Any one running 15x12's?
I'm getting ready to order a new set of Weld Magnums for the rear since I'm having the rearend narrowed 3" on each side. Is anyone running a 15x12 or do you all pretty much stick with a 15x10 with 5" backspacing? Additionally, if any of you are running a 15x12 what backspacing should I get for that size? I'm gonna stick to a 28x10.5x15 ET drag if it matters.
Thanks guys!

I would stick with the 10's...I don't know if you can get too wide a rim, but a guy around here did it and it looked wierd and he had a good bit oftraction problems...went back to a 10 inch wheel and the problems cleared up. Just my opinion

i will be running a 15x12 wheel with a 29x10.5W tire soon but my mini tub is not done yet, you will need the tub unless you what the tire to stick out past the quarter panel.

check this out is you get the chance, it allows you to run a huge tire and rim combo that sits under the wheel well totally

Ya but which back spacing for a 15/12
I have a 3in on each side rear also and I was thinking of running 315/60/15 drag radials so I was kinda wondering what wheel if I went with a 12in wheel also. Has anyone done it and has it on their car and can say that it looks way good.

My car is minitubbed and I am also running the Wolfe adjustable spring perch. I know I've seen most people running 10" rims so I did the same. Maybe I should have went with a 12" plus I didn't know what backspacing to get. Summit was going to have to order them from Weld so it might not be too late to change my order. Does anyone have answer to this question?

Here is my take on the subject:
10" wheel with 5" BS = 5" dish
12' wheel with 5" BS = 7" dish
So if you determined a 5" BS is right for you it will be the same on a 10" or 12" rim.
How do you determine what BS you need? Climb under the car and determine what your tire sidewall will come into contact with first. If you are not mini tubbed your tire sidewall will contact the frame first. If you are mini tubbed your tire sidewall will contact the LCA first.
Climb under your car with a flashlight and tape measure and check it out. Check out your manufacturers web site and find out what your sidewall measurement is on your current set up.
That is my take on the subject. Correct me if I am wrong.
Here is a pic of my set up with a mini tub and a custom offset LCA. My wheel is 6" BS shimmed out with washers 7/8" to simulate a 5.125" BS. {My new wheels are not here yet } . My tire is a Goodyear 30" X 10.5" with a 13.0" sidewall.
You can see I have around 3/4" of clearance between my sidewall and my LCA. The side wall is nowhere near the frame, spring or shock. The LCA is my first obsticle.
You need to pay attention to the fender on the other side also. I have enough clearance to run a 29.5 X 10.5W with a 13.6" sidewall and I should still have enough clearance to lower my car.
Here is a pic of the spring clearance. Hard to see with the black background.
Hope this helps.

Also, I have been told you should not run a wheel that is wider than your tread. Check out the tire manufacturers recommended rim size for the tire you want to run. I always go with the recommended rim size.
Mickey Thompson 29.5 X 10.5W with 11.2" tread has a recommended 10" rim.
Goodyear 30" X 11.5" with a 11.4" tread still has a recommended 10" rim.
This is also on Goodyears web site which blows my theory out of the water
I went with a 10" rim and I may or may not run the W tire. I personally would not run a wheel wider than the tread. But thats just me.
Just my 2 cents.

Acceptable application for rim width is tread width plus or minus one inch

15x10 or 15x12
I ran a 33x10.5w on a 12" rim it looked fine to me, the 12" rim on something like a 315 60 15 looks weird i think, but the advantage is it pulls the tire out which allows you to run more air and have a tire that reacts faster and is more stable at high speed.

I have heard of relocating the LCA's inboard, but I kept the stock locations. None the less, the 10" wheels work fine and still look good too. I went with a 4.5" backspace due to all the wheels that offer that configuration.

Dopefed, if it's of any help I'm using a 15x10 5" backspacing magnum, wolfe minitub setup and will have my housing narrowed 3" as well. The tire that I'm going to use is a 29.5" tire.
