IMO, the problem with 17"-18" etc is the short sidewall... intended for better cornering/steering/handling response. Cars with monster BB engines -- especially a heavy Hemi -- need more sidewall to carry the weight, as well as through the corners. Short sidewall tires are not forgiving to the weight demands of a front-end heavy BB car.
You could consider a 16" and run 255-50-16 tires an minimum 8" rims.
The 17x8 or 17x9 YearOne replica Mopar rims do look pretty good. You could run 275-40-17 up front (preferably on the 9" rim), as well as a 305 or 315 on the rear ( a little pinched but will fir.. I've seen it). the YearOne rims have the correct backspacing to fit front and rear... I suggest staying with their 9" rims front and rear.
As everyone knows, the choices of 15" are so limited. I run BFG T/A 255-60-15 front, 275-60-15 rear, both on 15x8 vintage minilite road race rims... these are my cruising tires... rides/handles just fine.
I also run BFG Comp 255-50-16 on vintage minilite road race rims, 16x8 front and rear... for track lapping events... handles fine.
Eventually, I'll be getting 18x10 (or 10.5-11 wide) rims and run 275-35-18 200 compound tires for track events.
Unless you're running track events, the choices of 15" tires are OK for cruising... even at 245-60-15 fronts as the smallest you'd want to go.
