Abstract
Provided is a low noise pneumatic tire in which the noise absorbing member on the inner peripheral surface of the tire is made less likely to be damaged when the pneumatic tire is removed from the rim. The pneumatic tire includes a noise absorbing member of a porous material which is attached to an inner peripheral surface of the tire. In the pneumatic tire, a lubricant is applied to the inner peripheral surface of the noise absorbing member. Alternatively, both end portions, in a tire width direction, of the inner peripheral surface of the noise absorbing member are covered with protective layers harder than the noise absorbing member.
