FIELD: transport.
SUBSTANCE: invention relates to automotive industry, in particular to design of composite car wheels. Proposed spare wheel consists of folding disk and elastic polyurethane tire with flexible deformable spokes, said tire being assembled from segments and secured to said disk. Note here that wheel folding disk consists of two pin-pivoted parts representing semi-circle with holes for attachment to wheel hub and holes for attachment of tire segments by bolts or studs, while segments of elastic polyurethane tire with flexible deformable spokes represent metal rims whereto polyurethane material is chemically attached and which have radial slot to mounting on wheel disk, as well as holes and sleeves for attachment by bolts or studs.
EFFECT: reduced weight and size of spare wheel, increased net volume of luggage compartment.
