so if i get the 4" backspace i don't have to worry about anything?

 

[pontiac dragger24]

would i be able to get away with a 4.25 bs or will that hit?

what off set should i get the ones I'm looking at have -13 but which one would i need i just need to know what will fit my wheel wells and not rub

15X8 with a 4" BS is probably the ideal size for a 255/60. A 4.5BS would allow you to fine tune the frame spacing with longer studs and spacers, but 4" should still keep the tire mostly off the fender lip.

what off set are you referring to
any of them from here work?

-13 offset on an 8" wheel is basically 4" BS.
