geez, lotta info. I def want some meaty tires, but unfortunately also want a bigger wheel. I hate the look of a car with like 17 or 18 with super thin tires, they always look out of place. I guess I need to find the balance. My thought was an 18 in rear, 17 in front. Have a meatier tire in rear and less so in the front. ???????????
Unfortunately, to most of us here, anything over 15 inch looks "donk". I am going plus one to 15" wheels, but anything above that and you lose too much sidewall IMO.
I haven't seen 18s on an A-body. The 8 inch width and 4.5" backspace are crowding the limits of what I have seen people do with 15 inch wheels. I have seen some 17s running a 50 series tire that I thought looked OK. IMO that's as far as I would care to go. Cragar makes an old-school looking wheel sort of like the Boss 338 in a 17 inch size. Check this out 17 x 7 and see if it makes the cut.
