PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving wear resistance without sacrificing wet performance and steering stability.SOLUTION: In a middle land portion 12, middle sipes 15, middle lateral grooves 16, and the like are formed. In a shoulder land portion 13, shoulder lateral grooves 18, shoulder sipes 19, and the like are formed. A ratio Ems/Ema of a total Ems of tire-axial-direction components of edge lengths of the middle sipes 15 or the like to a total Ema of tire-axial-direction components of edge lengths of the middle sipes 15, etc., the middle lateral grooves 16 or the like is set lower than a ratio Ess/Esa of a total Ess of tire-axial-direction components of the edge lengths of the shoulder sipes 19 or the like to a total Esa of the tire-axial-direction components of the edge lengths of the shoulder sipes 19, etc., the shoulder lateral grooves 18 or the like. By so setting, it is possible to increase a BR component amount in tread rubber and dramatically improve wear resistance without sacrificing wet performance. |
