Two car wheels - Dunlop CR 65 tires with 15 inch Borrani rims.. Each version has a 6.00 L 15 and a 7.00 L 15 version tire.The Dunlop CR 65 tires were a racing standard in the '60s, and racing cars from that era still use them.
3D printable Solidworks, STEP and STL files included containing only the two detailed wheels, with 3 pieces each (tire, rim and spinner) and some SVG files with bumpmaps for the tire sidewalls and spinners if you want to use them for displacement (3D texture). Real-world scale, so make sure to rescale before printing.
v2 update: Increased thickness on the rims spokes for smaller scale printing
Note: They fit perfectly to the 250 GTO 3d printable chassis frame product here: https://www.cgtrader.com/3d-print-models/miniatures/vehicles/chassis-frame-ferrari-250-gto-935f462b-a99b-4a24-a2cc-488caf7fd27a
