Anybody running a 18" rim and tire for winter, or am I stuck with 19"??...

I am curious about this too- EG, if I get a set of Base 18" GS350 rims, I think they should still fit over the larger brake calipers on the front of the f-sport but not 100% sure about that..... I don't think we are stuck with 19s at all, but 17" are probably out of the question because of the brakes.

I'm on the stock 18" wheels with my AWD 4GS with All Season Tires and have had no problems in up to 6-8inches of snow...

Just as reference, the AWD GS comes with the following non-staggered OEM tire sizes:
17": 225/50/17 (Premium Models w/o Wheel Upgrade)
18": 235/45/18 (Premium & Lux Models)
19": 235/40/19 (F-Sport & 2015+ Lux Models)

If you have an AWD model (f-sport or non f-sport), the brakes/calipers are the same regardless of the wheel size so any OEM wheel of that size (17x7.5; 18x8, 19x8) will work.

Like AJLex19 mentioned, 18" wheels should clear your AWD F Sport without any problems.

As a side note, if I skinflint and put non TPMS valve stems in the rims, will the car complain/whine at you, other than not displaying the tire pressure? Or does it basically just sit there with the lines on the tire pressure display? Those sensors aren't cheap, at least not for the good ones...
