i understand the offset thing but the rims im thinking about getting (XD Rockstars) on rimzoneonline.com show either a -0 offset or a +0 offset whats the difference between the two or isnt there a differance.

 

-0 and +0 are the same.

 

Are the 04+ F150's hub centric or lug centric?

 

THe oem 04-08 wheels are hub centric but most aftermarket wheels for them are lug centric. You can buy hub centric rings to use with lug centric aftermarket wheels.

 

I am having a hell of a time getting my wheels to balance properly. Would this have anything to do with it? Wheels balanced but being mounted wrong?

Keep getting different opinions from different shops. Static balancing is the problem. Rim is bent. Tire is bad etc etc... At highway speeds the steering wheel shakes.. Which means problem was in front. Balanced tire and moved to rear now rear still sakes. Got new rim and tire and while not as bad truck still shakes.

Latest I got is now the other 3 rims need to be dynamically balanced like the new one..

 

Some members have reported that hub centric rings solved their vibration issues. I'd try them and also have the tires road force balanced.
