What's a regular tire pressure for yalls 3IS, it's been gettinh cold down here in Texas and my tire pressure been going down to 30-31. So I pumped it back up and now it's reading 40...
36 all around, when cold (not driven in a few hours). This will require adjustment with the weather. the tires can easily reach 40 with highway driving. That's normal, and meaningless. Need to check when cool.
The factory recommended cold tire pressures are indicated on a label in the driver's door frame (or on the side of the door, depending on the market).

In the past decade or so, gas stations are started charging for compressor air so I've since purchased a small compressor for home use (110V, not the dinky 12V ones).
stock setting is 36, but once you drive it for a bit, they warm up and I have seen it gone to 40-41 which is normal i believe.. my car is AWD
thanks! yeah when i start up my car after a long cold night. its around 35-36 PSI. Then when i start to drive around it rises to about 39-40 psi. thought i was the only one.
I measure my AWD IS at 36 psi cold with my own pressure gauge. I found that the pressure sensors are a little bit off from each other, which is why I use my own gauge to be consistent.
