In tread-width-direction cross section under a standard internal pressure and no load condition, a point B is an outermost point of overlapping area in tread-width-direction, a line CC is a line passing through an outermost point C′ of carcass layer in tread-width-direction and extending along tread-width-direction, a point C is a point of tire surface through the line CC, a line segment BW is a line segment extending in tread-width-direction from an equator center line to point B, a line segment CW is a line segment extending along tread-width-direction from equator center line to point C, and a line segment BC is a line segment connecting between point B and C. A ratio BW/CW between a length of BW and CW is not less than 0.6 and not more than 0.8. An angle &thetas; formed by BC and CW is not less than 50° and not more than 70°. |
