ABSTRACT:
The invention relates to a pneumatic tire sidewall and to compositions useful therefor. Such elastomeric composition are comprised of a blend of (A) ethylene/propylene/diene terpolymer, (B) rubbery .alpha.-olefin interpolymer, (C) high unsaturation rubber comprised of about 30 to about 80 weight percent natural rubber and (D) especially experimentally selected and manipulated compound additives selected from triallyl cyanurate, various maleimides and various anhydrides. The particular elastomeric composition are evaluated to enhance the adhesion of the sidewall to the tire carcass stock.
