Abstract: A non-pneumatic tire having a plurality of individual modules is mounted on a wheel having with a plurality of depressed module mounting slots to form a wheel and tire assembly. Each module has a body with an opening in the middle that separates the upper region from the lower region. The lower region has an attachment hole for attaching the module to the mounting slot. The lower region of the module and the mounting slot are shaped accordingly to fit each other. The module has two arms, each having an interlocking face disposed at their ends. A full set of interconnected modules forms a complete annular tire. The wheel includes a plurality of depressed mounting slots with a wheel attachment hole disposed around the rim where the modules can be mounted. The rim includes flanges that bound the mounting slot on both sides preventing the modules from sliding sideways.
