Is there a science as to what size slick should be used on a race car, or is it just personal pref? I am in the middle of building a 450 wheel hp race car. Shall i use 22's or 24's i dont know someone help me out if you have any hard core info.

 

I don't know what to say about the size..

but if you can, wait to buy your wheels/tires unti lthe car is really close to running. otherwise they are just going to sit there taking up space.
