Correct! The 18x9" ET30 can work up front, but will require a touch of negative camber. Typically -1.8 or more is required to fit that wheel up front. In the rear, I would suggest going with the 18x9.5 ET22 as it has the same concavity as the 18x10 ET25, but will suit your 255 tires a bit better. You will not be at risk of rubbing when you upgrade to a 265 or 275 rear when running the 18x9.5" ET22. The 18x10" ET25 may require a fender roll with 275's.

Here is an image of a flat faced from and concave rear wheel:



Let me know if you have any other questions!

Perfect, 18x9 ET 30 (front) and 18x9.5 ET 22 (rear)

Thank you.
