I know that tire pressure can fluctuate in extreme temp changes, but every so often, i get a low tire pressure warning after my car sits overnight or while I'm at work. However, after driving for a few minutes, the tire pressure reading slowly increases in each of the tires. For example, when i got out of work tonight, the tire pressure was 31 in front tires and 32 in rear tires...by the time that i got home (15 mins later), it read 35 in the front and 36 in the rear.

Anybody else experience this?

this is normal. your tires get warm/hot over time it gets higher. for example, if you park your car one side facing the sun and the other side away from the sun.... the side facing the sun, your tires will be high in psi than the ones on the other (hope it makes sense)

ITS NORMAL.....

The recommended pressure is 36. Is it for cold measure(before you drive you car)?

Yes. always fill up when the tire is at its coolest period (different for each seasons) to 36
