Here's the deal. Since I put Nitto 285/60R-18s on my truck I get some rubbing on the mud flaps when I make tight turns..especially when backing up. I do not want to lift the truck. So, I have two options. I can remove the front mud flaps or "cut out" the area, on the extreme inside edge, where they rub. From what I have been told the rubbing won't hurt anything..just annoying. The tires do not touch/rub on the uca. My truck has no fender flares but instead has chrome trim around the wheel wells. If you have a Tundra with wider tires & no mud flaps I'd like to see some pictures. Thanks
