Each groove of the first plurality of grooves has a substantially curvilinear course such as to form a concavity. The central portion further includes a sub-portion substantially free of grooves placed astride the equatorial plane of the tyre. Each of the shoulder portions includes a second plurality of grooves arranged obliquely relative to the equatorial plane of the tyre.
