Abstract
Official abstract text for this publication.
A pneumatic tire is mounted on a vehicle so a first side in a tire width direction corresponds to a vehicle outer side. A tread surface has four circumferential main grooves extending in a tire circumferential direction and five land portions partitioned by the circumferential main grooves. A ratio W 2 /W 1 ranges 4 to 5 when W 1 is a groove width of a first circumferential main groove that is located at a first position when viewed from the first side and W 2 is defined as a groove width of a second circumferential main groove located at a second position when viewed from the first side, and a ratio S in /S out ranges 1.1 to 1.2 when, in a region of the tread surface which interposes the tire centerline, S out is defined as a groove surface area ratio in a region on the first side and S in is defined as a groove surface area ratio in a region on the second side.
First claim
Opening claim text (preview).
The invention claimed is: 1. A pneumatic tire that mounts on a vehicle so that, when the pneumatic tire is mounted, a first side in a tire width direction corresponds to a vehicle outer side and a second side that is an opposite side of the first side in the tire width direction corresponds to a vehicle inner side, wherein a region of a tread surface of the pneumatic tire includes: four circumferential main grooves extending in a tire circumferential direction; five land portio…
