Unsolved car loading without wheels

hello, I am making a private meshslap of the kerr, it's supposed to be a camaro but it is loading without wheels and I don't know anything in the console

 

I haven't done this myself so far but if I'm correct the files from the wheels go into /vehicles/common/wheels. (?)
Just a first thought on the matter.. maybe extract a copy of the 'common' folder into a wip map and
see what's going on in there.

 

My car doesn't have common. It is a kerr

 

Not sure but then maybe that's the problem. What if you try to put the wheels / tires files into 'common' ?
