FIELD: transport.
SUBSTANCE: invention relates to automotive industry, particularly, to wheels that allow motion at no excess pressure in tires. Proposed internal support is rigidly secured to knock-down rim by thread joint inside air tire. Support is splitted into teeth that feature elasticity that allows bending by magnitude in contact with road surface equal to difference between support circle arc lengths and those of tire iner part located in contact area.
EFFECT: higher stability at pressure drop.
