Abstract
A pneumatic tire () having a sound absorption effect by lateral grooves is provided. The tire tread () has circumferential grooves formed continuously in the circumferential direction and lateral grooves extending from a circumferential groove. One end of each lateral groove is connected to the circumferential groove and the other end is a dead end. Each of the lateral grooves () includes a one-directional groove () extending in one direction from the circumferential groove () toward a side edge of the tire and an another-directional groove () extending in another direction from the circumferential groove toward the side edge of the tire. A root section (), which is close to the circumferential groove, of the one-directional groove () and a root section (), which is close to the circumferential groove (), of the another-directional groove () are formed by a common groove (). And a leading part () of the one-directional groove () and a leading part () of the another-directional groove () are branching away from each other from a leading end of the common groove ().
