Abstract

A pneumatic tire having lateral grooves that improve a sound absorption effect. The pneumatic tire has on its tread surface (2) a circumferential groove continuously circumferentially formed in the tread surface (2) and also has lateral grooves extended from the circumferential groove. The lateral grooves are each formed such that one end of the lateral groove is connected to the circumferential groove and the other end is a dead end. Each lateral groove has one groove (11) extending in one direction from the circumferential groove (5) toward a side edge of the tire, and also has the other groove (14) extending in the other direction from the circumferential groove (5) toward the side edge of the tire. A root section (11a), which is close to the circumferential groove (5), of the one groove (11) and a root section (14a), which is close to the circumferential groove (5), of the other groove (14) are constructed from a common groove (15). The front end (11b) of the one groove (11) and the front end (14b) of the other groove (14) are constructed from grooves (19) branched from the front end of the common groove (15).

Description

technical field

[0001] The present invention relates to a groove structure formed on a tire contact patch of a pneumatic tire. Background technique

[0002] There is known a pneumatic tire which has a circumferential groove formed continuously along the circumference of the tire contact surface on the tire contact surface and a transverse groove extending from the circumferential groove, one end of the transverse groove is connected to the circumferential groove, The other end is closed (for example, refer to Patent Document 1, etc.). The structure of the above-mentioned lateral groove has a one-directional groove extending in one direction from the circumferential groove to the tire side edge, and two directions extending from the front end of the one-directional groove to the circumferential direction of the tire ground contact surface in one direction and the other direction. Winged grooves.
