摘要： Provided are pneumatic tires or studless winter tires that achieve a balanced improvement in fuel economy, reinforcing properties (flex crack growth resistance, abrasion resistance, tensile strength, adhesive strength, resistance to air permeation), grip performance (wet-grip performance, performance on snow and ice), handling stability, and heat aging resistance, and methods for producing such a pneumatic tire or studless winter tire. The present invention relates to a pneumatic tire including at least one component selected from the group consisting of a sidewall, a base tread, a bead apex, a clinch apex, an innerliner, and an undertread, each of which is formed from a rubber composition that contains a highly purified, modified natural rubber whose pH is adjusted to 2 to 7, and carbon black and/or a white filler.
