Corgi Toys 275 Rover 2000 Golden Jacks Set of 4 Wheels.
This model did come with a 5th wheel in the boot mounted holder.
If you need the 5th wheel please look for the single wheel option.
The wheel hubs are a white metal casting and are not a machined finished.
You may need to adjust the hubs by removing any excess casting metal and bring them into 'round' for rolling correctly.
For static display they should be fine.
