I want to run a 28x10.50 slick. Will they rub? I'm guessing I need a 15x10 wheel. What back spacing do they need to be(7.5 maybe) I don't mind pounding out things here and there just not sure what will work and what wont.

 

Yes. But if you mean a 28x10.5-15W, you will have to do some serious pounding on the inner fenders.

15x10 wheel, 7.5" BS. I ran QTP 28x11.5-15's with no problems until trap speeds went over 125mph... then the tires were growing enough to start hitting the edges of the wheel opening. Just moved the axle back about 1/4" and let the tires "radius" the rubber bumper cover.

 

i cut out the bump stop support and pounded in the inner well in front of the rear tire. fred is right.... i am running the 'w' on my car.

 

I forgot I even posted this. Thanks for the input guy's. I dought I'll put a W tire under this car but, you never know.
