18x9 moto metal black 951's with 285/60R18 tires?? I have an FX4 and was wondering if this would fit with the factory lift or not?

 

those should be right around 33" correct? whats the backspacing on the 951's you're looking at-
i think you will probably be okay- if they stick out a bit (backspacing) you may have to clip your front valence a bit...

 

They have 4 1/2" backspace and can go with either +30mm offset or -12mm offset.

 

You should be fine.

 

ive never bought any types of rims before so this might be a stupid question, what do the offset number mean?? is that how for the tire will stick out or s that the backspacing?

 

Backspacing and offset are two different ways to measure the same thing, if that makes sense. They both determine how much the wheel tucks/sticks out. Backspacing is the distance from the mounting surface of the wheel (where it bolts to the hub) to the rear edge of the wheel. It is much easier to understand than offset.
Offset is the distance from the mounting surface of the wheel to the center of the wheel.

 

agreed-
