (220) comprising at least one carcass ply (240, 260), two bead regions (180), two sidewalls (160), each sidewall (160) having an upper sidewall portion that connects to the shoulders (140), a belt structure (300) between the tread (120) and the carcass structure (220), and an air impermeable inner liner (400) located radially inward of the carcass structure (220) is disclosed. The inner liner (400) is either (i) formed of a butyl rubber and extends from the first shoulder to the second shoulder underneath the crown portion of the tire, wherein the inner liner (400) does not extend from the shoulders (140) to the bead regions (180) of the tire (100); or (ii) is formed of two zones (410, 420), wherein in the first zone (420) the inner liner (400) comprises or is made of a butyl rubber, the first zone extending from the first shoulder to the second shoulder underneath the crown portion of the tire, and wherein in the second zone (410) the inner liner (400) does not comprise butyl rubber or comprises butyl rubber but at a butyl concentration less than in the first zone (420), the second zone (410) extending from each of the shoulders (140) to the respective bead region (180) of the tire (100).
