In a future update it would be awesome to be able to change each individual wheel on a car. Example: change only rear left or front right. If a tire pops and you want to imagine that you put on a spare.
I agree. Something that would allow for cars to look even in a worse state is to have 4 wheels 1 or 2 of them different from the other and not just have 1 or 2 pairs. The dev team has been proved to be able to pick parts and dismantle them into smaller parts already. This is a very likely easy thing to do.
