I have a 05 g35c and on my way to work this morning I got the tire pressure monitoring light. I'm going to check the pressure when I leave though they do not appear low. So my question is what else could be causing this and secondly what pressure should oem 19" rays have in them? Thanks!

 

I have mine set at 35psi all around.

 

was it cold in the morning? that happened to me a couple times when the warning light would come on cause of the cold air in the morning. after driving it a little bit, it would go away. but as a precaution i still went and filled up to 35psi all around.

 

mine came on a few days ago, i picked up a nail on the road somewhere and had a slow leak, just filled it up to 35 everyday till i had time to get it patched. all is good now

 

Well I stopped and checked all the tires and the right rear was down to around 27 so I filled it up to around 37 and the light went off. Seems I may have a slow leak in that tire so I will have to keep an eye on it. Thanks for the help!

 

if the light comes on again, have it checked out cause its probably a nail. keep the nail in there until you take it in though, otherwise it will leak much faster

 

light comes on if it falls below 30 psi
