<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of stably reducing noise without causing a land part to tend to be lost irrespective of change in use conditions. <P>SOLUTION: A pneumatic tire 1 is formed with circumferential grooves 11 extending in its tire circumferential direction S and lug grooves 12 extending in its tire width direction H on its tread portion 10, the circumferential grooves 11 and the lug grooves 12 dividing the outer surface of the tread portion 10 into a plurality of land parts 16 to 18. Formed at least at one of both ends of the land parts 16 to 18 in the tire circumferential direction S is an raised portion 14 projecting outward in the tire diametrical direction from a virtual profile line L formed by elongating outward in the tire circumferential direction S the upper surface of the central section in the tire circumferential direction S in the land parts 16 to 18. The projection height c of the raised portion 14 formed in a shoulder land part 18 located outermost in the tire width direction H of a plurality of land parts 16 to 18 is higher than the projection height c of the raised portion 14 formed in a center land part 16 located innermost in the tire width direction H. <P>COPYRIGHT: (C)2012,JPO&INPIT |
