DOT Drag radials on '03 2500

[destey]

I got a 2003 Chevy 2500 I was thinking of putting some DOT approved drag radials on for street use. Basically, I can't get traction with my stock tire setup. I've got hptuners with a 150 shot of nitrous and I can't keep the tires from spinning.

Issues:
- I've the 8 lug pattern, most drag rims have 5
- fitting tire/rim in there
- 16" rim is as small as I can go, I think, with the brake clearance

Any ideas of what tire/rim setup I should go with? I was also thinking since I have 2wd to go with small drag looking tires up front. Any ideas?
