摘要： A pneumatic tire 1 includes a plurality of main grooves 21 and 22 extending in a tire circumferential direction and at least four ribs 31 to 33 sectioned by the main grooves 21 and 22 on a tread portion. The main groove in the outermost position in a tire width direction out of the main grooves 21 and 22 is an outer main groove 22. Sipes 311 to 332 formed across edge portions of the ribs 31 to 33 on both sides are open sipes. Sipes 323 and 333 formed on the edge portions of the ribs 31 to 33 on one side are multisipes. The open sipes 311 to 332 are formed on the ribs 31 to 33, the multisipes 323 and 333 are formed on only the ribs 32 and 33 between which the external main groove 22, and the multisipes 323 and 333 are aligned along the edge portions of the rib 32 and 33.
