Unusually used parts on partstracker?

[Chris Dee]

Is this even a real part?
A part made from a third party custom manufacturer, or is it a user adapted custom file?

Hello Magnus,

It is an original part..... user adapted.

Here it is in original shape -- >https://www.bricklink.com/v2/catalog/cat...8#T=C&C=11

What do you mean by 'user adapted'? Did you cut the original part to make a narrow tyre?
