Headers question

Bobzilla said
What size front tire and wheel are you guys running with these Headman headers? Backspace and width of front wheel if known as well please?

I think mine are 15 X 3 1/2" with a 1 3/4" BS, the tires are 26" tall M/T radials. On my Dart the tire will hit the fender before it even gets close to the header.
