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.

“It’s always low on air, I was putting maybe 5-8 psi in there every few days but I couldn’t find a leak/nail/hole in the tire.”source ↗

“Mazda confirmed they also could not find a hole in the tire.”source ↗

“Now- and yes it’s getting colder- I’m putting 10-15 psi in my tire DAILY. I still cannot find a hole but I don’t know what else could be wrong.”source ↗
