Abstract: To reduce noise while suppressing increase in rolling resistance, without affecting the formation of a carcass line, provided is a pneumatic tire 10 comprising an inner liner 17. The thickness of the inner liner 17 at least in part of a side portion 18 is 1.5 mm or more. When the tire 10 is mounted to a rim, and an internal pressure of 250 kPa or more is applied to the tire, in a case where a sectional width SW of the tire is less than 165 mm, a ratio of the sectional width SW to an outer diameter OD of the tire, SW/OD, is 0.26 or less; and in a case where the sectional width SW of the tire is 165 mm or more, the sectional width SW and the outer diameter OD of the tire satisfy a relation expression OD?2.135×SW+282.3.

Abstract: To reduce noise while suppressing increase in rolling resistance, without affecting the formation of a carcass line, provided is a pneumatic tire (10) including: a carcass (13); an inclined belt (14), and an inner liner (17). The inclined belt (14) is disposed on the tire radial outer side of the crown portion of the carcass (13). The inclined belt (14) includes at least one inclined belt layer (16). The inclined belt layer (16) has cords extending as being inclined at 35° or more with respect to the tire circumferential direction. The inner liner (17) has a thickness of 1.5 mm or more at least in part of a side portion (19).

Abstract: A pneumatic tire with improved noise performance while preserving the steering stability and rolling resistance includes, on radially outer side of the crown portion of a carcass, an inclined belt consisting of inclined belt layer(s) having cords inclined at an angle of 35° to 90° relative to the tire circumferential direction, a circumferential belt consisting of circumferential belt layer(s) having cords extending along the circumferential direction, and a tread on radially outer side of the circumferential belt. The circumferential belt includes a high rigidity region across the tire equator wherein the circumferential rigidity per unit width is higher at any location thereof than at any location in the remaining regions. The circumferential rigidity per unit width in the remaining regions is constant in the tire width direction or increases toward the high rigidity region.
