What Causes a Flat Tyre? Prevention Tips for London Drivers

1. Nails and Road Debris — Most Common

Nails, screws and glass from London's busy streets and construction zones embed in the tyre tread and slowly release air. Prevention: Inspect tyres regularly and avoid driving through debris where safe to do so. Catching embedded objects early prevents a slow puncture becoming a roadside emergency.

2. Potholes — London's Biggest Tyre Killer

A sharp-edged pothole pinches the tyre between the rim and the road, causing instant deflation or invisible internal damage that leads to a blowout later. Prevention: Maintain correct tyre pressure — underinflated tyres are far more vulnerable to pothole damage. Avoid potholes where it is safe to do so.

3. Kerb Strikes

Driving over or scraping kerbs in tight London streets damages the tyre sidewall. Sidewall damage is unrepairable and requires immediate replacement. Prevention: Slow right down over kerbs when entering driveways. Take care when parking parallel on narrow streets.

4. Valve Stem Failure

The rubber valve stem degrades over time, cracking and allowing slow air loss. Prevention: Replace rubber valve stems when fitting new tyres. Keep valve caps on at all times.

5. Tyre Age and Degradation

Old tyres develop micro-cracks even with adequate tread, weakening the structure unexpectedly. Prevention: Replace tyres over 5 years old regardless of appearance.

6. Underinflation

Consistently low pressure causes heat build-up that weakens tyre structure, leading to blowout. Prevention: Check pressure monthly when cold.
