| description | PROBLEM TO BE SOLVED: To improve the wet performance and noise performance in a well balanced manner while maintaining steering stability. SOLUTION: A middle rib 9 is divided into an inner middle part 10 and an outer middle part 11 by a middle sub groove 5 continuously extending in a tire circumferential direction. Inner middle lug grooves 15 that start at the middle sub groove 5 and terminate without communicating with a crown main groove 3 are provided at the inner middle part 10 to be apart with each other in the tire circumferential direction. The inner middle lug groove 15 includes an inner lug main part 15a that is formed on the middle sub groove 5 side and of which the groove width is 1.5 mm or more, and an inner sipe-shaped part 15b that is formed on a tire equator C side. Outer middle lug grooves 16 that start at a shoulder main groove 4 and terminate without communicating with the middle sub groove 5 are provided at the outer middle part 11 to be spaced with each other in the tire circumferential direction. The outer middle lug groove 16 includes an outer lug main part 16a that is formed on the shoulder main groove 4 side and of which the groove width is 2.0 mm or more, and an outer sipe-shaped part 16b that is formed on the tire equator C side.
