show the white letters?

I like white letter tires, but it depends on a couple things; like if you're going for the "Day 2" look.
What kind of wheels they're going on; some wheels just don't look right with RWL.
What size the tire is- thin sidewall "rubber band" tires don't really show off the RWL.
What brand tire it is. Some have goofy script or logo on them that makes them look ridiculous. Those go to the inside, I don't care how good the tire actually is.
