摘要 |
A molded tire may include a support structure having an inner circumferential portion and an outer circumferential portion. The inner circumferential portion may be configured to be associated with a hub. The molded tire may also include a tread portion associated with the outer circumferential portion of the support structure, wherein the tread portion may be formed from a first polyurethane having first material characteristics. The support structure may be formed from a second polyurethane having second material characteristics different than the first material characteristics. The support structure may be chemically bonded to the tread portion. |
