PNEUMATIC TIRE |
| 摘要 |
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. |

1. A pneumatic tire comprising an inner liner, wherein:
a thickness of the inner liner at least in part of a side portion of the tire is 1.5 mm or more; when the tire 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; andin 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. |
