Document Type and Number:
WIPO Patent Application WO/2023/105832
Kind Code:
A1
Abstract:
The pneumatic radial tire for a passenger vehicle according to this invention has a cross sectional width SW and an outer diameter OD satisfying a predetermined relationship and comprises one or more circumferential main grooves which extend in the tire circumferential direction in a contact surface of a tread. The negative ratio of a half portion on one side in the tread width direction, which is on the outside when the tire is mounted to the vehicle and has the tire equatorial plane as a boundary, is larger than the negative ratio of a half portion on the other side in the tread width direction, which is on the inside when the tire is mounted to the vehicle and has the equatorial plane as the boundary. Moreover, a drop height (or a ground contact length relationship or a tread gauge relationship) is set to a predetermined value.
