Why does my Suzuki Swift frequently lose tire pressure even without a visible puncture?

I’ve noticed that my 2021 Swift’s front left tire often loses pressure over a few days, but theres no nail o r puncture. I drive daily in Karachi. Could this be due to valve leakage, rim issues, o r poor-quality tires?

If a tire is consistently losing pressure without a visible puncture, there are several less obvious causes that are common in Pakistani conditions.

Likely Causes:
Valve stem leakage – rubber valves can crack o r dry out due to heat o r poor quality.

Rim damage o r corrosion – common after hitting potholes o r during rainy seasons.

Poor tire bead sealing – especially with low-quality o r poorly mounted tires.

Tiny sidewall leaks – hard to detect, but possible after curb impacts o r low-pressure driving.

What to Do:
Visit a reputable tire shop to check for slow leaks using a water dunk test.

Replace the valve stem if its old o r cracked.

Ask for rim inspection and cleaning to ensure proper tire bead seating.

Consider switching to better quality tires if repeated leakage occurs.
