E-Body Tire Combos

[6PKRTSE]

I can't remember without going thru all 75 pages of this post if I ever posted any or not of my Challenger? I have Weld Magnum 2.0's with 15X12's on the rear with M/T Drag Radials with a mini tub and rear springs relocated with Caltracs & split Mono-leafs.

So on a stock cuda e-body rear end and springs what the max backspacing that can be used without rubbing? 4.5?

[Aracer]

On the rear, you can always add a 1/4"- 1/2" spacer to adjust the tire to spring to fender spacing. It depends on the tire side widths.
And math.

Messing around in the shop, I was able to put 315's on the rear and 275's in the front of my challenger!  Looks great to me.  It does have a b-body Dana so there was about an inch more space on each side of the rear.  Fronts fit great.  Don't know the specs on the offset (just had them in my shop), but they are 17" wheels.

Looks great, I have 315's on the rear of my Cuda but I have mini tubs.

Looks awesome!  No tubs in mine...just had to trim the quarter lip.  LOVE 315's   I try to put them on all my muscle cars!!

Thanks. I was shooting for 335's like on my Viper but couldn't get there

After years of combo's, I finally came up with what I thought was the perfect set-up with BFG's on 15" rallye's.
Car is lowered all the way around with the biggest torsion bars MP had for circle track racing, and hemi leaf springs in the rear - KYB shocks.
Fronts fit fine, I had the rears made to get a 1/4" clearance from the leaf springs and just clearing the fenders after rolling them.   
I would have to dig out my notes for specs - its been about 25 years.
Car handled well and looked perfect!
 
front: P275/50R15 (25.825" dia)
rear: P295/50R15 = (26.61" dia (24.9" OE) x 3.55 = 3.301 effective ratio) 

Now I need new fronts & they are discontinued!

I've thought about doing that with my cop car rims as well as I have rallye caps laying around. You had to drill out the cop car rims to mount the centers correct?

negative...they bolted in.

Mine bolted right in after some trimming of the mounting studs on the rallye centers. The police wheels had three predrilled holes in the hub. I used slightly shorter bolts to mount them. Pretty easy to do.

1970 barracuda. ordered the wrong rims for the rear. but will they fit the front? 15x8 4.5 backspace

[70chall440]

They might but a 4.5" back space might cause you some issues; mock them up and see.

Here is a pic of my T/A challenger with 295 50 15's on 8" rallyes

Will this set up work with out rubbing  ? 15x10's rear with 5 back spacing   for front 15x8 with 4 1/4  backspacing ?
