A tire for an agricultural vehicle, and in particular its tread, which aims to increase its traction capability in the field on loose ground. The tire having a nominal section width L, a central tread portion (211), centred on an equatorial plane (E) of the tire and having an axial width L1 at least equal to 0.15*L and at most equal to 0.35*L, has circumferentially distributed tread pattern elements (221), which are separated in pairs by transverse voids (231) forming an angle at least equal to 30° with the circumferential direction (XX′), and the central tread portion (211) has a local volumetric void ratio TEVL1, defined as being the ratio between the volume VC1 of the transverse voids (231) and the total volume V1 of the central tread portion (21), between the bearing surface (24) and the tread surface (25), is at most equal to 15%.
