18X8ET30 / 18X9ET39, do they fit?
225/40ZR18/RF 92Y on a Wheel Size Range of 8.5x18 (Front).
I want to make sure the ride will be smooth and no vibration is caused by these wheels.
Thanks!

I'm running the stock tire sizes you listed. I believe the stock wheels I replaced are 7.5x18 and 8x18....................... f/r
There was some minute rubbing on the fronts. The wear point was on the forward center of the wheel well covers. This was due ( I believe) to the worn OE struts that were being run outside their design limits with the lowering springs.
I think you should be fine with the setup you described.

It was very minute and I never felt or heard the rub. I coat my front wheel wells with the same coating I use on the tires, so it was easy for me to see there was some rubbing. I believe the rubs were occurring when turning and shifting the load on worn struts/shocks.
If you don't have the combination of worn shocks and lowered, I doubt you will have any rubbing. Like I said, the rubbing I "had" was minute. New struts and shocks are now installed. The last time (about 2 weeks ago) I did a quick once over of the well cover, I didn't notice the usual place with an absence of coating.
You shouldn't have a problem.

On a side note, do you rub when you have items/passengers in the back?




The front wheels are pushed to the edge of the fender and, IMO, are perfect.
The rears could set outward a bit more. I tried 12mm spacers once but 12mm is too much as I could feel a difference in the handling and road feel. I will try the 12mm again in a couple months; now that I have good shocks. But I think 5mm or 3mm spacers is what I would need for the rear, as the 12mm also put the tires too close to the fenders for me.
I think that would make the rear offset 30 or 32 and I think that will keep the tires just inward of the fender inner edge.
