Ensuring your tires are full to the Correct energy is an extensive articulation of maintaining a Nissan Maxima. Nissan has designed the tires to operate within certain limits for peak handling and gas mileage efficiency. Luckily, checking the air pressure in the tires of your Maxima is not difficult.
1. Remove the caps from your valve stems. This is easy. Just twist them counterclockwise. Keep these in a safe place so you don't lose them.
2. Cool your car down. Remember, heat makes gases expand, and warm tires will have artificially inflated pressure readings. For best results, take the pressure first thing in the morning.
3. Procure a tire pressure gauge. If you don't already have one, take a look at the selection in an auto parts store. You have to decide whether you want one with a dial readout or pressure stick.
4. Depress the air pressure gauge onto each of your tires. You should press hard enough and at the right angle to stop the hissing sound that means air is escaping. Take note of the results so you don't forget which tires need adjustment.
5. Look at the current air pressure levels in your Maxima and compare those figures with the levels recommended by Nissan. For the Maxima, Nissan states that levels between 26 and 34 psi are best.
