I need to get some wheels..have been debating torque thrust D...what do you mean rough? Are they 18s or something?
 
Cragars are chrome and require the same if not more upkeep since the chrome likes to pit,rust and peel off of the cast aluminum in time.

You need to check the backspacing for your car and the wheels

You running 4.5" BC?

Should work fine on the BS but I would personally do 6" up front.

I agree with both of the above. 15x7s will most likely fit with the right BS but I think even with that being said, it might be a tad bit easer to work with the 6s. GL.

Totally agree!
Back in the '80s there were several Cragar copies, most were all-steel, guess what? They didn't corrode!
I'd never buy a set of these wheels.
 
What brakes are you running up front, and what rear axle do you have out back?

If you're running the 73+ BBP disks up front the 225's in the front will be pretty tight. I ran 225/60/15's on my Duster for awhile on 15x7's, but the backspace was 4.25" and they were very close to rubbing. You might consider 215's if you don't want to do any trimming, rolling or ride height tweaking.

In the back the 15x8's with a 4.25" backspace and 255's should work, which rear axle you have will determine how close they are on the quarters.
 
Just going through this on my Barracuda. I need 4" backspace on my LBP 8 1/4 with 8" wheels to do 255-60-15. Having a set built by the mopar dude.

Which is why I asked which rear axle he has. The BBP 8.25 is narrower than an A body 8 3/4" with BBP axles. On a duster a 4" backspace with 15x8's and a BBP 8 3/4 would put you into the quarters with 255's.

Was there a reason for only running 4" of backspace on your barracuda? I know they have plenty of room out to the quarter, but those measurements should leave quite a bit of extra space on the spring side with 255's.
 
Running the sbp 8 3/4 and running lbp 15x7 rallye wheels with a 1" adapter and i can fit 275/60R15's on tve back with anout 1/2" of clearance to the springs and maybe s 1/4" to the quarter lip

The reason I choose 4" BS is because after drawing everything to scale on my CAD program, it was the best overall fit. No spacers for me. The CAD showed 4.25" would work but it was pretty tight. Just being cautious. May try 275's just for grins.
 
MoparJ, here's a old pic of one of my cars with 15x8 Cragars with 4-1/4 back space and 255/60R15 tires. 8-3/4 axle also.

Huh. I had 275/40/17's on 17x9's with a 4.75" backspace fit on the BBP 7.25 in my Duster back when everything was stock. Those were pretty tight on the springs, they might have needed a little more spacer for street use. But only an 1/8" or so. That's a big difference from 4" still.

Those seem to stick out further than the math indicates for those specs. You couldn't lower that car and still have those clear. Any chance those cragars have a 3.75" backspace? A lot of the older ones did.
 
Don't know, I have bought everything for my car three times including wheels. I want 15" Mopar Rally's with centers and rings and that's what I have after three tries. My research for my car shows that 8" X 15" X LBP wheels with 4" BS will be optimal for me, that being said 4.25 might work. I have had cars that I have torn up the sidewalls on by putting the wrong tire/wheel combo on. I like to think I have a little more wisdom now. (although there are several who would question that) In any case, when I get my wheels I will have them powdercoated to match the existing 4.25" BS 6" wheels for the front and put the biggest tire on the car that won't rub the springs or wheel wells on the back. Will post photos when the time comes.
Cheers to all, I have decided to work 3 or 4 days the rest of the month and Jan 2, 2017 I officially go to 3 days a week/on call semi retirement and I am in a pretty good mood these days. Less work, more time for the Rat:) Stay warm all and don't get snowbound or frostbit!
:popcorn::lol::thankyou::)
 
72blu, my Cragars are 4-1/4 backspacing but forgot to mention I have air shocks on so it is sitting higher in the picture.

Yes, but the BBP 7.25 and 8.25 are the same. All the dimensions are in the 8 3/4 width list that's stickied in the drivetrain forum.

Interesting. I'll have to check my math, because those would not fit on a lowered car.
 
Yeah those might not work for a lowered car unless you cut that inner lip out maybe.

Yeah that would be my guess just by looking at it. Of course the angle of the picture and all of that make a difference in how it looks. A BBP 7.25 or 8.25 is ~56 3/4" drum to drum, the A-body 8 3/4 with BBP axles is ~57 13/16", so the difference is just over a 1/2" per side. By the math that makes it really close on the quarter side, but that picture looks like it's a bit beyond close. Which is a good reminder why everyone should measure their own car before laying out the cash for something.

I had Cragars on my original '69 Dart for a lot of years without any issues with the chrome. Upkeep was very easy following a wash or wash'n'wax.
Over the years I've found the upkeep on the Cragars much easier than on all-aluminum unplated wheels.
