Tire Pressure is something, which you shouldn't ignore or delay. Tires are one of the most important components of your car for safety, and comfort. Getting in the habit of checking the tires regularly will help you save time and money.
Tire pressure and regular tire rotations will help you have a comfortable and safe drive. Your tires will last quite a bit longer and you can add air and check pressures yourself.
Open your drivers side door and look for the tag that tells you how much air the manufacturer recommends. This is how much air you should put in your tires, not what is listed on the tires.
Getting in the habit of having your tires rotated about every 6000 miles is a good idea and that way you get the most out of all 4 tires.
