Hello, I am playing hell trying to find MATCHING TIRES for my 2015 GS 350 F sport, it has 265s out back and 235s out fron on 19's ,
are there any SLIGHTLY larger sizes that will fit on my stock wheels/rims that will give me more options to choose from. curretly the only ones i can find that all 4 match are the potenzas and the contis..I was looking for a quiet / soft cushy ride. ..
any help is SUPER appreciated ! ! !

Honestly I don't think so. If you size up to 255 in the front you will have rubbing issues even at stock height. I don't know if you can size down to 245 in the rear without a lot of stretch on the 19s.
For what you want I think you need to find a square rim set up.

If you have a RWD GS, you can run a square tire setup on your staggered F-Sport wheels. You can go 245/40/19 all around. That size tire will fit wheel widths between 8"-9.5". F-Sport front wheels are 19x8; rears are 19x9. Helpful threads:

Going the same size all around might be possible, but a couple of things to consider:
- The rear tires will likely look stretched especially compared with the front. And a stretched tire will likely have a lower profile. So visually, they will be different.
- Rotation, with the rear rims being wider, you may not be able to rotate your wheels, not sure, but the wider rear rim may cause clearance issues up front.
If you’re going to run square, I say do it right, and get 4 rims of the same size, tires fit the same, look the same, perform the same, and can be rotated. Regular rotation and balancing also helps prolong the life of tires. So a proper squared setup with identical wheels and tires at each corner will likely be better in the long run. Just my opinion.

Damn np... I just deleted my message because I realized I posted almost the same thing in a different thread, and didn’t want to be seen as “preaching” on this issue... but you quoted me before it was deleted. No big deal...
I will I’ll add though, I’ve found 2016-2018 F Sport front rims in the low to mid $300s. It’s a good chunk of change, but if the plan is to keep the GS for a long time, I think it’s a good investment.

@np20412 & @chinee are correct to state that you cannot rotate wheels on a RWD GS - the staggered OEM wheels do not allow for rotating wheels/tires. Lexus maintenance guides clearly indicate that they only rotate tires for those models with same size tires/wheels. That also means just b/c you get a square tire setup, doesn't mean you can rotate wheels.
If you get a square tire setup, since the rear wheels are a little wider on the F-Sport, you might see some "stretch" but depending on the tire, manufacturer and model, it may look stretched, it may not. All depends on the tire itself.

I think the rear tires at 265/35 have been easy enough to find but the fronts at 235/40 have been a little hard. If I size up the fronts to 245/40 do I have to size up the rears as well or can I keep them where they're at?

You don’t have to but you probably should upsize the rear to 275/35 so that the staggered ratio remains relatively the same.
