Tyre Valve Stem Leaking on Malaysian Roads: Roadside Help for Singapore Cars | MyMechanic

What to Do Immediately

• Pull over safely, switch on hazard lights, and avoid hard braking or sharp turns.
• Check the side with the low tyre pressure warning and listen near the valve for a hiss.
• If available, top up air modestly to reach a safer spot, without exceeding recommended pressures.
• Call MyMechanic and share symptoms: air loss, recent tyre service, or TPMS valve damage.

Common Causes of Valve Stem Leaks

• A loose or damaged valve core that allows air to seep out.
• A cracked rubber stem from age, heat, or ozone exposure.
• TPMS valve damage from corrosion or cracking.
• Debris under the cap or inside the core preventing a clean seal.

How MyMechanic Helps On-Site

• A safety triage and inspection to confirm the leak's location and tyre condition.
• Quick stabilisations like replacing a valve core or applying a temporary seal.
• A clear decision on towing if the stem is cracked or the tyre is damaged.
• Plain-language updates on findings and next steps.

Prevention and Good Habits

• Replace ageing rubber stems during tyre changes.
• Keep caps on to block dirt and moisture from entering the valve.
• Avoid harsh chemicals on valve areas and rinse gently to prevent corrosion.
