We’ve all been there. You'll be driving along when the check tire pressure light illuminates, or you come out to your car to notice one tire looks a little low. Not everyone has an air compressor in the garage, so they head to the gas station and fill up there. You have to check the door label to see what the correct pressure is before filling up. The air pump either has a digital gauge where you can set the amount of air to put into the tire or a manual one where you have to check the pressure continuously. However, they’re not always reliable and can give erroneous readings. Nissan is trying to uncomplicate filling your tires by taking out the guesswork of when your tires are correctly inflated with its Easy Fill Tire Alert system.
