ABSTRACT:
A pneumatic tire comprises a tread portion provided with tread grooves each having a bottom and sidewalls, the tread grooves provided with ejectors for preventing stone trapping. The ejectors protrude from the groove bottom independently of the sidewalls, the ejectors having a substantially triangular shape. The tread grooves comprise a main groove extending continuously in the tire circumferential direction, and the triangular ejectors are disposed in wide portions of the main groove. The wide portion has sidewalls flaring toward the center line of the main groove, and the triangular ejector disposed therein has two sides substantially parallel to the flaring sidewalls, respectively. The main groove is further provided with a continuous ejector extending along the length of the main groove, or a series of independent rectangular ejectors arranged along the length of the main groove at intervals.
