Ok so the past week, i notice whenever i start up my car early in the morning, around 8, my tire pressure lights stay up. But than when i was driving for like 30mins it goes off. Than after that, i got out of school and turn my car on again, the tire pressure didn't show throughout that day. The tire pressure warning only go on when it's the first time i start up the car that day. No clue what's wrong, i also notice that the lights goes off on exactly the same road that i drove everyday...anyone can help me out?

 

I would say simple problem, simple fix. Fill the tires to specs, my guess is that when it is cold tire pressure goes down which explains why you have the light on in the morning but when you drive it goes off.

 

iv got that same problem

 

Make sure you set to the proper psi which can be found on a decal on the driver's door jam. The spec is for when its cold. So check em before you drive the car. The rule of thumb is for every 10° Fahrenheit change in air temperature, your tire's inflation pressure will change by about 1 psi (up with higher temperatures and down with lower).
