Just wondering if the full-size spare in my 05 G35x has a TPS monitor in it. I ended up swapping out one of my four wheels with the trunk spare - this was due to an eggheaded rim scraping incident.

I have yet to see a TPS light go on.

Any comments? Thanks.

I'm pretty sure you can tell by the valve stem. The TPS ones have an all metal valve stem while others would most likely be rubber.
