ABSTRACT OF THE DISCLOSURE A novel pneumatic tire is provided which has a tread region and a pair of shoulder regions. The tread region is provided with a pair of circumferentially extending shoulder ribs. One shoulder region is extended radially inwardly from each tread edge. The shoulder regions are each provided with buttress hollows arranged circumferentially at intervals. At least one of the should ribs is provided with circumferentially-extending narrow grooves. Each of the narrow grooves comprise a long main portion, a short overlap portion and an inclined portion extending therebetween to connect the overlap portion with the main portion. The main portion and the overlap portion extend in parallel to the circumferential direction of the tire. The inclined portion is inclined with respect to the circumferential direction of the tire and connects the overlap portion with the main portion. The narrow grooves are arranged in the circumferential direction of the tire so that the circumferentially-adjacent narrow grooves are overlapped with each other at their end portions. The locations of the overlaps in the narrow grooves are coincident with the locations of the buttress hollows in the circumferential direction of the tire.
