Keeping your tire inflation pressure at its optimal level is highly recommended because it preserves the life of your tires. It also gives you better mileage because under- or over-inflated tires cause the car to move more slowly, thus needing more fuel to get it moving.
- Tire Pressure Gauge
- Tire/Car Manual
- Air Compressor
Step 1: Determine the Correct Pressure
Get your car’s manual or tire’s manual in order to determine the recommended tire pressure. Sometimes, the optimal tire pressure is also printed on the sidewalls of the tire, so you might want to check that out as well.
Step 2: Insert the Pressure Gauge
Find the valve stem and unscrew the cap covering it. Insert the pressure gauge and it should immediately give you a reading of your tire’s current pressure. You can now determine whether it is under or over-inflated.
Step 3: Adjusting Tire Pressure
If your tire is under-inflated, get an air compressor (most gas stations have them for use) and fill the tire with air. If it is over-inflated, press the nipple on the valve stem to release some air pressure.
Step 4: Re-checking Tire Inflation Pressure
Insert the gauge again and check if it has achieved the correct tire pressure. If not, repeat Steps 3 and 4 until the optimal tire inflation pressure is achieved.
