It was good thinking to include a spare tire, but the effectiveness of that choice is mired by the fact that you have what looks like 3 different tire sizes on the actual vehicle. This means that you either need to carry three spares or just hope that if you blow a tire it's the same size as your single spare. Another thing to consider is that if the vehicle has four wheel drive, different sized wheels would create a drivetrain catastrophe (different diameter wheels rolling at the same speed will revolve at different RPMs) that no engineer would ever want to fix just because differently sized tires look interesting.
oh damn i didn't think of that haha. i'm really glad u spent time to think through my design. i guess sometimes i don't think about the engineering too much and i focus a lot on the aesthetics or just fooling people into believing stuff in games/movies.
but yeah i do get what u mean. that added sense of realism would add to my design cheers mate!
but i like it
Do Tweak your design to make it more realistic
