I tried a few different 17 inch tire combos and came to the conclusion that 235/55-17 is almost perfect for muscle cars. That size is tall enough to fill up the wheel wheels, it has a good combination of ride and handling and it is an easy size to find.

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. I don't think you're wrong on anything you've said here but I'd like to offer a couple of (hopefully helpful) counter points. 1) as for big block cars needing the extra sidewall...I get your point but the question comes down to the goals of the driver. Sidewall flex isn't always the preferred way to manage suspension compliance, especially in cornering as any sidewall deflection will come at the cost of contact patch. Yeah, the extra sidewall usually gives a more comfortable ride but it's very seldom going to help any car get through corners. Before buying tires/wheels, we need to check the load rating...then tune the rest of the suspension to taste. 2) I'd say NO to 16" wheels...they're a good compromise for looks and more modern sizes but they're also pretty un-loved in the performance car world. They were probably "in style" for an even shorter amount of time so market support for 16" wheels may not be as good as 15" just a few years from now. 3)YearOne replica Mopar rims- ehh...100% personal taste but they do not look great to me. I really wanted to like them but after seeing them in person, they were just "ok" IMO if you squint. Lots of folks do like them but I'd strongly urge the OP to see them in person before buying. As for your choice of 15" Minilites on the 'Cuda... flawless taste, sir. If I had the money, that's exactly the route I'd go.

Those are the unreasonably priced tires I mentioned above. $400 each in the size you mention.

I don't know, some random tire I picked up at the local tire store. That is the nice thing about the 235/55-17 tire size. They are so common that you can get a speed rated tire for discount prices.

I don't know anyone in the US of A who is running these but they look AMAZING. Vintage style, sticky compound, street legal tires...slightly limited in sizes but they do offer some 60 series choices that could work (245/60/15)...yeah, 80 treadwear rating...but still http://www.avonmotorsport.com/historic/historic/cr6zz Those are the unreasonably priced tires I mentioned above. $400 each in the size you mention. That is because these are the Z rated racing tires that just happen to have a d.o.t. rating that I mentioned earlier. They are popular for the kit Cobra crowd for period correct look and ultimate grip. You can find them state side at Roger Kraus Enterprises on the west coast or Frisby Preformance Tire in the mid west.

The wheels are a different issue. Those are custom built Fikse rims. They cost a small fortune.... While that’s a bit disappointing, I’m glad that it looks like you got what you paid for. They’re probably the best looking 17” wheels I’ve ever seen on a Mopar! At least it will be extremely unlikely that anyone will be able to copy you.

Fikse strong, light and a work of art. you see them on high dollar cars. $1200 to $2000 each, do I need to say more but I want a set.

Just been busy enough to read not reply . The Hemi challenger isn’t mine it a project I have been working on for a few years . Things change in the original build but one thing I bought early on were 4 no’s 15x7 ralley wheels and although we upgraded the brakes to larger frt and rear disk they fit the 15 Ralleys .
I don’t care so much about white letters but the car owner has some strange ideas about top speed runs .... I just want the car to somewhat safe at speed . It has dynoed at 750 hp and is an all aluminum fho hemi 727 with a gear vendors and 3:23 gears it is still a 70 challenger but the real top end will be limited to the driver . If it was my car I’d go to the 17” ralleys

If it was my car I’d go to the 17” ralleys In triple digits speeds these things get to be a handful for any sustained amount time. A 150 blast down a strip is for a few seconds at top speed is entirely different than 120 for 5 minutes. I would think that H rated tires may be fine. SAE speed rating tests the tire at the target speed for an hour at 100*. That's more than I'd imagine the driver, and the car, would be up to. Maxxis, MT SR, and Hoosier Pro Street can do this. If skinnier tires are okay, the V rated ones higher up in the thread may be okay. The Avons can take him into Z rated territory. He also could look at Hoosier Circuit Racing wet tires that have a street appearing tread. However, these may not have a d.o.t. stamp which could be a problem if he has street inspections to meet. IMO, if he has sprung for a 750 hp Hemi, then $400 each for Z rated tires is chump change. Tires and brakes are consumables. He can't cheap out on them because they are.

You may have also noticed that these tires are listed as an "approved 1B permitted race" tire in the UK, which means it is the equivilent of a Hoosier d.o.t. compliant SCCA competition tire. Maybe your cherry picking your points, maybe you're just a lazy reader and stopped once you found your point, but, as you say...whatever.

Pot kettle If I was only reading enough to prove my point I would have read that is it not DOT compliant. The equivalent is not the same as having DOT compliance on the sidewall. Point I was trying to make, which I apparently didn't make to you, was that if you want to run stupid speeds with a 255/60R15ish tire this is what you have to pay and what you have to run. If you are a bit more flexible in your sizing you can get more reasonably priced tires that meets the speed rating and are genuine street tires not pseudo ones.
