A case study from the National Highway Traffic Safety Administration showed that many drivers overlook these minor damages, resulting in unsafe driving conditions. -
Valve Stem Problems:
Valve stem problems often occur due to wear or damage. The valve stem allows air to enter and exit the tire. If it cracks or becomes loose, it can leak air slowly. According to the Tire and Rubber Association, worn valve stems account for a significant percentage of tire pressure loss. Regular inspections can help identify these issues before they escalate. -
Rim Damage or Corrosion:
Rim damage or corrosion can cause slow air loss from the tire. Corrosion on the rim surface can prevent a proper seal between the tire and the rim. This issue can be exacerbated by harsh road conditions or exposure to road salts. A study published by the Journal of Transportation Engineering indicated that rim corrosion significantly contributes to tire failures and leaks over time. -
Temperature Changes:
Temperature changes can lead to fluctuations in tire pressure. When the temperature drops, air inside the tire contracts, reducing pressure. Conversely, rising temperatures can expand the air, causing over-inflation. The American Society for Testing and Materials advises maintaining proper tire pressure year-round, as every 10°F change can affect tire pressure by approximately 1 psi. -
Aging or Wear of the Tire:
Aging or wear of the tire can naturally lead to a slow leak. Tires deteriorate due to exposure to UV light, ozone, and wear from road usage.
