Current trend is to use Nitrogen inside the tires. More dense than regular air so pressures are more stable. But if you check your tires often you will be ok with good old fashioned air. The Tire plackard on the door jamb (some times under the console lid) is cold tire pressure. So add 3 or 4 psi after you drive and the tires warm up. Also there is a owners hand book section 8 page 39 all the way to page 50 continues to tell you about tire grades and DOT numbers and general information about tires. Depending on your car tires size Altima's use 29 to 35 psi cold pressures.
To get the most relevant tire pressure, you need to check when the tires are cool, just before you head out for the day, or hours after your vehicle has been idle. Tires that have been used recently will have a higher pressure due to the heat from use.1  Get a cheap tire pressure gauge from any local auto parts store or hardware store. 2  EVERYONE who owns a vehicle should have one. 3  Screw the cap off of your tire. 4  Apply the tire pressure gauge to get the tire pressure. If they do, go elsewhere. 2  Inflate your tires to the recommended levels. 3  I always go 2-3 PSI over because I have driven to fill the tires and they are hot from use. 4  If you go too much over, deflate the tires by tilting the valve stem until you hear the sound of air escaping the tire.
