I had warn fender flares put on my Ranger last Dec., paint to match.
Love the look!! I have been back to the dealership 3 times because of the poor adhesion to the fender.
I have 275/70 DuraTrac on Black Rhino 18 x 9.5 with -.18. I have cut my bars and I rub the felt fender liner when I am at full turn. I have not gone off road yet but I will find out in the next week or two...
