How-To Guide for Checking and Maintaining Proper Tire Pressure

Maintaining proper tire pressure is one of the most critical aspects of tire care. Here’s a step-by-step guide on how to check and maintain the correct tire pressure for your BMW 328i:

  1. Gather Tools: You’ll need a tire pressure gauge, which can be a digital or analog gauge. Many gas stations also have air pumps with built-in gauges.
  2. Check When Cold: Tire pressure should be checked when the tires are cold, as driving can heat up the air inside the tires, leading to inaccurate readings.
  3. Find the Recommended Pressure: Refer to your vehicle’s owner’s manual, the driver’s side door jamb, or the fuel filler door for the manufacturer-recommended tire pressure. This information is typically given in psi (pounds per square inch).
  4. Remove the Valve Cap: Unscrew the valve cap from the tire’s valve stem.
  5. Check Pressure: Insert the pressure gauge into the valve stem and press down firmly to get a reading. Compare the reading to the recommended pressure. If it’s too low, add air until it reaches the correct level. If it’s too high, release some air until it’s within the recommended range.
  6. Repeat for All Tires: Perform this check on all four tires, including the spare if applicable.
  7. Replace Valve Caps: After checking and adjusting the tire pressures, screw the valve caps back on to keep out dirt and moisture.
  8. Regular Checks: Make it a habit to check your tire pressure at least once a month and before long trips. Also, inspect your tires for signs of damage or uneven wear.
