The invention provides an aerated tyre which has a wear-resistant property and can be used on a wet road. The tread part (2) comprises a central main groove (3) which continuously extends along the circumferential direction of the tyre; a pair of tyre shoulder main grooves (4) which are arranged on the two sides of the central main groove (3) and continuously extends along the circumferential direction of the tyre; a pair of central land parts (5), which are arranged between each tyre shoulder main groove (4) and the central main groove (3); and a pair of tyre shoulder land parts (7), which are arranged between each tyre shoulder main groove (4) and a tread landing end (Te). The central land parts have a plurality of central horizontal grooves (8) that communicate the central main groove and the tyre shoulder main grooves (4) and are axially inclined relative to the tyre and a central patterned block (50), which is roughly in a rhomboid shape. The length ratio (La/Lb) of the length (La) of the central patterned block in the circumferential direction to the length (Lb) of the central patterned block in the axial direction is 0.8 to 1.1. The tyre shoulder land parts (7) are composed of ribs that continuously extend in the circumferential direction of the tyre. |
