A pneumatic tire has a block pattern which is divided by plural circumferential grooves extending in the circumferential direction of a tire and a number of lateral grooves crossing the circumferential grooves. In the block pattern, the block circumferential/lateral ratio Lm/Wm of the average block circumferential length Lm to the average block width Wm is in a range from 0.38 to 0.55, and the block circumferential length ratio Lm/L of the average block circumferential length Lm to the circumferential length L of the tread part is in a range from 1/120 and to 1/85.
