A tread (5) of a tire (1) which has a carcass reinforcement (2) and is reinforced by a reinforcement belt (3), the tread, comprising a so-called rolling surface (6), being divided into at least one circumferential strip. Each defined circumferential strip is provided with a plurality of incisions (71) of small length in transverse direction. On each defined circumferential strip a circumferential notching ratio is defined which makes it possible to reduce the amount of energy dissipated by deformation upon the rolling of the tire.
