Has anyone run this or a similar setup? I'm curious if 19" wheels will allow for 5.5" backspacing. Was going to try for 345/30r19's but those are too hard to find. Found a killer deal on Bridgestone 275/35r18 and 325/30r19 tires, so now I'm really trying to nail down the right backspace.
Major manufactures don't make wheels that have strength issues because of liability. The max strength is past half way outboard or a lower positive offset inches. I use studded wheel adapters. 13 inch wheel with a 7 inch BS and a 2 inch adapter is a good example. It is equivalent to a 5 inch BS wheel.
the offset from centerline is good for caliper clearance.

Where did you get this information? Everything I’ve read points to the physics of adapters being the absolute last resort due to integrity and increased leverage on the axles. I don’t see anything to support this negative offset theory.

Just call Centerline or Weld wheels and ask what BS are available and why big positive offset is a bad thing.
the farther out the curb side of the tire is..... the higher leverage and loading on the outer wheel bearing. Not a big deal if your wheel bearing only last 1/2 as long, because when was the last time you had one go bad? What is happening with a same width wheel and exactly the same effective Back Spacing only using a wheel adapter? The loading is the same! So this is an untrue statement: "Everything I’ve read points to the physics of adapters being the absolute last resort due to integrity and increased leverage on the axles."
It was in the 90's when I first installed 2 inch wheel adapters. Other than the 5 wheel studs they have a big flat face of metal to metal for a mechanical bond.
Do you have a picture of the side? I’d like to see the stance and how they sit.

Actually, I don't think I do. All my pics are with 17x11 rears. I'll try to get a pic within the next week or so, car is on trailer and 18's are sitting off to the side right now.
My 335 rear tires on 13 inch wheels and 520# custom mono spring from VB&P.
George,,,, which offsets are you running? The standard 2" or the double offset TA @4"? What mods did you have to make in the wheel-well? Did your rear sway bar work or did you have to get a new shorter one? I know you have flares, but would the tires fit without flares?
Here’s a pic of my 68 with the L88 flares. Those are 18x11 on 295-40-18. I’ll be adding 1.5” adapters on the back and 1” on the front.
Thats great! Thank you. What brand wheels are those? I’m looking everywhere and haven’t found anything I like cheaper than $2700 for a set. I can’t see all of yours, but the reflection on the wheel makes me think I would.

They are 18x11 American racing vn327 with 4” backspace. I paid $1800 for them. Ron’s rims is the seller if you’re interested in a set. Here’s a side shot. The centre caps are missing though.

I only have HD trailing arms with Tom's outers. Years ago I bought offst trailing arms and right away I saw that the problem would always be the upper frame rail rail kick up as the limiting factor for back spacing of the wheel. Then of course the spring ends and the sway bar. So I have 13 inch width wheels with 7 inch BS and 2 inch adapters which gives me a net BS of 5 inches.
So I have a spring end 3/4 inch VB&P sway bar that I modded to bring the ends in for a more perfect vertical attachment.

Ok,, your solution then was basically wheel well flares... Im trying to fit the biggest tire in there with out a flair kit... i think its 295's..

19x12 rear wheels 325/30r19 with L-88 Flares?
