PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of reducing cavernous resonance, facilitating a flat tire repair using a flat tire sealant, and ensuring low flat tire position dependence of flat tire repair efficiency.SOLUTION: A width of the belt 5 formed of not less than one belt layer provided on a tread part 3 in a tire width direction is BW, and a region between a position B on a tire inner circumferential surface closer to a center in the tire width direction by BW×0.1 from a tire width position corresponding to an outside end of the belt in the tire width direction and a midpoint position C of a tire inner circumferential length between the tire width position A and a tire maximum width position MW is a buttress part inner circumferential surface BR. In this case, short fibers 10 are fixedly attached to at least a part of the tire inner circumferential surface, an attachment area rate of the short fibers 10 on the entire tire circumferential surface is not less than 70%, and an attachment area rate of the short fibers 10 on at least one buttress part inner circumferential surface BR out of a pair of buttress part inner circumferential surfaces BR is not more than 50%. |
