I have read most of this topic  and found lots of good information, but not that fits my situation.
I have a 73 cuda with stock e-body rearend. A street lynx 4-link wit the lower link bars attaching at the stock location. No mini tub, sock wheel wells. Ran out of money, will mini tub later on. Anyone have this setup. Can I fit a 15x10 wheel with 6.5  BS and a  315 wide tire?
Thanks Jimmy

you will have a good inch of fender lip clearance, might be close on the inner fender wall, with no leaf springs that should be you limiting factor, I have 15x10 5.5bs with 295's on 1" relocated springs, tight on the fender lip, plenty on the inner clearance, my springs are my limiter, Ihave about 1/4" to the leaf.

Hello, I've read threw quite a bit of this thread, but I just wanted to see if I could confirm this.

Although it might be a bit, I'll be looking at buying some 15x10 (back) wheels and fit as much rubber w/o cutting anything up on my 71 challenger. I have a b body rear end out of a 69 1/2 a12 Coronet dana with 4.10 gears, that I plan on putting in my challenger to help with tire clearance. I purchased the Dr Diff 1" offset shackles. He recommended I run a 28x12x15 (305x54x15) MT Street Radial on a 15x10 wheel with 5.5 inches of backspacing he said it will work w/o spacers if I use his rear disc brake setup. So the question I have is has anyone else done this setup? Not sure what to run in the front yet, right now I am focusing on the rear and making sure things fit w/o any tubing/cutting. I'm also looking at running the caltracs leafspring/traction bar setup as well.

Thanks,

Kris

Dr Diff knows his stuff, so you  would be safe with his combo. I have a very similar set up and have clearance both inboard and outboard. Mine is a 66-67 B body housing, 1" offset springs, 15x10 with 5" backspace ( the 68-70 would use the 5.5") and a 26x12x15 MT tire. No other mods at all.

Up front  I have 15x8, 4.5" backspace, 26x10x15 MT tires.



Just for grins, I have tried mounting the 15x10 combo up front. They are gonna require fender surgery to work up there. This is where a 17"+ sized rim would help. The max backspace you can run on  a 15" rim is 4.75 before it contacts the ball joint. Larger diameter rims would clear this and allow more backspace so there is less tire sticking out.

Thanks for the reply back. So you are running a 26x12x15 at the rear (Not 28"s tall?) I'll shoot for running what he told me (28x12x15) just wanted to see pics and confirm fitment if possible. Maybe it's me, but it seemed like there are more wheel choices for 5"bs vs 5.5"bs. I need to look more though. As for the front, I'm not overly concerned with putting the biggest wheel tire/combo up front. I just want to make sure I can turn the wheel fully w/o rubbing.

Yes, I've limited height to 26" all around. However, a 28" tall tire is only 1" larger top and bottom, so still not a big interference issue. I may run 28" when I wear these out, unless something new comes to market.

Backspace, options really vary among different manufacturers. With cast aluminum wheels you really are stuck with what they have. No chance of them changing molds for a special request. Forged, 3 piece or steel wheels tend to have a lot more variability and options for custom spacing.

I would stick with the Hoosier Quick Time 26x12x15, it looks good on a Challenger.  I had 28x12.5x15 Mickey's on my car and didn't like the look with 26" in the front.  Too much rake.  Check out Hoosier for that 26" tall 12" wide tire, Mickey unfortunately discontinued there 12" wide 26" Sportsman Pro, but they have other radials close to that.

Here's the 275/50-LT15 Hoosier Quick time... 26" tall and 12" wide.

Cam you rum a 295 or 315 width tire on a 9" wude  rim?

Thanks jimmycuda71

Here's the 275/50-LT15 Hoosier Quick time... 26" tall and 12" wide.

Please advise me - why go for such a fat tire? Maybe my question sounds stupid, but give me a break - I'm from Central Europe, we don't get muscle cars over here. 

So, why not go for a 17/18" wheels with thinner tires instead of 15" with fat ones? Is it to be drag raced, just for looks or what?

BTW, I checked, even if I wanted to get tires like those, I'd have to order them from somewhere because they are not available in my country.

I guess, I assumed you were running or thinking of running a 15" wheel.  I can give you advice on 14" and 15", the other's I can't because I've never tried to run them.  People who run larger aftermarket brakes usually run the larger diameter wheel, thus the advantage there.

It comes down to what you like.  I prefer more stock/Day 2/70's look, so a 16" will never be on my car.

[Archialfa]

Yeah, I planned to go for 17" in front, 18" in the back, but then I saw this thread and started thinking maybe 15" is the way to go... I didn't know if there is any other reason except looks. The grip is the same or...?

Tire choice for 15" is very limited, does look good tho...

[JAS]

The questions you are asking there are many answers to.  Ride quality, handling, etc. all come into play with different arrangement.  Something to keep in mind in general, the shorter the sidewall, the harder the ride ~ not necessarily better cornering, that has more to do with tire choice and compounds... see what I mean about different answers?
