15x8 Rallys with 33x12.5 .. where will they rub on 2wd?

[cyberpine]

I know it's been discussed, etc.

But I was talking to this guy who assured me the rubbing on my 2wd 87 C10 would only be on the outer front lower edge.. but he was basing this on some 15x10 cragars with less backspace than stock Rallys.

Regardless of where it will rub or if the tire is too wide for the rim.

My question is, will the much wider tire on the stock 15x8 Rally rub on the arm bracket on the back side of the tire? right now I have 31x10.5 mounted and only see about an inch of space between the tire wall and the arm bracket. If it makes it, it will be really close.

thanks for any help or information.
