A tread for a pneumatic tyre, the tread comprising a plurality of grooves, the grooves comprising: a groove surface (122); and a plurality of elements (410) spaced from one another in an arrangement on the groove surface (122). Each element (410) has a shape defining a volume, the shape including: a first cross-sectional shape (425) in a plane (420) parallel to the groove surface (122); and a second cross-sectional shape (435) in a plane (430) perpendicular to the groove surface (122). The arrangement comprises a void volume in the spaces between the elements (410) and a void ratio of between 0.5 to 0.75, wherein the void ratio is defined as a ratio of the void volume to the total volume of the elements (410) in the arrangement.
