Suppose you HAD to run a 7" wide rim, what size slick could you run? 9"?

Something like a 29x9.0-15?

I wouldn't..It would not take long to use up the center of a wider tire on such a narrow rim...I ran some firestone 26x7 slicks on a 6or7"rim in my SC/Rambler with a 4-speed..left at 7k..ran mid 11's with that car..

Depending on the actual tire, I think you could get away with a 9". I ran a 10.5" Sportsman Pro on a 7" rim and, although it was way too wide a tire, it still technically worked and hooked pretty well with the right pressure. It actually didn't wear nearly as bad as I thought it would either.

I used to run an H&H Race Master G60/15 (8.2" x 26") on
15" x 7" steel wheels on my 71 Duster.

I'd say they fit perfectly. I wish I had pictures of that car.

I run 15x7 cop wheels with a 30x9 Hoosier slick..as stated earlier you will have un-even slick wear...i have 42 passes on mine and they are starting to wear in the center..you didn't say how fast you were going to go or how heavy of a car you are runnin,that will have an effect on how fast the slick wears.If you are going to be slower than 12.50's or so ,i would say that you would get avg. life out of the slick. ...I don't have a very good pic of my car with just the wheel and slick ,but this one willl show you how they look...

That's the money shot! Thanks!

It is about 2900lbs hopefully running 10.90's, but will probably 60' pretty fairly lousy.

I have been running 29.5x10.5x15 Mickey Thompson ET drags on a 7" wheel for years with no problems at all. I get a good contact patch and even wear across the entire tread. I wore the last set to the cords and they showed the even wear very well!! I would have liked to run a wider wheel, but a stock wheelwell, stock spring location, and no money prevented it from happening. I would think a 29x9 would work fine, even a 28x9. It may not be optimum, but with tire pressue adjustments you should have good results.

with the slicks i tried both ways with and without tubes at 14.5-15lbs of air pressure either way.no noticable difference in performance maybe a tiny bit more stable up top with the tubes.with the DRs no tubes 18lbs of air press.
