Thanks for that reminder. I admit to not having read the fine print, but the small print on these tire websites states that if you have staggered fitment, it's 50% of the mileage warranty, not necessarily entirely voided. But I could definitely be misinformed here.

 

That's correct basically i'm saying that you can go square setup on staggered wheels.

The front wheels on the F Sport are 19x8, the rears are 19x9. A tire that is 235/40/19 or 245/40/19 will fit any wheel that is 19" in diameter and anywhere from 8.0 to 9.5 inches wide. The tires in the rear may be stretched just a little to accommodate the wider width, but this does not affect safety or performance of the tire as long is its within spec.

This will allow you to keep your existing OEM Lexus F Sport staggered wheels, but buy the same tire size / tire brand for all 4 and likely have a longer life expectancy. Sorry for any confusion and hope I cleared it up!

 

That's great news, thanks! I will plan to do the Pirelli's Cinturatos all around in that case. Anyone have insight on pros/cons of going 235 vs. 245 all around? Looks, performance, gas mileage, rubbing, etc?

 

same question here. I think tire rotations will still be a challenge unless someone is willing to un-install / re-install the tires each time

 

From what I've gathered here, I "think" the answer is no tire rotations. But at least you can get the same tires on all 4 wheels, even if they wheels are staggered. That is the benefit. But someone please correct if that is not right.

 

Hoping this is my last question, sorry everyone. But thanks for all the advice. I am going to go with the Pirellis. The only question now is the size.

Option 1: 235/40/19 all the way around
Option 2: 245/40/19 all the way around
Option 3: 235/40/19 up front and 245/40/19 in the rear

Thoughts? Thank you!

 

You're right: rotation will not work as the rear will be stretched a little bit to accommodate the wider rear wheels.

If it was me, i'd go with the 245/40/19 all around. The 245 width will accommodate your OEM F Sport 19x8 wheels up front perfectly, and will cover the OEM F Sport 19x9 wheels in the rear well enough that you will likely be unable to tell there is any difference.

Post pics when you get 'em set up!

 

Dang, wish I knew that before buying the 275 rear. Oh well.
I still get the traction light when gassing it, even with those tires
