Importance Of Tire Pressure
The Importance of Tire Pressure. According to recent study by the National Transportation and Safety Administration, available at http://www.nhtsa.dot.gov/, more than 25% of all passenger cars and more than 33% of all light trucks have under inflated tires.What does this mean to you?
- Lower gas mileage – Lower tire pressure means lower gas mileage.For each pound of under inflation, your gas mileage can drop up to 1 percent!
- Tire failure – Under inflation is the leading cause of tire failure.
- Faster tread wear – Lower tire pressure also causes the tread to wear out faster and forces premature replacement.
- Poorer handling – The point where the tire meets the road is a crucial element in determining the ride control of your vehicle.Under inflation prevents your ride control system from functioning properly.
- So what is the proper tire pressure for your vehicle?
While there is a lot of information available in the market, the best way to determine this is refer to your owners manual.Each vehicle is designed by the manufacturer with a specific tire and tire pressure in mind.Some things to keep in mind.
- The proper tire pressure is available to you in a number of locations in the owner’s manual or on the door jam or doorpost.Many vehicles now also have sticker on the interior of the gas cap.
- The pressure listed on the exterior of the tire is the maximum pressure that the tire should be inflated to, not necessarily the ideal pressure.
- Always take the tire’s pressure when the tires are cold driven less than one mile.
- Tires will lose about one pound per square inch (PSI) for every 10-degree drop in the temperature.
- Tires will also lose pressure over time about 1 PSI per month.
- To improve the life of your tires, rotate them on a regular basis – every 5,000 to 8,000 miles.Every other oil change is a good rule of thumb.
