Abstract
A wheel for a vehicle (e.g., a construction vehicle, an all-terrain vehicle, or other off-road vehicle) or other device, in which the wheel includes a non-pneumatic tire that may be designed to enhance its use and performance, including to be able to be used longer and/or in more challenging conditions, such as by being more resistant to cracking or other damage which could lead to premature failure (e.g., due to manufacturing artifacts and/or rocks and other hazards that can cut, chip, or tear during use). The non-pneumatic tire includes an annular beam configured to deflect at a contact patch of the non-pneumatic tire and an annular support extending radially inwardly from the annular beam and configured to support loading by tension. An elastomeric material of at least one of the annular beam and the annular support may have selected properties, including greater crack propagation resistance when subject to tensile stress.
