Tire PSI - order in display?
Sorry guys, I know I have seen a picture of someone explaining the order of the tires PSI display but I spent about 30 minutes searching the forum for "tire pressure" and can't find it. I have a 2010 460 and wondering the order they're listed in. Can someone please detail the order that the tires are listed in - starting from the top?
Also, from reading those threads it seems it's possible to go up about 4-5 PSI as you drive from a cooler climate into warmer climate. Does that sound about right? Thank you.

I don't know your psi order display, but yes I have seen 4-5 psi from cold to hot...especially on a very hot day. Like yesterday I went from 32 in the morning and late that afternoon on a hot day it was 36 on two and 37 on the other two.

Copied from the thread below
What I did is deflated each one to locate which is which, once I knew which is which I had the sensors moved in an order I can remember. Which is from top to bottom- front left (top), front right(2nd from top), rear left(3rd from top), rear right (4th from top) and the Spare on the bottom.

One reason I love this forum is because it occasionally makes me realize I'm not thinking through things correctly... I never thought about the display changing when you rotate tires, etc. Doh! Thanks to everyone for the replies. I'll figure it out manually and keep it logged until the next oil change & tire rotation. Thanks all.

For such a sophisticated flagship car, it is unbelievable that Lexus did not figure out how to include tire position along with the pressure reading. This information is displayed for 2013+ cars. Even for the 2007-2012 cars, this information is probably there in the car's computer somewhere, it's just that their software is not retrieving and displaying it. Wouldn't it be great if Lexus would update their system software on a regular basis (like the WindowsOS and MacOS updates) so that such improvements can be made available in older cars? Do other automakers update their car's system software on a regular basis? It doesn't have to be free, but hopefully not more than a 100 bucks per update.

I would venture to guess that they appear on the dash in the order that each of the sensors was registered with the computer, and that they will remain that way until you rotate tires and that's when the order goes funky. They could just as easily tie the order to the receiver at each corner (I believe this is how it works, please correct me if I'm wrong...) so it remains, I wonder why they didn't.

re-register sensor ids. Display is same as scanning order. I use Autel TPMS tool.

On my previous 2004 Chrysler 300M Special, I could retrain the sensors with a magnet. Anytime I rotated the tires, I was able to reset them through the EVIC which displayed a small vehicle icon with the the pressure listed next to each location. Simple but very useful.

There was no hassle like Lexus. Also look at how Chevy does it using parking light/tail lights, pretty cool.
