Okay, I want to nail this down. I have the small display and from what I understand you can see the tire pressure on the 4 tires in the large display? I cannot find information on whether it's available on any of the displays in my car at all. My cars since 2015 have had this feature. I guess Lexus is dumbing it down? All you need to know is that one of your tires is low? I know you can get it in the app, but the app is only free for a couple of years and then what? Not that big a deal, I always have a good tire pressure gauge in the car anyway, but it's a disappointment. Someone tell me I'm wrong...
<end rant>

 

I have the 10" screen and I can access tire pressures. Can't remember where it is but I'll look tomorrow if nobody else gives feedback.

 

You have to press the little "car" icon on the left side menu of the main Lexus interface. It is one of the vehicle status displays (fuel economy trip and history, tire pressures, AWD status, settings, etc). If you click on it and it takes you directly to the fuel economy screens, you have to go up to the little "breadcrumb" menu at the top and back out of that screen to see the other screen choices.

 

Whew, thank you! I thought I was going crazy. Here is where I went wrong - there is another "Tire Pressure" screen where you register a second set of tires etc. I was poking around in there and could not figure out where the actual Tire Pressures were!
