<p>To provide a pneumatic tire that can improve a rollover resistance while retaining a driving stability, a tread surface 11 is formed from a center arc 31, a shoulder-side arc 32, and a shoulder arc 33. Moreover, the tread surface 11 is formed in such a manner that a value obtained from a relation K1=L1/(TDW×0.5) satisfies 0.6‰ K1‰ 0.8, where K1 is a relation between an outline area L1 that is a width from an equatorial plane 5 to the end of the center arc 31 and a tread development width TDW, and a ratio K2 satisfies 0.9‰ K1‰ 2.0, where K2=TR1/OD, and K2 is a ratio of a curvature radius TR1 of the center arc 31 to a tire outside diameter OD. Furthermore, the tread surface 11 is formed in such a manner that a value obtained from a relation K3=(²×TDW)/(100×SW) satisfies 0.40‰ 3‰ 0.48, where k3 is a relation between an aspect ratio ², the tread development width TDW, and a total width SW. As a result, the rollover resistance can be improved while retaining the driving stability.</p> |
