tire pressure

[2007SunLight3]

hi, i was wondering about the tire moniter senoring in the 07 mazda 3, whats the low or whats the pressure that will make it go off, mine went off the other day and it said 31, and the car info on the door says put in 32,
at what point/pressure will trigger it to go off

just remember its getting colder and every 10 deg is 1 psi loss. mine has been going off in the morning.

2 psi difference will set off the tpms light (direct from mazda service manager)

what psi will trigger it,

 

[jbiird317]

2 psi difference from the spec. So if the door says 32, then it should be anything less than or equal to 30 would set it off

i was going to say ive seen it go off when i was at 2 under in the front but now we know.

It's not psi off the stated numbers. It's when the tire pressure drops since the last tpms update.

everytime i go to my dealer for service, they set the pressure in all my tires to 30lbs. So now i have a 3rd item to remind them to ignore... 1) no test drive after the service. 2) no wash
3) leave my tire pressure alone

and i've had it with 46 dollar oil changes, too. I don't mind them making a profit but that's over the top.

I just hand them 7 quarts of Mobil 1, and they charge me $23 bucks labor.

I've been thinking about going to nitrogen.
