How small of an offset can I get away with on a 15x8 rim?

I am looking at 15x8 steel wheels with anywhere from a 2.5 to 3.25 inch backspacing. I don't like the way 3.75" BS on a 15x8 looks. I don't mind my wheels sticking out on the sides. I actually prefer it. If I have to slap on bushwhacker fender flares to keep the fuzz away, I will.

It seems like no one is running these. I understand that there will be more wear on wheel bearings and CV joints, etc.

I know I will not be rubbing on the frame because my wheel will be pushed out compared to the stock 15x6 positive offset wheels. I'm more worried about rubbing my right tire on the outer corner of the fender when at full lock to the left (and vice versa). Has anyone done this? I know people are running 15x10" with 4 inch backspacing, but I think those members are running them with fender / bumper / suspension modifications.

Thanks for all of your help!

Also, any suggestions for alloys with a 3.25 backspace or smaller on a 15x8 with a center bore big enough to accommodate raider hubs (108mm) are appreciated! I am not married to the idea of steelies, but realize that my application may limit me to them alone.
