AI Technical Summary
Technical Problem
Conventional tires and airless tires fail to meet the mechanical requirements for extreme temperature variations and high loads in extraterrestrial environments, leading to structural issues like spoke overlap and increased stress.
Method used
An airless tire design with a rim featuring corrugated patterns to increase spoke density without overlap, combined with high-performance thermoplastic materials for the load-bearing structure, shear strip, and tread, ensuring mechanical integrity across temperature gradients.
Benefits of technology
The design supports loads between 5 daN and 200 daN while maintaining structural integrity and endurance in temperature ranges from -243°C to +130°C, suitable for extraterrestrial and terrestrial use on various soils.

Abstract
The present invention relates to a vehicle assembly (10) comprising a rim (100) and an airless tire (1) mounted on said rim (100). The airless tire (1) comprises, radially from the inside out, a load-bearing structure (2) integral with an outer surface (101) of the rim (100), a shear strip (3) integral with the load-bearing structure (2), and a tread (4) integral with the shear strip (3). The outer surface (101) of the rim (100) comprises a plurality of successive patterns (102) distributed circumferentially around the perimeter of the outer surface (101) of the rim (100).
