Help pls

When the wheel is spinning, the tire looks like this and this from the side.

If it's not completely clear how this happens, I can throw off the link to the video.

Sometimes I make an add-on car from replace, and when I try to spawn this car, my trainer simply collapses to spawn the car and does not unfolds (and does not work at all), why is this happening? (I have configured all .meta files correctly and do not understand what the problem is).

Crashes of the game occur randomly. Sometimes I can riding all over the map for an hour several times and nothing happens, and sometimes it happens that as soon as I drive up to that area the game crashes.

@Aurora11 my game crashing in this area:

Can anyone please help with convert cars from Forza Horizon 3/4 to GTA 5?

@Marc30499 I have these programs.

@Marc30499 if I get permission from the author for editing or I make an convert from another game, how do I make the car set up for make livery on it?

@InfiniteQuestion Is it possible to import this car into zmodeler 3 and do something there to make the car set up for a livery?

@InfiniteQuestion I know car isn't set up for a livery. But is it possible to somehow get the template and then apply the livery to this?
(sorry for my bad english)
