Design of a wheel, brake, and tire capable of operating from an ambient temperature of 800°F appears feasible. However, there are many areas which necessitate intensified study. Most prominent are mechanical tire approaches, bearings and lubricants, and hydraulic or pneumatic dynamic seals.nThe mechanical tire, and tread material, is the most revolutionary and challenging region to be conquered. Various mechanical tire approaches were herein considered. Designs utilizing spring configurations were more acutely investigated. Initial studies indicate that a mechanical tire possessing a spring configuration will involve a considerable weight penalty in comparison to the conventional wheel and casing presently being used for low temperature applications.
