My 1971 Duster 6.1 Hemi build

I'm in the same boat as you. I bought 13" Baers for the front and I believe (have to double check) 13" for the rear. My goal is 28" tall tires in the rear and with 18" wheels, would allow for a 5" sidewall. I'm good with that. However, if I have to use an 18" in the front, my front sidewalls are going to be at least an inch shorter (want about a 26" tall tire in the front). With a Duster, I believe your fenderwell radii are about the same as my 69 Cuda (fairly big compared to a Dart).

I'm going to invest in a measurement tool of some sort so I can get maximum width, correct backspace, offset, etc to fit my car. I'm not real concerned if I can't get as wide of tire as I would like for the street, as when I race the car, I'll put full on wrinkle wall slicks on it. Your biggest problem will be finding that perfect size wheel / tire combo that lets you do all that you want to do. You may have to go with 2-3 sets of wheels/ tires! lol Not sure what I'm laughing at, I've considered having 2 sets myself!

Enjoying your build thread. Keep the pics coming!
