P460lawd

Newbie, just bought a 2012 ls 460 l awd with 21,000 miles about a month ago- I know, no pictures, just tinted windows and searching for 21" wheels- not putting a remote lowering- keeping it stock. First Lexus we have owned and absolutely can't believe we have it- love it!!! Wife just told me she is getting 5 tire pressure readings on the screen. I told her that is not possible, but she is a car chick and told me where to go!!! Spare is a brand new Michelin 19" on OEM wheel. Trunk equipment ( jack, batteries- cracked me up) never used and I did not pull spare out. How is it possible she is getting 5 tire pressure readings. P. S. Love this site- find myself checking it every nite for info. I'll post picts soon.

Congrats on the new car, 2012 AWD L with low miles sounds terrific! Looking forward to the pics.

The TPMS is monitoring pressure in the spare full size tire also, hence the five pressure readings. Maybe, you get five readings because you have a LWB. In my 2012 SWB car, I was getting TPMS warning but could see only four pressure readings that were all ok. My SA told me it was due to low pressure in the spare, and the warning went away after they filled it.

some versions dont have a spare - instead a 'repair kit' consisting of specially modified pump with foam injector (quick fix, single use).
