1. A method of preparing a sidewall support, the method comprising the steps of:
(i) providing a vulcanizable composition including an elastomer, a filler, a curative, an antioxidant, and a eutectic composition, where the eutectic composition is defined by the formula Cat+X−zY, where Cat+ is a cation, X− is a counter anion, and z refers to the number of Y molecules that interact with the counter anion, where the counter anion is a Lewis Base;
(ii) fabricating the vulcanizable composition into a green sidewall support; and
(iii) subjecting the green sidewall support to curing conditions.
