Found 15x10s with a 6in back spacing. They are a good price. Really don't want to go through the trouble of mini tubing. I mean I will if I have to. Anyone have a 67-69 barracuda with 15x10s ? I like the look of the wheel & tire tucked under the wheel well.
15x10 WHEELS ON A BARRACUDA
- Thread starter cawley

Dusters and Demons have a similar sized wheel tub as the Barracuda. I run 18x10’s on my Duster with 295’s, no mini tub. I have a 1/2” spring offset and about a 1/2” taken off the quarter lip.
With a 6” backspace and an A body 8 3/4 even if you’ve got BBP axles you’ll need a 1/2” spring offset at least a spacer on top of that. BBP axles and stock spring locations usually give you about 6” from the wheel mounting surface to the spring on an A-body, so that wouldn’t be any room for the tire overhang or clearance. The 1/2” spring offset would give you clearance but not any more for tire overhang, so if you went 275’s or more you’d need a spacer to account for the sidewall bulge.
Basically that’s too much backspace with an A-body 8 3/4 and BBP axles unless you have a 3” relocation and mini-tub. It’s not the 15x10’s that are the issue, just the backspace for the axle. My 18x10’s are a 7” backspace, but my B-body rear axle is more than an inch wider per side.
Barracuda's bodies at the edge of the quarters are a little narrower then the Duster's.
ok change of plans couldn't get ahold of the 15x10s so Im buying 4 17x7s & I will sell two of them. Then buy 17x8s or 17x9s for the rear. What for front tire size do you guys think I should run on the front & rear ?
So why do they use the same AMD inner and outer wheel houses then? Duster has wider lip on the wheel opening on the quarter, but that doesn't make a lick of difference for clearing the tire if it's inside the wheel house.
AJ/FormS's Barracuda measures within a 1/4" of my Duster inner to outer wheel house, that's factory tolerances.
What is the backspace on the 17x7's? What are you running in the back for a rear axle? 8 3/4 with BBP axles? Stock spring locations? Makes a pretty big difference.
In the front with a 17x7" a 215/50/17 would be your best bet, it's 25.5" tall. About the widest you'll be able to do is a 225/45/17, but that will still depend on the backspacing and that's only a 25" tall tire. Maybe a 225/50/17, but with the Barracuda front wheel opening you have to modify the lower front corner of the fender when you get close to 26" tall on the tire. 235/45/17's are supposed to be mounted on 7.5" wide rims or better.
What are your plans for the car? What tires do you want to run?
Ive used the nitto brand street slicks before & I like them. 17x7- 4 in back spacing 17x9.5 I want to run on rear have a 5.05 back spacing. Ill do what I have to do to get the rears to fit in the wheel well. I don't want to run a wide tire on the front.
Ok, so with only a 4” backspace on the 17x7’s don’t go any bigger than 215/50/17’s up front. Those should work though.
In the back, if you want to run 17x9.5’s there’s no reason to do a 3” relocation or mini-tub, you can’t run a wide enough tire on that rim to make it worthwhile. You really don’t even need to do the 1/2” spring offset as a 275 is really about the widest you’ll be able to go, and with a 5” backspace and BBP axles a 275 should already fit.
I looked into the Nitto’s, they have a 275/40/17 in their drag radials but that isn’t a ton of sidewall, that’s a 25.6” tire. They have a 555 G2 in 275/50/17, which would be great as that’s 27.8” tall. But that’s a handling tire for modern cars, not really designed as a drag tire. There is an M&H racemaster drag radial in a 275/50/17 if you want to do that instead of a Nitto.
Honestly for what you’re describing, narrow tires up front, “street slicks”, not low profile tires you may be better staying with 15’s. I know I don’t say that much, but it really depends on use.

I just read these posts , I have a pair of 15x10 prostars, I had one of my 295 60 d15 tires mounted on one , and it was right underneath the out side of the fender, would have worked with a 50 series tire. If they were 3 1/2'' back space instead of a 3'' , it would have
THESE DONT HIT AND ARE ACTUALLY UNDER THE CAR/8'' RIM THO.
I really want 17x 10s but they don't make them I just don't want a wide tire up front & id like to have the rear wheel well filled up.

Nice! Do you have a picture with the 15x10s ?
Your wrong , I just measured two cars on rotisseries that are here . Dusters are 1 1/2 inches wider, 3/4 per side then barracudas. with factory quarters . I recently had wheels made at wheels vintique 4 1/4 backspace they just fit under the barracuda . The 4 inch were tight on the barracuda. the 4 1/4 gave just enough clearance.
From the inner wheel house to the outside of the quarter barracudas are 13 1/4 Duster's are 14.

I think------------on my phone and cant get them to up load to this piece of crap. Send me ur phone number , I`ll send them to u . sorry--
when it came to the barracuda was there any thing done to it springs moved inner wheel house moved in ?
I love that after all these years you still think those tires are "under the car". Lower that car 2" and the body would be sitting on the tires. Those tires would not clear the quarters at a lower ride height.
As long as you find the tires first I see no problem with that plan. But there's only a couple of options for tires in that size, so make sure you want to run of those tires.
Actually you proved me right. You just ignored what I said about taking the measurement. The body is wider because of the flare/lip on the quarter, it's just a styling detail and has no impact at all on tire clearance, which is exactly what I said earlier. The outer wheelhouse is exactly the same part. If the outside lip on the quarter made any difference for tire clearance, you'd have a point. But what you actually need to measure for tire clearance is the distance to the outer wheelhouse, not the outside of the quarter.
Let's put it in pictures so you understand, since I also have a Duster sitting in my driveway.
The measurement to the outside of the quarter lip is 14-1/8" on my Duster. But, that's a meaningless measurement unless you remove the outer wheelhouse. The measurement that's important, the measurement to the inside of the outer wheelhouse is 13-3/8" and 13-1/4" on my car. That's after the quarter lip was cut back to match the outer wheelhouse. That's the tire clearance measurement you need. And that measurement is the same on Barracudas and Dusters. With factory body tolerances, you should expect to see that measurement to be around 13", give or take a 1/4", with a car that has stock quarter lips.
AJ/FormS's Barracuda measures 13.25" to his rolled quarter lip, my Duster is 13-1/4" on one side and 13-3/8" on the other. It's the same.
His measurements are here 275's on a dart sport
The only difference is the outside styling on the quarter, there's an extra raised lip on the Duster where the Barracuda actually has a little bit of an indent on the body detail. But neither matter, because the distance to the outer wheelhouse is what's important for tire clearance. And the outer wheelhouse is literally the same exact part on both bodystyles.
Those would be for stock locations. Actually they're probably for SBP axles too, because with BBP axles most cars have about 6" from the wheel mounting surface to the stock spring location. Subtract a 1/2" for tire clearance, another 1/2" for tire overhang/sidewall bulge and you can run about 5" of backspace on an A-body with an 8 3/4 and BBP axles. With a 15x8" and 275's a little less backspace usually works better because of the sidewall bulge, which is why 15x8's with 4.5" of backspace is usually the ticket for BBP axles. With 17x9.5's and 275/50/17's there would be almost no sidewall bulge because of the tread width matching the outer lip of the rim, so you can probably even run a little more backspace than 5".
Both cars are factory and they are different to the wheel house lip also. 3/4 difference from duster to fastback. Cars are both here .
Well let's see the pictures then shall we? Because the AMD replacement panels are identical for the inner and outer wheelhouses. Same part #, same part. All the '67-69 Barracuda's, all the Demons and Dart Sports, all the Dusters.
I replicated your 14" measurement, the raised lip on the outside of the quarter doesn't change a thing for the tire clearance. The lip on the wheel house is what matters, so let's see that measurement. The frame rails are in the same place, so, if the inner and outer wheelhouses are the same part (and they are), then you're not going to get a measurement that's different by more than body tolerances.
Maybe @AJ/FormS has a picture of the measurement on his car, since I already made reference to his 13.25" distance from inner to outer wheelhouse, which is the same as on my Duster.

Didn`t read all ur post, ''not that interested'' . By unde3r the car I meant "not sticking out past the body lines'' . The springs are standard mono leaf caltracs , not really jacked up
tires sticking out past the fenders are what looks bad to me ----------.
By the way , dont tell me what is on my car , or how u think its built , u dont know **** about it / mine !

He knew what you meant. He was just being an opinionated ***.
When you are trying to fit tires on without modifying the shape of the quarter you can fit a lot bigger tire on a Duster under the car. Trimming and rolling to the outer quarter lip still gives you 1 1/2 inches more total width on a Duster/Demon to keep them under the car. The bottom line is the barracudas are 1 1/2 inches narrower as I stated. That is a lot more room to work with. 3/4 per side.
Looks like you trimmed most of the outer wheel house off on the pictures of the Duster above. You won't do that on a Barracuda and still keep that much of the lip on the quarter
I made no assumptions about your car. The ride height is clearly visible, it’s higher than stock. And that’s fine, it’s your car.
The only thing I said was that the tires are not “under the car”. If you want to split hairs and say they don’t stick out past the quarters that’s fine. But at a stock ride height those tires would rub. Plain and simple.
I didn’t tell you to lower you car, say it looked bad or comment on anything beyond the fact that those tires would not fit inside the wheel houses. And they won’t, that’s obvious from that picture. Even having the tires even with the outside of the quarters means they won’t fit inside the wheel house, you’ve still got the quarter lip and outer wheelhouse to deal with.
By saying those tires won’t fit in the wheelhouse? They won’t! I said nothing about how it looked or anything else.
On my car I trimmed the quarter lip back until it was even with the edge of the outer wheel house, yes. On the drivers side I got into the wheelhouse a couple times because there was less lip than on the passenger side that I did first so I was a little aggressive with the cut. But the outer wheel house is basically unchanged as far as tire clearance goes.
The last 3/4” of that 14” measurement on the Duster isn’t anything you can put tire in. To put it simply, my Duster is cut back as far as you can go without removing the outer wheelhouse, which gets you about 13.25” from inner wheelhouse to outer wheelhouse.
This is the problem, just look at the wheelhouse from inside the quarter. It doesn't matter that the outside body measurement on the Duster is wider, the wheelhouse is the same. That extra space is just that, extra space you can't put a tire in unless you start moving metal.

I didnt bother to read all ur posts this time either
You must be forgetting ALL ur past posts --------nuff said
Ride height is 1 inch lower then factory. front is almost on stops and rear is in the top holes with mono leafs. Here is a picture of the same car with 275 60 15 on 8 inch wheels. then with The bigger 29s with front runners that made the car look lifted in the second two pictures. They are 29 14.5 on 12 inch wheels

^^^^^^^^^^^^^^^^nice car .
Any one know or have the heigth of the center of the rear fender wells on a 68 fastback?
Curious , I dont think the heigth of mine is jacked up , other than having 29'' tall tires on it either !
