Abstract:
In a pneumatic tire, a belt layer includes an inner-side cross belt and an outer-side cross belt having an absolute value of belt angle with respect to a tire circumferential direction of not less than 46 degrees and not more than 80 degrees and having belt angles with signs that are opposite to each other; and a circumferential reinforcing layer having a belt angle with respect to the tire circumferential direction within the range of ±5 degrees and disposed between the inner-side cross belt and outer-side cross belt. Also, a distance Gcc on a tire equatorial plane from a tread profile to a tire inner circumferential surface and a distance Gsh from a tread edge to the tire inner circumferential surface satisfy a relationship 1.10≦Gsh/Gcc.
