2017 GS350 wheel question
Hi all! I recently purchased a 2017 GS 350 and just found out my wheels are F Sport. My car itself does not have the F Sport package (grills are standard, not meshed and doesn’t have the F Sport emblem anywhere on my car). So I’m wondering what does having F sport wheels mean? I took my car to my local Lexus dealership to get serviced recently and an advisor noted that to me. Does that cause my car to burn more gas?

Welcome and congrats on your GS!
It's just a style of 19" wheel. No real difference in mileage, but as they are a 19" wheel, they have a half inch less sidewall height than the 18" wheels, so some find them to be firmer and have detrimental effects to the ride quality.

Previous owner decided to change the wheels to f-sport. You won't be able to do a 4 wheel rotation, so the life of the tires especially in the rear will be reduced significantly compared to the front. Honestly for this car on the street, normal driving, these aren't going to provide any real world performance advantage, basically for looks.
For the best ride quality the factory 18" rims with up-sized tires 245/45/R18 gives the best ride quality, also extra pothole protection, that's the setup I'm running.

Be careful with a staggered setup on AWD. It can work, as Lexus offers a staggered setup on the AWD IS, but you need to look at tire sizes and ensure the diameter of front and rear tires are close.

Thank you. Could you let me know what I should look out for? I love cars but not very knowledgeable on it.

I'll need to look. If I remember right, you need your front and rear rolling diameter to be within something like 2% of each other (I'm certain 2% is wrong, it is a little higher or a little lower). If you take your front and rear tire sizes, you can search for an online tire size calculator which will give you the diameter. Then you can compare them.

If they are real, they're forged BBS if I recall correctly. You should be able to sell them for decent money.
If those still have the factory tires on them, you should take them off as soon as possible and avoid driving the car as much as you can. Factory tires for the RC-F are 255/35/19 front, 275/35/19 rear, and there is a 2.3% difference in diameter front to rear. That difference in rolling diameter is putting strain and wear on your AWD system.

What are the current tire sizes? From the blurry picture I believe they are the OEM Michelin Pilot Super Sport tires but hard to tell.

You've got the same 245/40 and 275/35 combo that I have which are closer in diameter than the 255/275 OEM sizes.
I'll let the AWD guys chime in on if a 0.4% difference makes sense. You might be ok!
Also, swap out the Premium silver center caps and get some darker executive or F-Sport center caps!
