Japanese Patent JP2010247778
Kind Code:

Abstract:

To provide a pneumatic tire capable of reducing rolling resistance in the case that a range where a belt layer is arranged is narrower than the width of a tread part in a tread width direction.

In the pneumatic tire 1, in a cross section in the tread width direction, an angle θ formed by a belt end inclined line BQ connecting an end part B of an outside belt layer 32 and a tire maximum width position Q and a maximum width passing line SW connecting a pair of tire maximum width positions Q is equal to or smaller than 50°. In the cross section in the tread width direction section area, a bead filler height XY parallel with a tire equator line CL from an inside end part X of a bead core 12 to an outside end part Y of a bead filler 13 is 15-40% for a tire height SH parallel with the tire equator line CL from a toe passing line M including a pair of bead toes 11 to an outer most position G of the tread part 40.
