Bought G37 wheels for my 04 sedan and took my TPMS out of my 17" stocks for the new wheels - put my 17s back on and the TPMS has not gone off (TPMS warning)..I thought for sure it would have gone off by now, prob drove 30-40k since taken out - anybody know why this would happen???

and as far as I know there working cauz had a flat 2 mnths ago..

 

It will only come one after 30 - 40 miles of continuous driving and resets every time you turn the car off. For people driving less mileage one way trips daily the system is worthless. I've been without TPMS sensors installed for 6 months and just saw it for the first time last week. If you get on an interstate and drive for 40 miles you'll see it.
