Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire which can ensure good performance on a snowy road and improve performance on an icy road. SOLUTION: A radius of curvature r1 of an outer contour of each subblock 36 partitioned by sipes 28, 30, 32, 34 is set smaller than a radius of curvature R1 of an outer contour of a tread 12, whereby a grounding area is not reduced rapidly due to bending of subblock caused by braking towards the peripheral direction of the tire to improve a coefficient of friction μ on an icy road in the peripheral direction.
