Inflating and maintaining proper tire pressure ensures safer, more comfortable driving and better fuel efficiency. You can improve your gas mileage by keeping your tires inflated to the proper pressure. Particularly in times of high gas prices; in inclement driving conditions such as heavy rain, snow, or ice; and in vehicles of all sizes, tire pressure can make a major difference in driving, wherever you are.
Given the importance of the task, you might think it is complicated, but checking and maintaining your tire pressure is simple, provided you have a good tire air pressure gauge and source of air.
The proper tire pressure for your vehicle is usually found on a sticker in the driver's side door jamb or the glove box and in your owner's manual. Do not use the maximum pressure printed on the tire's sidewall.
