load through the axle to the tread band and then to the road in addition the sidewall portions would also provide for one or more locking mechanisms the sidewall portions of the wheel may provide a compression fit via the lateral support surface as shown in fig8 the non pneumatic tire to spider interface may use the technology revealed in this specification for the tread to web interface the support surface may incorporate a gear tooth interlocking configuration to mate with the lateral edges of the tread band portion the sidewall portions may also provide for a crenellated interface at the support surface as shown in fig8 an adhesive on the lateral and or circumferential mating surfaces could be used to maintain intimate contact between the tread band and the sidewall portions fig9 shows the interface between the wheel and the tread band interface 90 of interest is illustrated by two adjacent thick curved colored lines 92 and 94 in fig9 the creation of the specific surface of this invention will now be described the specific configuration of the mating surface would be designed to provide a shear stress that is below the limitations of the materials or adhesives at that surface the non pneumatic tire to spider interface 90 may use the technology revealed in this specification for the tread to web interface the tire with a separable tread band 96 has interface 90 between the separable tread band 96 and supporting structure 98 the shape of the interface.
