Hello. It sounds like you're having a material issue if the wheel is hidden. It should import with at least 1 wheel model, this wheel is then instanced onto the 3 other wheel dummies once it's loaded ingame.
Please let me know if this video helps you achieve the result you're looking for. Here I'm using rotation snap toggle to rotate at a fixed rate of 5 degrees, and align tool to align the extra wheels to their respective dummy. https://streamable.com/i7hyvs
