Abstract
A tread having a plurality of grooves formed on each half of the tread on each side of a midplane X-X′, each opening axially to the outside and extending axially towards the midplane X-X′ so that the plurality of grooves forms a first pattern in the overall shape of a V pointing in a groove direction Xr. The tread includes a plurality of sipes. From a certain degree of wear onwards, all or some of the sipes become enlarged forming cavities extending in an oblique direction forming a second pattern in the overall shape of a V pointing in a cavity direction Xc. Each of these cavities opens into just one of the grooves of the tread, the plurality of grooves forming, at this level of wear, the same first pattern.
