Wanna hear somethin stupid? Just for sheets and giggles, I called my friend who works at a testing station, just to see how rediculous this law is. My 2001 Ford Taurus came stock with 205/60/16's on it. Last time I replaced the tires, they had a less expensive, better tire in a 215/60/16, so I got them. Asked my buddy about my care being legal and needing mud flaps, and...............it may be legal, kinda, depending on who interpretes the law. My car does have bigger than stock tires on it, so legally, should have mud flaps now. However, it has a small extension of the plastic body trim, that hangs below the fender just a bit, like a permanent, built in flap. According to my testing station buddy, some officers may consider something like that to be a type of mud flap, while some, would say that it is just a piece of body trim, and that my car now needs flaps to comply with the law. The laws says I need mud flaps on my passenger car that already only sits 6" off the ground, even though about 60-70% of the tire is still inside the wheelwell?
On to my truck. It's an '86 F250, no lift, cut fenders with bushwacker flares, and 315/75/16 BFG mudders. Legally it needs flaps because of the larger than stock tires. I have about 60% of the tire or so below the fender, but with no lift, it doesen't really look like it has that large of a tire. My brother has a '06 Dodge with stock 245/75/16 tires with no lift, although the rear of his truck is typical Dodge, sits pretty high is stock form. His truck from the factory has as much, if not more tire below the fender, than mine does, and came from the factory with no flares, but his is perfectly legal, cause he still has the stock tires on it.
My buddy was laughin his butt off when I told him of this thread, and told me he has had quite a few people freak out on him when thier vehicles didnt pass for things like mud flaps and fender flares, which he can understand, but has to follow the law to keep his job.
