Dolby Digital is the name for audio compression technologies developed by Dolby Laboratories. It was originally named Dolby Stereo Digital until 1994. Except for Dolby TrueHD, the audio compression is lossy. The first use of Dolby Digital was to provide digital sound in cinemas from 35mm film prints.It is now also used for other applications such as HDTV broadcast, DVDs, Blu-ray Discs and game consoles.t was originally named Dolby Stereo Digital until 1994.

One thing that is important for proper driving conditions is proper tire inflation and pressure. The ideal range of pressure in cars is between 193-234 in kPa (kilopascal) or 28 to 34 psi (pounds per square inch). However, in heavier cars, such as minivans, the pressure can be higher, upwards to 303 kPa (44 psi). If a tire is under inflated by 41.4 kPa (6 psi), a loss of handling will be noticed and tire life will decrease. Most notable, fuel economy is reduced by 5%. If over inflated by 41.4 kPa (6 psi), the car will ride harsher since the car is more susceptible to potholes and debris.
i checked the sticker on door it says check manual i cant fine it in the manual i have a 2011 chevy impala ls can someone tell me what the tire pressure suppose to be all of them are at 31 right know. 3 out of 3 people think this is helpful.  I have a 210 Chevy Impala and I just put in 36 psi while the tires where cold and hope it is the right pressure. Just taking a guess and say that the correct tire pressure is between 35 and 40 psi. Anyone know if I'm good to go? Can't find any pressure reading on the tire or on the door jam of the car.
