PROBLEM TO BE SOLVED: To provide a pneumatic tire having a tread pattern which improves snow traction performance while maintaining brake and drive performance on a dry road.SOLUTION: A first and a second lug grooves are provided, passing in the tire width direction a first land part which is formed by two main grooves among three main grooves mounted in a tread pattern and over which the tire center line passes. The first and the second lug grooves pass with inclination in a different direction against the tire center line. The first lug groove passes across a second land part area other than the first land part area. Furthermore, a third lug groove passes across the second land part area. The second land part is a block formed by partitioning of the third lug groove and the first lug groove, and includes a first block where the second lug groove is blocked on the way and a second block into which the second lug groove is not extended. The snow traction index of the tread pattern is 180 to 220. |
