HOW TO PROPERLY CHECK YOUR TIRE PRESSURE
According to the National Highway Traffic Safety Administration (NHTSA) on tire-related crashes, the leading cause of tire blowouts is under-inflation. Aside for the potential for car accidents, under-inflation can cause negative effects on your vehicle’s handling and can reduce the overall life of your tires. Additionally, under-inflation increases the stress on your tires leading to tread separation and tread wear.
In order to protect your tires from under and over-inflation you can follow these air pressure tips:
AIR PRESSURE TIPS
Follow Manufacturer Guidelines
If you’re unsure what the recommended tire inflation pressure for your tires are, you can locate recommended pressures as follows:
• On the vehicle information sticker that can often be found on the driver's door jamb
• A label located on the glove compartment door
• Printed in the vehicle owners manual
Keep in mind that the inflation pressure shown on the tire’s sidewall displays the maximum pressure, which is based on the tire’s maximum load capacity. It is best to use the recommended pressure located on the above recommendations, which is based on the normal load of a passenger vehicle. If you are unsure of the recommended pressure, or cannot locate the information, it is best to your local mechanic.
Valves and Valve Caps
Valves on your tires must be free from cracks as a deteriorated valve can cause air to escape from your tires. If you purchase new tires or notice a cracked or missing valve, replace all tire valves to avoid tire pressure loss. Valve caps must be tightly closed to prevent the valve from leaking.
Check Pressure & Adjust Once a Month
Tires lose on average 1 psi, per month. Keeping this rate in mind, it is important to check tire pressure at least once a month or before long road trips.
Check Spare Tire Pressure
Check your air pressure on your spare regularly, as your spare could also lose tire pressure with time. Avoid being stranded and having to pay for a tow truck.
Check Tires Cold
Check your air pressure when your tires are cold as tires become hot after driving. This is best done before you’ve driven over a mile or when your car has been parked for at least three hours. Keep in mind that air pressure goes up in warm weather and down in cold weather.
Keep a Tire Pressure Gauge
Purchase a quality tire pressure gauge and check it for accuracy with your local mechanic. Keep the gauge in your glove compartment and test it periodically to ensure it is reading accurately.
