15x12 rally wheel? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

69GMC910 · 07-12-2011, 07:19 PM

Will they fit on a stock lwb? And if so, what backspacing is ideal?

Please let me know where you have found them.
I would say 6-7" of BS should work depending on tire size. I am looking into running a 15x12 but haven't found a 12" rally. The tire I plan to run is 29x15r15 MT Sportsman S/R.

You might have to modify your tub if you want a really big tire

3r!c84 · 07-12-2011, 07:59 PM

My 10 inch wide rim and tire combo are the limit IMO. They rub the inner tubs on hard turns. And yea where did you find this 12" wide rally?

I am attempting to order them through Wheelmaster Classics in Calgary... He's a distributor for Wheel Vintiques... He is getting back to me tomorrow with their answer as far as "will they do it". He cannot see why not as they offer a 15" corvette ralley in 10,12,and 14" and they both share the same diameter center section of the wheel... Currently with my 15x10"/5"bs with 295/50/15's there is about 1 3/4" of space between tire and wheel well. That being said, if I am able to order a custom backspace, would 6" be ideal? I want to run the MT S/R's as well, 30/12/15 or wider if possible..

69GMC910 · 07-12-2011, 08:11 PM

@ 3r!c84, what tire combo are you using?

3r!c84 · 07-12-2011, 09:48 PM

315/35/17 not a 15 inch rim but still 10 inch wide. im running the max width i can fit
btw are you lowerd?

69GMC910 · 07-12-2011, 10:36 PM

No I'm stock height right now. Those tires look sick!

Top Banana has two setting in the show room but not for sure what the back space is.

69GMC910 · 07-14-2011, 09:59 PM

Can't decide on proper backspacing for a stock height lwb... Ordering hinges on that...

69GMC910 · 07-15-2011, 10:30 PM

Anyone running a 12" wide wheel on a non lowered truck? Backspacing PULEASE!!!

**lolife99** · 07-15-2011, 10:37 PM

15x8 wheel has a 4" backspace.
15x12 wheel will need an 8" backspace for the outer edge of the rim to end up in the same location as a stock wheel.
This will require mini-tubbing the bed.
(A 7" backspace would probably work also)

ratrod67 · 07-16-2011, 11:36 AM

15x12 with 7 inch backspacing. Bed floor cut to the frame.

kris's66lwb · 07-16-2011, 12:05 PM

I put 31x 13.5 `15s on my lwb but i also had 15x8.5 inch wheels i had no rubbing issures with that size tire and looked *****en i dont know the backspace THEY PRETTY MUCH STAYED IN THE STOCK LOCATION THO

softballnrd27 · 07-16-2011, 02:53 PM
