摘要： A pneumatic tire improved in on-ice performance and on-snow performance in good balance. The pneumatic tire includes a tread portion extending in a tire circumferential direction and forming a ring shape, a pair of sidewall portions on both sides of the tread portion, respectively, and a pair of bead portions on inner sides of the sidewall portions in a tire radial direction, respectively. The tread portion includes a plurality of longitudinal grooves extending in the tire circumferential direction and a plurality of lateral grooves extending in a tire width direction. The longitudinal and lateral grooves define a plurality of block rows each including a plurality of blocks. Each of the plurality of blocks included in at least one of the block rows includes at least three closed grooves including at least one first closed groove and at least one second closed groove.

摘要： Provided is a run flat tire having an enhanced ride comfort in running on general road surfaces and an enhanced driving stability on snowy road surfaces at the time when the tire is not punctured, as well as an enhanced maneuverability, particularly starting ability, on icy road surfaces in run-flat running where the tire is punctured. Three belt layers (8, 9, 10) are disposed on an outer circumferential side of a carcass layer (6) in a tread portion (4). In addition, as to the three belt layers, the cord angle α of the innermost belt layer (8) with respect to a circumferential direction of the tire is set at 15° to 30°, the cord angle β of the intermediate belt layer (9) with respect to the circumferential direction of the tire is set at not less than 40°, and the cord angle γ of the outermost belt layer (10) with respect to the circumferential direction of the tire is set at 35° to 70°.
