They don't make a DR that I know of in a 28x11.50r16. I certainly could be wrong. A radial should be on a wider wheel then the bias. It would probably work if they made the size in a radial but a radial isn't as forgiving as a bias so the contact patch would be much more effected.

Are you guys running stock diameter fronts mostly, or matching the diameter of your slicks?

I had tubes in mine but they weren't screwed since I only cut 1.8-1.9 on nitrous. If you are running tubes make sure to screw them.
