The right tire offset?
 

I was wondering what is best to have your tire stick out farther then your body of the truck. In other words make the tires wider is a wheel that is -12 offset good to have the tires stick out farther then the body? Please let me know what you people think i really need help. Thanks

You know your are a red neck if
 

If you don't mind rock chips and dirt all over the side of your truck then you have the first hurdle down. The next down side is that you will look like you got a real good deal on rims that fit another vehicle. I do not believe that there is a up side on running them out of the wheel well.

But i want to well not all the way out just a little so they are wider you know like on lifted trucks the tires are always wider what are the best rims for that and is a -12 offset rim a good thing to make the tires stick out a little more.

if you run a big off set with big tires you run the risk of tearing up the berings

If you still want to run your tires out of the wheel well after reading the above entries, then the thing you have to look for is to make sure that the front tires do not hit the rear edge of the front wheel well's. When you turn with low back space rims like you are describing, the tires rotate rearward when you turn and likely will hit a factory opening. The fix is cutting the opening larger or more practically, use the correct back space rims that fit the vehicle. You will find that you can not deviate much from the factory rim back space dimension, especially with larger diameter tires.
Good luck on your project

What you can also do instead of cutting them is to take something like a bat and roll the inside edges against the outside of the fender. I had to do that when I put wider tires on the back of my 70 Ranchero.
