E-Body Tire Combos

[BS CUDA]

 I just had the perches moved in 3/4" on my E body rear - offset shackles - I currently run 15 x 10 - 5.0BS but will be moving to a 5.5BS so I can sneak a 30" tall tire underneath her.

That set of wheels is what I want. And the original style fits the car.
     Does the inside of the wheel's center bore, fit the disc or rear axle,  drum hub like a stock one?
     Also, will solid valve stems clear the rims inside edge?

The valve stems have to be pulled through due to the recess. They fit the hub like a stock wheel perfect.
     One wheel was damaged in shipping so I'm waiting now. I bought the 225/50 R17" Goodrich Comp W rated for the front. It clears the front edge of the well by 3/4". I suppose a 235/50 would have fit too. I wanted the tire to be trim and not have any side waddle that comes from a wider or taller tread. Or any of the other suggested sizes. I want to make city turns, quickly and easy to maneuver.
      The tire's actual size is less than posted. The 9" tread width, is edge to wrap around edge. It only has 7.80" on the ground with full car weight. The height is 25.35", not the 25.80" advertised. So that's why a larger, 4 same size tire approach would be better for those with power steering. My wheel's weight @ mounted is 53 lbs. Wheel's 21 lbs. A bigger tire adds another 5 lbs each.
      My front fender top is even to the top of the tire and they sit far in, like stock looking. I have 10x29" slicks on 8" Welds out back for now. Dr D kit 68 housing Moser axles, MW spool 5.13. It fits with a 7/16 spacer and over 1" to the leaf and well top, it has 1 3/4" room to the front opening for growth and side waddle.

ARACER -- I suggest you get the Year One 9" rims front AND rear.. 275-40-17 tires front and rear... you can then rotate them front-rear... no problems with that setup on ANY E-body.

Mitch, is it for sure that the YearOne 17x9 Rallye-rims with 275/40-17 rubbers clear out on all 4 corners with no issues / no mod`s needed on a 70 Chally R/T with stock front/rear-suspension?

Thanks for your advice!

Se 72bluNblu comment... July 16, 2016:

"...I run 275/40/17's on the front of my Challenger with 17x9's and a 5" backspace. They're a little shorter at 25.7", and require a 9" wide rim..."

Since the Year One rims are CORRECTLY offset, at both 8" and 9" widths, there's no reason why a 275-40-17 tire mounted on a 17x9 rim with the correct offset/backspaing shouldn't work.  The tire is relatively small in its diameter.

My car is lowered f/r using 16x10 rims with zero offset (5"backspacing), which pushes the tire/rim outwards ~1/2 inch from the preferred correct positioning.... using 275-45-16 Hoosier A6 DOT Autocross tires... flushed the lips, pulled out a little, appears stock... IF the rim's offset was correct at 5.5 ", then I'd probably NOT have had to make those mods (again, car s lowered for autocross competition).

I suggest you re-confirm with our comrad 72bluNblu here as he has a Challenger and ruins 17x9 275-40-17 both front and rear.... I'd run them easily on my car, even without any lowering or slight fender mods... I'd be 100% certain they'd fit A-OK.

My ears were burning! 

Yes, 275/40/17's on 17x9's with a 5" backspace should clear on all 4 corners. My car sits pretty low, so, I have removed the brace that runs from the inside of the fender to the top of the wheel arch on the inside of the fender. That's a ride height thing though. At the stock ride height that probably won't be an issue. I run with my headers about 3.75" off the ground and the top of the wheel opening at a smidge under 25". That brace can be removed even on a finished, painted car without disturbing anything if done carefully and can't be seen from the outside. And it may not be necessary, just depends how low you are.

Usual caveat applies, the body tolerances on these cars are not exactly precise and every car is a little different. A 275/40/17 fills up almost all of the available space, so, it's not a guaranteed slam dunk, but it should work.

Thanks so very much for confirmation, Mitch an bluNblu!!! 

Of course I am aware you cannot guarantee for nothin.

Also, I'm pretty sure that Year One actually advertised 275-40-17 tires on their 9" wide rims for BOTH front and rear onto an AAR Cuda... and I tend to favor the Challenger has slightly larger wheel well clearances (your measurements may differ).

I think I have heard that the Challenger has wider REAR wheel openings while the Cuda has wider FRONT wheel openings. I would like to know the true answer to this though.

It could be but I don't know for sure. I know cudazappa was running 275/40/17's on 17x9's with a 5" backspace all the way around on his 'cuda, as I based the sizing for my challenger on his. I don't think the front is that different. Based on some of the rear tire sizes I've seen, the challenger's may have a little more room in the back, but I don't have measurements to prove it.

Back in the day, I had a Cuda and a Challenger. 295-50-15 fit on the Cuda and would rub once in a while, and on the Challenger it was unusable even with the assistance of air shocks.

I'm confused? I thought you already have these wheels? 

[Cudaragtop]

Just wanted to share the best price for these I have ever seen.
They are for our 69 Barracuda Fastback.

Ah gotcha!

I just tried to find this, but it's not valid. Price has not changed, that I can tell.
     Has anyone confirmed this? Because I can get a price match on the ones
 I just bought last month.
