Hey guys, I need help; I bought my 2016 GS AWD F sport used back in August of 2019. The roads in NY are horrible, I'm spending more time and money fixing the wheels from get bent from hitting potholes. The 19" wheels on the F sport are beautiful, but are too soft to endure NY roads. The tires don't have enough thickness to absorb the shock and it's terrible. Just like me question states in the title; Can the 18" wheels and tires that come on the standard GS fit properly on the F sport and will the ride quality be comfortable enough to survive the roads of NY?
Thanks

Yes the wheels will fit. But the F sport is firmer.

The GS still comes with 17” wheels in Japan as standard as it gives a very nice ride.

Thank you so much I really appreciate the response

In addition to 18" wheels, you can also use bigger tires for better comfort: 245/45R18 instead of the factory 235/45R18.
Many have opted for that with nice things to say.

I still have 235s on mine, but I intend to replace them w 245s when they're done.

That is precisely how i felt when i drove an F-sport with 19" wheels ... roads in NY eat up the tires, wheels and suspension. Downsizing to 18" and getting a touring tire like these Pirelli's: https://www.tirerack.com/tires/tires...ll+Season+Plus will help tremendously.

18" OEM Lexus GS wheels will fit the AWD F sport with no issue. I have 18" wheels on my non F sport with Dunlop Signature HP tires and find them to be way more comfortable than the sportier Dunlop SP tires that came stock. Actually, you may even find that switching tires alone and staying with your current 19" wheel might be good enough depending on the tire, its sidewall and overall composition.

Do you know if Costco allows you to upgrade to bigger tires? I heard from someone that they only let you put on stock size tires. I think 245 is my next tire choice, but still want to get them through Costco if possible. Thanks.

Thank you for the information, I appreciate it very much

Has anyone tried 235/50/18 ? It adds more sidewall while maintaining the same width. Of course this also increases tire diameter to 27.25. The diameter of 235/45/18 is 26.33. Aside from the 3.4% speedo error will this cause rubbing or will the added weight cause problems with the F-Sport AVS suspension?
