To reduce noise while suppressing increase in rolling resistance, without affecting the formation of a carcass line, provided is a pneumatic tirecomprising an inner liner. The thickness of the inner linerat least in part of a side portionis 1.5 mm or more. When the tireis 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&#x2265;2.135&#xd7;SW+282.3.

Pneumatic tire

To reduce noise while suppressing increase in rolling resistance, without affecting the formation of a carcass line, provided is a pneumatic tire () including: a carcass (); an inclined belt (), and an inner liner (). The inclined belt () is disposed on the tire radial outer side of the crown portion of the carcass (). The inclined belt () includes at least one inclined belt layer (). The inclined belt layer () has cords extending as being inclined at 35&#xb0; or more with respect to the tire circumferential direction. The inner liner () has a thickness of 1.5 mm or more at least in part of a side portion ().
