I have been obsessing about the rear tire size on my Barracuda.� I think I have decided that I want to try to stuff a pair of 295/45 on 18x10 rims under the rear.� So far I have the car set up with the 3/4 in relocation kit and a B-body spec Moser (Dana) 60.� I am I thinking unreasonably on this?� Does anyone know what obstacles I will still encounter such as mini tubing or rolling the fender lip?� Also, what backspacing should I be looking at?

Anyway to get the dimentions of that tire in inches?

that would go along way in figuring out the wheel offset

Inflated diameter is 28.31 inches and width is 11.54 on a 10 inch rim.

HemiD,
that's gonna be a close call 28.31" diameter!! Make sure your backspacing is very well set, otherwise you'll rub the rear quarters!!! The problem is not on top of the quarter panel but like looking directly from the side of your car the worst place is like 2 o'clock position in the fender. 5,5" backspace with that tire might just fit ok, but not too much to play with (At least with Chally that's the case but the rear quarter wheel opening is a bit different). 6" backspace should be fine.

I also checked from a friend his Cuda setup, he's having same MT's 28*12,5 and hes said that's absolutely maximum that fits into wheel base. Frame is slightly wider in Cuda so 12.5" width is tight fit.

I figure it is going to be really close and I might have to do some mods to make it work. Just like to get a good idea of what I am getting into. I don't know if you have seen the Challenger in Popular Hot Rodding, but that is the combo he is running and I love the stance and with the power I am planning on pushing, the added width would be welcomed.

I dont care what size the rim is 15/16/17/18...28 inch diameter is 28 inch total diameter on any rim......11.5 wide shouldn't even be close to a problem.....'

my diameter 28.1 ---12.6 wide on 10 inch rim...but i have an 8.5 which comes out to 12.0 wide sidewall to sidewall....and it just rests against the spring and plenty of outer lip clearence.......and i havent put on my relo kit yet on an e body rear....how ever i am going to run a b body so i will have a little more room...

it is 5 inches of back spacing.......Centerline Convo Pro
Mt et street Tire 28*12.5*15 on a 8.5 inch wheel with 5 inches of backspace on a e body rear and relo kit fits perfect....but change to a b body and 10 inch rim to get a little more meat.....me personally i like the low tucked street bruiser look.....

:dontknow:
I'm a bit confused, I have been reading many of these threads on this subject and I don't get how you can get a wider tire on a B body rearend just by installing 10" rims once you put the B body rear in. Aren't the springs still in the same place as before� or are you moving them in still further?� :

360 'CUDA · « **Reply #10 on:** December 02, 2004 - 08:44:22 PM »

The B-body rear has a 1.5 inches shorter track and the spring seats are 2 inches closer together

That moves the springs out of the wheelwell (when viewed from above) when used with the spring
relo kit and A-body sized springs... super stocks ect

You get alittle more then 3/4 inch extra on the inside on each side

That puts the 5.5 inch inset wheel close to the spring depending on the tire buldge but if the tires touch
a good 1/4 inch spacer will fix it. My thought is the tires wont touch the spring with the 5.5 inch inset
because the 18" tire wont have much buldge

PS wheel spacers are for wimps

Boyd puts them on his roadsters and he makes his own wheels :rice:

HemiD &8Pack,

you have to remember now that Cuda wheelbase is different from Challenger!!! We just went through it, Chally has about 2" reserve until the frame starts to rub and I'm already running 12.5" MT's
My friend has exac similar tire 12.5MT with 10" rim in his Cuda and Yes, he's having like I-I this much playroom until the tire hits the frame.. I mean the play room is so close that my finger won't go between the tire and frame.

That's why that PHR Chally looks pretty fine w/ that setup, So measure all the distances from fender to frame, spring to rim bolts etc.

I'm quite sure you're OK with 10" w/5,5" backspacing, BUT 12.5" is absolutely max i.e. your 295 should be fine. To get that 0,5" inner you're skipping the problem of tire rubbing the quarter reat the tire in 2 o'clock position with that 28.31" diameter.

That's the same car from the January '05 issue of Mopar Muscle. I found his web page a couple of years ago -----> http://users.anet.com/~sdurr/ It has a pretty interesting story. He has traveled a long, long road full of crappy mishaps to get where he is as. I think most people would have either gone broke or just quit, rather than go through what he has. His tire/wheel combo is pretty sweet though!

Damn... and I thought i had some hard luck with mine

This guy really kills me with the experiences, even though a serious stuff but I was just laughing my @ss off because really, you can't have this bad luck continuously.. well this guy seemed to have.

But that's what you eventually get with blower stuff, blown rotatings and cracked blocks... as they say, let's see how's the tuning, if the power doesn't fly to the wheels, at least the rods and cranks fly away

Thanks a lot guys for the info.� I keep thinking I am ok with that combo, but it makes me feel better to hear if from some people with more experience than I.

I was thinking the samething about that guy too.� That is some seriously bad luck and hard road to travel.� I hope my project doesn't play out like his.
