Patent number: 11241918Abstract: A pneumatic tire comprises an inner circumferential groove and an outer circumferential groove in a tread portion and extending in a tire circumferential direction. A land portion between circumferential grooves is defined by the inner and outer circumferential grooves. The pneumatic tire includes first and second auxiliary grooves disposed in the tire circumferential direction that communicate with the inner and outer circumferential grooves, respectively, and terminate within the land portion between circumferential grooves. The first auxiliary grooves and the second auxiliary grooves have a non-intersecting, alternating arrangement. At least one narrow groove is disposed between adjacent first auxiliary grooves. At least two narrow grooves are disposed between adjacent second auxiliary grooves. The at least two narrow grooves between second auxiliary grooves are disposed in a greater number than the number of the at least one narrow groove between first auxiliary grooves.Type: GrantFiled: August 27, 2015Date of Patent: February 8, 2022Inventor: Naoko Suzuki
