<P>PROBLEM TO BE SOLVED: To improve breaking durability to projection input of a tread part, without largely increasing weight of a tire. Ž<P>SOLUTION: This tire has a belt and a tread of at least two layers outside in the radial direction of a carcass with the carcass extending in a toroidal shape between a pair of bead cores as a skeleton. The carcass is a waveform in which a carcass cord of an area including a tire equatorial surface has amplitude in the tire radial direction. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
