<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire having a color layer with improved contamination resistance. <P>SOLUTION: In the pneumatic tire, a color layer is formed via a barrier layer on the lateral outside of a side part of the tire. A difference between a solubility parameter (SP value) of a main component polymer of the barrier layer and that of a contaminated component contained in an adjacent rubber is 5.0 or more. A difference between a solubility parameter (SP value) of a sub component polymer contained in the barrier layer and that of the contaminated component contained in the adjacent rubber is in the range of 0-5.0. <P>COPYRIGHT: (C)2013,JPO&INPIT |
