Did you know the U.S Department of Energy says that for every 1-psi drop in tire pressure, you can expect your gas mileage to be lower by 0.4 percent. So save yourself some money and check your tire pressure often.
STEP 1 - FIND YOUR VEHICLE'S TIRE PRESSURE NUMBER
To find the tire pressure for your vehicle. Open the driver side door and look for a label near the door latch. Also check the vehicle owner's manual. Do not use the maximum tire psi reading on the tire.
STEP 2 - CHECK YOUR TIRE PRESSURE WITH A DIGITAL TIRE PRESSURE GAUGE
The best time to check tire pressure is in the morning before your drive. Remove the valve cap from the valve stem. Grab your DIYCO digital tire pressure gauge, check your tire pressure and note the reading on the gauge. If the pressure is not within 0.5 psi of the specification, add or remove air as required.
CHECK YOUR TIRE PRESSURE MONTHLY
Remember to check your tire pressure at lease once per month. Over time all tires leak air, so by checking tires regularly and maintaining proper tire pressure, it may improve your vehicle's fuel economy. Which in return pays itself at the pump.
