Got the new tires put on today, 265/75/16 Kumho RoadVenture AT51's. Having an issue with rubbing on the front left. Rubs the front bumper and inner liner. Left side doesn't do it though. I tried to adjust the bumper forward as much as I can and it still rubs, there is a difference in the gap infront of the tires to the bumper on both sides by about 3/8 to 1/2 inch. Is it just an adjustment issue with the bumper or something else?

 

There is a support behind the front bumper fascia that kind of looks like an accordion on both sides. It will collapse a notch (or more) when you bump or hit some object in the front. I had to replace that part when I first put on larger wheels & tires, I was unable to turn at all due to rubbing on the front fascia on the right side. I had to put my old wheels & tires back on until that part was replaced. You will have to remove the front fascia to see if that is your issue.
