Cragar SS 15x6 with 3 3/8” BS

Like the heading says, I want to install these on my 1969 Dart. I was always told 4 to 4.25 inch BS was the way to go. I found a smoking deal on a set of brand new 15 x 6 Cragar SS wheels and I want to run to 215/60/15‘s upfront and 245/60/15’
s outback. Anybody Run this tire size with a spec spacing on this vehicle? Thank you
