So you’ve switched out the rears for 19 X 8’s? I’ve thought of that to be able to rotate tires. Is that a problem with the suspension camber etc?

Appreciate it, that's very helpful information. I have the 18" wheels and the 245s are each 2lbs heavier than the 235s. Since there is no performance need or benefit from the larger tire (especially with the PS4S compound) I am trying to see if the slight aesthetic bonus is worth it.
As far as the 2 pounds? So every tire in the same size is Not exactly the same size as you would think. From tire type and manufacture Brand to manufacture the weight, height and width is not exactly the same. There are slight differences. Performance wise, I do not personally like to reduce any drivetrain ratios or drivetrain weight ratios. If there is a increase I like to have a modified increase to pull it myself. If its increase drive or weight it leads to more, if I can modify to pull the increase if better than stock. Just my personal desires.

To me the 245/45/18 actually handled better. Especially for grip from a start in the wet and or any surface that was not free of debris. The ride was better too, not a jolty and bumpy. The other thing I liked was that it slowed the odometer down racking up miles a bit, with the speedo actually matching more accurate on the ES as it was off with the stock tire size.

The 245 vs. 235 weight and dimensions were compared using Tire Rack's measurement of diameter, section width and tread width. The height difference is 1.5% which should only throw off the speedometer by 1mph. Yes torque to the ground would reduce by 1.5% but I would be able to get an additional 1mph out of each gear so at some point, theoretically, staying in that higher gear ratio may benefit to faster acceleration at a specific speed if I bothered to run the math. Its only 1.5% so likely not within the threshold to notice anything as a human, regardless of what the math may show.
Yup, as you mentioned, the tread width is best indicator of width to compare to different tires of the "same size". Even the same manufacturer can have confusing widths depending on the model. I had a Porsche "N0" spec Michelin Pilot Super Sport that was a 295/40/20 but the tread width was just as wide as a Michelin PSS of PS4S in 315/35/20. The same with the "N0" front tire, the 255 width was just a hair thinner than the regular 285 PSS. The difference was easily seen in the tread width measurement in absolute inches, so its super helpful when Tire Rack displays that for all tires.

I run Pirelli P7 Cinturato All Season Plus 2 with 245/45/18 size tires on stock lux wheels 18 x 8.
I highly recommend the upsized tire for pothole protection and slightly better ride quality. Also note at 80 mph on the instrument cluster your actually going 81 mph. It's not an issue at all otherwise.

Thanks for the input. You said you have only run Pirellis, with the PS4S, there are zero grip issues, I highly recommend those and I will only run those and future evolutions since they are so far ahead of anything else I have used.

Michelin is not what they use too be. They were out extremely fast. Its known consensus of many all over the internet. Also about changing the drive ratio, little lose on top, but you can actually feel the gain up top when they get going. Funny as it is, most other cars like Audi, BMW, and MB run the 245/45/18 on their same size weight cars and their cars handle very well. I always wonder why Lexus choose 235? Must be some reason, but IDK why?
