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...

 

I use 36psi front, and 38 psi rear (cold) with the stock tires

 

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.

 

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

 

Curious question. How do you guys fill up your tires? At a gas station? Man my tires (cold) are at like 29/30 right now. I need to put some air ASAP.

 

Specs for here 35 psi for front and 38 psi for rear.

 

i go 38 psi for all tires.

 

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).

 

yeah man. QT Or racetrac offer free air for individuals. so whenever i need to pump air! that's the spot haha

 

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.
