Hello Folks. I'm looking to change my stock 2009 Tribeca wheels with Stock 2017 WRX Wheels. The WRX wheels are 18x8.5 while the Tribeca's are 18x8. The offset on the WRX wheels are 55mm while the Tribeca's are 45mm. Anyone have any experience with this?

WRX.
18x8.5
OFFSET 55

Tribeca
18x8
Offset 45

Hmm, I thought the Tribeca had a 55 offset too. But I'm sure you did your research so if this is correct that'll put your tire 12.5mm closer to the struts if my math is correct. Sounds like a pretty big difference. I'd try to see how much space you have first.

I've seen it written in a few places as 55mm offset but most manufacturer websites say 45+. I found a few other posts of guys that did it with the same wheels. I did it and just drove 50miles. No rubbing and ran great.

Offset is 55. It will be on the inside of your wheel. Size and offset will be in different places. I checked my stockers to make sure.

I am in the market for WRX 18" wheels like above. Any suggestions, I would like even wider wheels than the 8.5 width of the WRX rims if possible like 9.0 wide and an offset of 45 rather than 55 as stated to push out the wheels slightly. If any member have pictures of this type of setup please submit your cars stance. The idea is to widen the stance slightly to reduce weight transfer in the corners.

You can add wheel spacers to push out the WRX wheels to an offset of 45 by adding 10mm spacers. This does add unsprung weight, but does widen the stance.
