TIRE TREAD AND TIRE WITH SUCH A TREAD

A tread for a tire (10) and a tire (10) comprising such a tread (11) is disclosed. The tread (11) comprises a circumferential groove (22) having a radially outermost and axially inner first groove edge (240) and a radially outermost and axially outer second groove edge (241). A centerline (227) or center plane of the circumferential groove (22) extends circumferentially along the circumferential groove (22) and axially in the middle between the first and second groove edge (240, 241). The circumferential groove (22) comprises a stabilizing structure (220) for increasing tread stiffness. The stabilizing structure (220) is axially offset a predetermined amount from the centerline (227) or center plane of the circumferential groove (22). The circumferential groove (22) has an angled axially inner sidewall (161, 171), an angled axially outer sidewall (162, 172), and a curved base surface (163, 173). The stabilizing structure (220) extends radially inward of the curved base surface (163, 173).
