so someone here told me that there was a bump on the left wheel well plastic towards the rear of the wheel well cover that was causing the rub. look at the red arrow.
the blue arrow is also where it rubs a little. i was getting run only on full left turn lock with 285/60/20 duratracs in normal and entry mode heights . stock wheels did not rub in any mode.
the fix was easy with a heat gun. I heated up the bump first "red arrow" and just dented it in and held it with a gloved hand until it cooled. the blue arrow i heated the area so hot that it was slightly melted and pushed with my gloved finger tips and really worked the area until in pushed in and cooled. make sure you have thick gloves on or use some type of device you can push the area in with. i don't get any rub on normal mode anymore. in entry mode i heard an ever so slight rub, but i was really listening for it. problem is solved. so if you want bigger tires go for it, its not the width that is the problem is its the height. the bump was there because of some electric junction box. this method did not affect that box at all. the picture above is the before pic.
