Run-flat tyres allow you to continue driving for a limited distance after a puncture, providing peace of mind and convenience. Understanding their technology, benefits, and limitations helps determine if they're right for your vehicle and driving needs.
How run-flat tyres work: Run-flat technology uses reinforced sidewalls that support the vehicle's weight even when the tyre loses air pressure. This allows continued driving at reduced speeds (typically up to 50mph) for limited distances (usually 50 miles) without causing wheel damage.
Types of run-flat technology:
- Self-supporting: Reinforced sidewalls bear the load when deflated
- Support ring: A hard inner ring supports the weight
- Self-sealing: Internal sealant layer automatically seals small punctures
Benefits of run-flat tyres:
- Enhanced safety - no roadside tyre changes in dangerous locations
- Convenience - reach a safe location or tyre centre
- No spare wheel needed - saves boot space and weight
- Maintained vehicle control during pressure loss
- Security - reduced vulnerability when stopped
Limitations to consider:
- Higher initial cost (typically 20-50% more expensive)
- Firmer ride quality due to reinforced construction
- Limited repair options - often require replacement
- Reduced fuel economy due to increased weight
- Not universally available in all sizes
- Require TPMS (Tyre Pressure Monitoring System) to detect deflation
Who should consider run-flat tyres:
- BMW, Mercedes, or other vehicles originally equipped with run-flats
- Drivers frequently travelling long distances
- Urban drivers concerned about roadside safety
- Vehicles without spare wheel space
- High-value vehicles where convenience justifies cost
Maintenance considerations: Run-flat tyres require regular pressure monitoring as they don't show obvious signs of deflation. TPMS is essential for detecting pressure loss early.
Replacement decisions: Some drivers switch from run-flat to conventional tyres for improved comfort and lower costs, whilst adding a spare wheel or repair kit.
