Properly inflated tires can help save gas and ensure better handling from your car, so it's important to keep the tire pressure at the optimum amount. Tire pressure gauges are a primary tool used to inspect and measure the pressure of pneumatic wheels or tires so that you can maintain tire pressure in the right conditions. When the tire pressure gauge measures air pressure, the result is usually read at PSI (pounds per square inch). It is recommended that the tire's tires be printed with the PSI level of the tire itself, including the chart inside the driver's door panel. After reading the tire pressure gauge, the number of PSI compared to the tire manufacturer's recommended PSI and compressed air may increase until this ideal pressure has been reached. Inflated tires can result in poor fuel efficiency and increased chances of tire failure. Over-expanded tires can cause dangerous punctures and treatment failures.
Commercial tire pressure gauges come in different forms. One of the most popular types is similar to a ballpoint pen, where one end of the tire pressure gauge has a small opening and is rounded off at the center. This head fits snugly on a standard tire inflation valve. As the user presses the tire pressure gauge valve, some air may escape the tire. This should not affect the actual reading, but it is important to have a good hermetic seal. The pen tire pressure gauge at the other end is a square plastic tube. In this pipe, the pressure calibration mark of the pound is indicated. The air that escapes from the tire valve forces the plastic tube at a predetermined rate. Once the tube stops moving, the user can look at the last visible calibration mark to determine the current PSI level of the tire.
Another type of tire pressure gauge is connected to a commercial air conditioning compressor at a service station. Each valve stem is connected to a compressor hose and the customer can check the PSI reading for each tire for free. A plastic version of the metal tube performs the same measurement, using a spring to return it to the house between the readings. If the tire pressure is low, the customer can activate the coin-operated compressor and add more air. A tire gauge can be used to measure the process at any time.
Keeping the right pneumatic tires is something every driver must learn to do. It is especially important to check your tires before a long trip, in extremely hot weather. Check the air pressure of your spare tires regularly and use pneumatic tires for any other vehicle. Tire pressure gauges will let you know the pressure of your tires, tire pressure gauges, and tire valve connections. This will also inform you if the tire still needs more air or not.
