I want to make a formula one car at least 30 cm in length out of standard LEGO parts. None of the LEGO wheels I have are big enough for this scale. Where can I get some big wheels that would look ok? The big tires here are too big. I looked on BrickLink, but just got confused.
You may want to have a look at some official LEGO sets of that scal to check what LEGO has been using.
You can also look in the specific section for wheels on BrickLink for other sizes.
