basically..bout 2 weeks ago it came on..i figured it was nothin i was soon to take it to infiniti for service..anyways.last night it beeped again (the light never came off)...i pull out of my drive way this morning only to hear bumps and see a flat tire...so my question is..does the TPMS go off at stages or just at once cause i think its wierd it beeped right be4 it went flat..i always thought it came on and stayed on with just 1 beep..

oh and tip of the day..TPMS dont lie!

ha

 

My TPMS is lying to me... but I think it's cold air related.

I have had my TPMS beep once and the light stay on until the tires have had air put in, regardless of how many times the car has been shut off.

 

It will come on any time it sees bad tire pressure.

 

When your tire pressure drops below 29 LBS the sensor will sound and show on your dash. If you run 35 PSI like Nissan recommends in your tires I don't believe the weather would have an influence on the sensors. If however your pressure is close to 30 and it's very cold that might set the TPMS warning off. Check your tire pressure at least every month and don't run less than 35 and not more than 37 PSI....best for gas mileage and wear.

If it's cold air related, it's not lying to you... when the air gets cold, your tire pressure actually does go down. Haha.
