Yesterday added SO3's all around and now have low air alert blinking incessantly.

Actual pressure up front [225/45R18]: 32-33
Digital reading: 28-29
Actual pressure in rear [245/45R18]: 34-35
Digital reading: 29-30

Air pressure was measured 3 ways and they all read about the same [2 readings mechanical, 1 reading digital]. When the tires heated up a bit, each reading went up 2 pounds.

Is this normal?

 

You have to get the PSI up over 35 for the warning light to go out. Trust me. Do this and drive around for a bit and your problem should go away.

 

Question on tire pressure monitor. The brochure of the Z says it is "real time." I am assuming they put a device inside the tires attached to the wheel to take that measurement.

1- Is this correct?

2- If you change wheels, and order them online, they come fitted and balanced; what one would do to keep the tire pressure monitor?

Thanks in advance,

 

 

Thanks, I'll give this a go.
