Pneumatic tire
Abstract:
A pneumatic tire comprising a tread portion provided with a middle land portion 6 which is arranged between a central main groove 3 and a shoulder main groove 4. The middle land portion 6 is provided with an inner middle lateral groove 8 and an outer middle lateral groove 9. The inner middle lateral groove 8 comprises a first inclined portion 10 that extends axially outwardly from the central main groove 3 at an angle θ1 of from 10 to 40 degrees with respect to a circumferential direction of the tire, and a second inclined portion 12 that is inclined at an opposite direction to the first inclined portion 10 so as to extend axially inwardly, and a bent portion 11 connecting the first inclined portion 10 and the second inclined portion 12. The outer middle lateral groove 9 is communicated with the second inclined portion 12 of the axially inner middle lateral groove 8 without including an axially outermost groove edge 8e of the inner middle lateral groove 8, and is communicated with the shoulder main groove 4. The axially outer middle lateral groove 9 is inclined in the same direction of the first inclined portion 10 of the inner middle lateral groove 8 at an angle θ3 of from 30 to 70 degrees with respect to the circumferential direction of the tire.
