My tires stick out about a little over half an inch and I have been cited for mud flaps and fender flares twice. At least in the CA vehicle code its a gray area, and they use that to ticket people. I just run mudflaps though, screw fender flares.
I moved from cali 5 years ago. I drive past the cop shop 2 times each day in my runner and previously in my Jeep with no fenders on the front and never had an issue. It's a shame how stiff the police and gov't are now down there cause it's beautiful but I finally had to bounce.
PS. In Idaho, Washington, Montana, Wyoming, and other free states it is a citizens right to be able to obtain a concealed weapons permit as long as you are not a felon. Try to get one in Ca. as a private citizen. Kinda rambling but I felt I had to leave.
