I can't say there's any significant handling difference due to the 1+ size, but there definitely is a significant difference is ride quality and quietness that I was looking to gain over the OE size and brand tires. I couldn't care less about gaining [handling] performance in a heavy luxury sedan that I don't track, but instead I carry a ton of golf stuff in the trunk.
I personally think more sidewall is better with the roads we have around here.

Besides, I think the 245 is cheaper than the 235.

Are there any options for the ones that came with 235/40R19? I'm looking to increase the meat on my tires without fender rubbing.

I can confirm OP's suspicions. I've actually been wondering the same thing. I switch off between driving the 2017 Lexus GS 350 and a 2015 Toyota Sienna. The Sienna would take forever to rack up miles, while the GS 350 seemingly racks up the miles almost 1.5x - 2x as quick. I initially suspected it to be the tire rotations and psi of the tire pressures. It was at 30 psi, but I recently pumped it to 33-34 psi and am still baffled at the mileage count. Something fishy is going on...

Edit: I guess what we can do is to start keeping a record log of miles driven every time we fill up the gas tank, and try to fill it up from a near empty gas tank. I'll keep you guys posted of what I notice.

I would suggest using an old stand-alone GPS, like my old Garmin, that has an odometer function to compare on your trips. If you drive any stretch of road with mile markers, set your ODO to 0 and compare mile markers to your odometer. Not hard to verify.

Hope this is the correct trend. If not, I apologize.
I was looking to find the correct size for my 2017 GS 350 f sport AWD . Just to make sure:
19"x8" with a tire size of 235/40R19 and the wheel bolt pattern is 5x114.3???????
I am thinking to replace them with same size Vossen VFS-2 gloss graphite but apparently they are not making them in 19X8. I am listening to you guys since some have more knowledge then me. I don't really want to run into a problem since for sure Lex engineers put the 19x8 as the best option for the wheels.
Any recommendation please? Thank you in advance.

yes our cars are 5x114.3 bolt pattern.
there is room to go bigger such as 19x9 but offset is also part of the equation.
lexus puts the stock wheel size as a global standard but we don't have to strictly stick to that script!

case in point, you can check out the wheel thread here for more insight to sizing, offset, and tire sizing.

Thank you for your answer.
I did read that thread but couldn't find nothing about square with a 2017 Lex GS 350 F Sport. Everyone wants bigger whell on the back ... I know I can go with a 20X9 but what I don't know is what the min offset is in order to pass the rotor.
