Wheel offset and backspace questions
I have a 2003 FX4 and I am currently ordering the Black Cragar Soft 8's for my truck. I believe the stock wheels are currently 16 x 7 with a +12mm offset right? If I go to an 8 inch wide rim and keep the +12 mm offset, it'll give me a 5 inch backspacing. Is this gonna rub if I go to 265/75/16 from the stock 245/75/16? I've done some checking on my truck and it "looks" like I won't have a problem but I am hoping somebody has done the same thing and tell me for sure. I've also cranked my torsion bars about and inch or so last year.
My other question is dealing with lug nut length. Currently, the stock lug nuts have an overall length of ~1.5 inches. Has anybody else needed to buy new lug nuts when going to a steel wheel? I have a concern that the stock lug nuts may bottom out because of the decreased flange thickness associated with a steel wheel compared to an aluminum one. The problem is, the longest lug nuts I can find from Summit are only 1.400 inches. Should I even worry about it? Should I get open ended nuts just in case?
Thanks for all your help!
