ABSTRACT:
A pneumatic tire has a tread portion (11) which consists of a plurality of block elements (17) arranged in rows (18) extending laterally across the tread portion. In each row each block element (17A) axially overlaps with at least one adjacent block elment (17B) and (17C). The mutually overlapping portions of the block elements (17) are separated by axially extending blades (26).
Under a circumferential load (L), the block elements distort and the blades close so that adjacent blocks interlock.
