<p>An object is to provide a pneumatic tire having an enhanced high-speed durability without deterioration in steering stability. A pneumatic tire 10 includes a belt 14 and a tread section 16 on an outside of a crown part 12C in this order, and has different negative ratios of the tread section 16 between both sides of a tire equatorial plane 10C. A belt width Ba from a belt end 14I on the higher negative ratio side to the tire equatorial plane 10C and a belt width Bb from a belt end 14E on the lower negative ratio side to the tire equatorial plane 10C satisfy a relationship of Ba>Bb. It is thereby possible to efficiently suppress a shoulder section 18 from projecting due to a centrifugal force during high-speed rolling. It is thereby possible to efficiently reduce a strain and a heat generated in a rubber member of the shoulder section 18, and efficiently enhance high-speed durability. Further, by ensuring that a grounding width on an OUT side is equivalent to that of a conventional one, it is possible to prevent deterioration in steering stability. <IMAGE></p> |
