Why does my tire keep losing air even after getting fixed?

Mechanics often miss slow leaks caused by hidden issues like dirt built up around the rim bead. Taking the car back multiple times without finding the root cause wastes time and leaves you stuck constantly refilling the same flat.

What people tried

Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.

  1. 1
    Taking the wheel off to check for cracks and spray with soapy water
  2. 2
    Over-inflating the tire and submerging it in a water tank to watch for bubbles
  3. 3
    Visiting a different shop and informing them it is the fourth attempt to fix the same leak
  4. 4
    Replacing the rim or valve cap
  5. 5
    Being hypervigilant about tire pressure
  6. 6
    Manually checking and refilling tires frequently

Third visit: "Dirt around the rim bead area where it contacts the tire." He cleaned it. Still leaking at the same rate.source ↗
