摘要： A pneumatic tire for improving steering stability performance on dry and wet road surfaces. The tire tread pattern has circumferential center main grooves, outside and inside main grooves, land sections demarcated by the main grooves, ground contact borders on both sides of the tire, and closed shoulder lug grooves. A ratio Wmax/Wout of a maximum main groove width Wmax and an outside main groove width Wout is at between 1.5 and 2.5 inclusive. A ratio Sin/Sout of a groove area ratio Sin of a region on a tire-widthwise second side of a tire centerline and a groove area ratio Sout of a region on a first side of the tire centerline is at least 1.10 and smaller than 1.25. A groove area ratio of a region on the second side of a tire-widthwise centerline of the intermediate land sections exceeds that of a region on the first side.

摘要： A pneumatic tire including a plurality of circumferential main grooves extending in a tire circumferential direction and a plurality of land portions partitioned and formed by these circumferential main grooves in a tread portion. Additionally, the plurality of land portions have a plurality of sipes, respectively. Moreover, not less than 90% of the sipes disposed in an inner side region are constituted by two-dimensional sipes and not less than 90% of the sipes disposed in an outer side region are constituted by three-dimensional sipes. Furthermore, the tread portion has a cap rubber and an under rubber. A rubber hardness H1in at −10° C. and a rubber hardness H2in at 20° C. of the cap rubber 151in in the inner side region, and a rubber hardness H1out at −10° C. and a rubber hardness H2out at 20° C. of the cap rubber 151out in the outer side region have relationships such that H1in
