Tire Pressure and TPMS
I am the new owner of a 2005 Shinka and so far I'm loving it. Huge upgrade from the old rusty pickup. I have had the car for less than 2 weeks now and I have noticed the TPMS light has come on a few times. It seems to go off either after the tires warm up or the next time I drive the car. So my questions are as follows.
What is the pressure most people are running with the stock Tires / Rims? The book says 32PSI yet the tire says max 51 PSI?
At what pressure does the TPMS system get activated? I checked my tires and they were all betwen 29 and 31. Is this too low?
Thanks for the help.
Mike

If you check your pressures after the tires have warmed up, then they're about 2 lbs higher than cold. Check them first thing in the morning before you drive the car; 29 warm means about 27 cold which is low enough to set off a sensor. Set them all at 32 cold and you'll be fine.

always run what the manual recommends for tire pressure for street driving, Mazda recommends this pressure for the best combination of ride and handling for street driving.
the 'MAX' tire pressure on the tire sidewall means the maximum tire pressure the tire can be SAFELY used in, it DOES NOT MEAN FILL IT TO THE MAX!!!!!
and IIRC, the TPMS will not go off between 26psi and 40psi...
was it cold mornings when you have the TPMS light turn on? I had that happen to me on one cold winter morning (i think it was the first 'cold' day toward the end of fall), turns out it got cold enough that my tires only had 25psi

From what I've been told (by someone who's read the TPMS setup instructions), the TPMS sensors are designed to accept 32psi +/- 4 psi. This means that the tire pressure warning indicator will light if the tires are greater than 36 psi and if they are less than 28 psi. As pointed out in the earlier posts. You want to check and set your tire pressure with cold tires. From my experience these bounds make sense.
