Abstract

The present disclosure is directed to a non-pneumatic tire assembly having a sidewall portion made from a copolyether-ester. The non-pneumatic tire assembly comprises complementary annular inboard and outboard tire casing segments. Each segment comprises: a closed end and an open end, a peripheral band comprising exterior and interior surfaces, and an inner band comprising exterior and interior surfaces, the inner band being coaxially spaced radially inward from the interior surface of the peripheral band, wherein the closed end comprises a resilient and contiguous sidewall extending radially between the interior surface of the peripheral band and the exterior surface of the inner band, the sidewall comprising convex or concave exterior and interior surfaces, wherein the open end comprises a void defined by the interior surfaces of the peripheral band, the exterior surface of the inner band, and the sidewall; wherein the inner band interior surfaces of the inboard and outboard tire casing segments are configured to be disposed on an exterior rim surface of a wheel such that the open ends of each segment do not form a sealed void within the inboard and outboard segments; and wherein the annular inboard and outboard tire casing segments are each made from a composition comprising a copolyether-ester. The present disclosure is also directed to a wheel and non-pneumatic tire assembly.
