My dart's recommends 34 psi on the driver side sticker. About a month ago the tire pressure light turned on and I bought one of those pencil tire gauges to check it. At the time I had no idea that the pressure rises when the tires are hot, so when I checked it it seemed fine at 34 psi. I though the sensor was busted and kept driving around, I even drive to vegas which is 396 miles one way. I just checked the tires again today when they were cold and they were all at about 30 psi. Is that low enough that I may have damaged the tires given that I drove for over 1000 miles?
