Problem with tire air pressure......
It is a little hot here, and it is wreaking havoc on my air pressure in the tires (Low temp in the 80's, high temp around 114). Please tell me what I should do: (03 coupe, stock tires/wheels)
In the morning when I get it the car, the tire pressure has been as low as 24 psi in all 4 tires. I immediately head to the gas station 3 miles away, and by the time I get there the pressure is at about 28 to 30 psi. I chose not to add air to the tires that read 30. About 2 hours later the pressure in the tires I brought up to 30 at the station was 34psi!
Am I in danger of a blowout due to high pressure, or low pressure? What do I need to do?

You should inflate the tires to 30 PSI when cold (that is when you have not driven on them). You have your tires under inflated. Tire pressure will change with the ambient temperature and when you drive on them due to friction. It is absolutely normal for you air pressure to go up when you drive it. Also you have to be moving for the tire monitor gauges to work correctly. Don't go by your DIC, get a pressure gage.

you can also try reseting the sensors for some reason mine was going crazy after i rotated the tires so i reset them and they work just fine and get the correct readings... i run about 30-32 psi cold with 19/20 wheel combo

Underinflated tires actually caused heat built up and possible tire failure, as well as poor handling and wear. As stated, 30 psi cold, it's normal for the pressure to increase as the tires heat up during driving.

FWIW non RFT's hold pressure better and more consistently...the RFT's seem to fluctuate alot
