I purchased a 2013 Volt today. My wife has had her 2015 for about a month. Love it so far. It is the Premium package, so it has more bells and whistles than my wife's.
Right, and 2011's actually said 35psi, but most people on here would agree that these "recommended" values are more like minimum values. 40-45psi is a good range.I owned a 12 and 13 and the answer is 38 PSI COLD for BOTH cars. Can verify by looking at the label on the drivers door frame.
I'd refresh the app.
