as far as fitting and not rubbing it all depends on how much your truck is lifted/how far your axle is moved forward.. ect. i did find a website that listed recommended rim widths. mickey thompson recommends 11-13" wheel for their 15.50 width tires. putting that wide of a tire on where it wont rub your springs is gonna push it out far enough that your scrub radius is gonna be crap... but those were really cheap so it would have been hard to pass up..
