<p><P>PROBLEM TO BE SOLVED: To provide a tire which enables a driver and the like to more reliably recognize progress conditions of tire wear when the progress conditions of the tire wear are indicated by a change in tread surface color. <P>SOLUTION: The pneumatic tire 10 includes a color rubber 120 which configures a part of a tread 20 and which has a color different from a color of other parts of the tread. The color rubber 120 is continuously provided in the circumferential direction D<SB POS="POST">C</SB>of the tire, and provided in a predetermined area on the inside in the radial direction D<SB POS="POST">R</SB>of the tire with respect to the wheel tread of the tread 20. The color rubber 120 has its width in the width direction of the tread varied toward the inside in the radial direction D<SB POS="POST">R</SB>of the tire, in a cross-section along the width direction D<SB POS="POST">T</SB>of the tread and the radial direction D<SB POS="POST">R</SB>of the tire. A shape of the color rubber 120 in a position at an inside end in the radial direction of the tire is more linear than at an outside end in the radial direction of the tire along the circumferential direction of the tire, in a plan view of the tread. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
