The invention relates to a reinforced tire tread. A tire tread region has a first block element and a second adjacent block element spaced apart by a groove and a reinforcement bar is situated within the groove. The reinforcement bar extends between the first and second adjacent blocks at a prescribed inclination angle from a deeper surface end within the groove to a radially more shallow opposite surface end. The inclined surface includes a radially outwardly facing concave surface portion at the radially inward, deeper, inclined surface end.
