Pneumatic tire

Car tire has circumferential grooves (1, 1', 1", 3, 3') in its tread bands (2, 2', 22, 7, 7', 7"). Its inner section (I) is divided into offset blocks (8a, 8'a) by additional circumferential grooves (9, 9') and transverse grooves (10, 10') which are deeper than the grooves (1, 1', 1") along the edges of the blocks. The outer section (A) of the tire is free from transverse grooves except at the shoulder.
