Just to help clarify something mentioned earlier. Bobby mentioned he has run 28x12.5 ET Streets with no problems. I'm assuming he means this tire. MT # 3755. They are not actually 12.5" wide tread, MT gives the DOT tires a different size rating than their slicks. I too run that exact same tire, (part# 3755)
Here is what Jegs has to say about that tire.
Mickey Thompson ET Street Drag Tires - JEGS
It is really a bias ply 28x10.5 slick, with a different sidewall size , grooves cut into the tread and a DOT number. Click on "More Details" next to part number 672-3755 for the actual numbers. I have run and currently run this same tire on 15x10" rim with 4.5" back spacing, but it will work just fine on a 15x8 with 3.5" back spacing.
All the Weld 15x8 rims I have run in the past, have had 3.5" back spacing. I had friends who've had trouble with 15x8 wheels that had 4.5" back spacing. They always seemed to rub really bad. As far as bolt circle goes, our cars have the 5 on 4 3/4" bolt circle and take 12mm x 1.5 thread lug nuts for stock wheel studs. You will need the long shank lug nuts with washers for Weld Draglites or Pro Stars.
Front rims, you want the 1 3/4" back spacing on the 15x3.5 wheels, or 2 1/4" on the 15x4s. You can run a race series tire from any of the tire companies like MT, Hoosier, Goodyear, Phoenix, etc, etc. Some people also run VW size tires up front as well. Something like a 165 - 175 /75/15 tire, but personally, I don't particularly care for that short of a tire. I prefer a 27-28" tire up front when running a 28" tall rear tire.
Hope some of this helps.
