Abstract
Disclosed herein, a pneumatic tire having a tread portion is described. The tread portion includes a generally circumferentially extending groove defined therein. The groove has a groove cross-section defined by a groove bottom, a first groove sidewall, hand a second groove sidewall. The second groove sidewall is opposite and substantially parallel to the first groove sidewall. The groove has a groove width defined between the first groove sidewall and the second groove sidewall. A plurality of stone rejectors extend between the first groove sidewall and the second groove sidewall. Each stone rejector in the plurality of stone rejectors is circumferentially spaced from an adjacent stone rejector. Each stone rejector includes a raised platform and a protrusion. The raised platform extends axially from the first groove sidewall to the second groove sidewall. The protrusion extends from a top surface of the raised platform.
