A retreaded pneumatic truck tire includes a used carcass having a uniform annular attachment area and a retread element. The retread element secures to the attachment area of the used carcass. The retread element has a tread pattern comprising a first circumferential groove separating the tread pattern into a first shoulder rib and an intermediate rib and a second circumferential groove separating the tread pattern into the intermediate rib and a second shoulder rib. The tread pattern further comprises a first plurality of identical arcuate notches extending axially and circumferentially across the first circumferential groove and a second plurality of identical arcuate notches extending axially and circumferentially across the second circumferential groove. The first plurality of arcuate notches are offset circumferentially from the second plurality of arcuate notches.
