drive with one wheel on a ramp and you´ll see.
if your rims have the right backspacing there will be some more space under the flare.
i have 32s and 8" (20 cm) between tire and the flares. and it doesn´t rub. but when flexing the tire needs the full 8":
EDIT: and there's only 3"-4" before my axle hits the bumpstop: http://jeeptj.de/viewer.php?albid=14...e=3&imgid=2216
i think you´ll have some rubbing.
