According to the state I've got to cover the tires completely with the fender flares, even though I've got mud flaps. I'm not sure what my backspacing is, but my tires stick out about 1" or so past the stock flares. I'm just afraid that those 6 inchers will stick out too far for my liking. Pics will be great if you get a chance, the width of your tires is similar to mine so it should give me a ballpark of what it would look like. Thanks!
