if you come to think about it - if you put in tyres, they would be still very thin. just thick enough to be allowed. i love the air vent - even though right now you can look too far in. i know it is wip, but i suggest you make it like an L going in - so it is not possible to see the inside from any angle. this way you dont have to worry that the inside needs modeling.
keep it up
