<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire that is suitable for loading in a general vehicle, such as a passenger car, and also superior in uneven wear resistance, while reducing rolling resistance and achieving lightweight. <P>SOLUTION: The pneumatic tire includes a carcass layer 5 consisting of at least one sheet of carcass ply 5a which toroidally extends and a belt layer 6 arranged on the outside of the carcass layer 5. The belt layer 6 includes: a first belt 7 which has a first cord 7a tilted at an angle to equator S in the range of 15-75°; and a second belt 8 which has a second cord 8a extending in parallel to the equator S. In the second belt 8, the relation of 0.003<δ/Rs<0.02 is fulfilled, wherein Rs is taken as a radial direction length from an axis of the tire to the center in the width direction of the second belt 8; Re is taken as a radial direction length from an axis of the tire to the outermost end in the width direction of the second belt 8; and δ is taken as a difference of the radial direction length Rs and the radial direction length Re. <P>COPYRIGHT: (C)2012,JPO&INPIT |
