摘要： A pneumatic tire with a noise damper has a noise damper made of porous resin foam and arranged on a tread inner surface. The noise damper is formed by a single annular body extending continuously in a tire circumferential direction. The noise damper has a core density in a range of from 35 to 65 kg/m3 and an overall density in a range of from 50 to 105 kg/m3. A maximum height of the noise damper from the tread inner surface is in a range of from 12 to 30 mm.

摘要： A pneumatic tire can have a tread portion. A sponge-like sound absorbing member can be attached to an inner surface of the tread portion. The sound absorbing member can have an outer peripheral surface facing outward in a tire radial direction. A plurality of grooves, and a plurality of land portions separated from each other by the plurality of grooves, can be formed in the outer peripheral surface. Each of the plurality of grooves can have an opening width at the outer peripheral surface larger than a groove bottom width of the groove in a cross-section thereof perpendicular to a longitudinal direction of the groove.

摘要： A pneumatic tire is provided with a noise damper made of a sponge material attached to a radially inner surface of the tread portion. The noise damper has protruding portions protruding from a radially inner surface of a band-shaped base portion. The protruding portions extend from one edge to the other edge of the base portion in the widthwise direction, and arranged at intervals in the tire circumferential direction. In a cross section of the tire parallel with the tire equatorial plane, the radially inner surface of each of the protruding portions includes a flat portion, and the radially inner surface of the base portion includes an arc portion parallel with the inner surface of the tread portion.

摘要： A pneumatic tire comprises a tread portion provided on each side of the tire equator with a middle land portion defined between a shoulder main groove and a crown main groove each extending continuously in the tire circumferential direction. The middle land portion is provided with axially inside middle lug grooves and axially outside middle lug grooves arranged alternately in the tire circumferential direction. The axially inside middle lug groove is connected to the crown main groove at an angle θ1 of from 20 to 45 degrees with respect to the tire circumferential direction and has an axially inner opened end and an axially outer closed end. The outside middle lug grooves is connected to the shoulder main groove at an angle θ2 of from 60 to 80 degrees with respect to the tire circumferential direction and has an axially outer open end and an axially inner closed end. The tread portion may be provided with a shoulder land portion comprising circumferential sipes, axial grooves terminating at the circumferential sipes, and a circumferentially continuous rib.
