How to Check Tire Pressure
Checking tire pressure is an important part of maintaining a vehicle’s safety and performance. Properly inflated tires can improve fuel efficiency, extend tire life, and
enhance handling and braking. Here are some steps to check tire pressure accurately.Using a Tire Pressure Gauge
The most accurate way to check tire pressure is to use a tire pressure gauge. Here are the steps:
- Start with cold tires if possible: Vehicle manufacturers specify PSI (pounds per square inch) of pressure assuming tires are cold. Tires are considered cold when the vehicle has been parked for three hours or more or if the vehicle has been driven less than a mile at moderate speed.
- Remove the valve cap: Remove the screw-on cap from the valve stem (these caps are often missing on older tires) and press the gauge’s fitting on the valve stem in a single, firm motion.
- Get an accurate reading: The tire pressure will be displayed on the gauge. If the reading is below the recommended PSI, add air to the tire until it reaches the correct pressure. If the reading is above the recommended PSI, let air out of the tire until it reaches the correct pressure.
- Replace the valve cap: Replace the screw-on cap on the valve stem to keep out dirt and moisture.
Understanding the TPMS
Many modern vehicles come equipped with a Tire Pressure Monitoring System (TPMS) that alerts the driver when tire pressure is low. Here are some things to keep in mind when using TPMS:
- Use TPMS as a backup: While TPMS can be a helpful tool, it is not as accurate as using a tire pressure gauge. It is still important to check tire pressure regularly with a gauge.
- Understand the warning light: If the TPMS warning light comes on, it means that one or more tires are significantly underinflated. Check the tire pressure with a gauge and add air as needed.
- Know the limitations: TPMS can only detect low tire pressure, not overinflation. It also cannot detect a puncture or other damage to the tire.
By following these steps, drivers can ensure that their tires are properly inflated and their vehicles are safe and efficient.
