Just, no to you. You obviously have no clue what hes talking about.
Hes asking if you can have a vehicle tire appear in the items menu so you can spawn it as a prop. It doesn't matter how vehicles work, its not changing how they work at all.
And if you think it's a good idea, why would you hide the somewhat productive part of your post and even post at all?
