FAQs

What does 'RunFlat' technology mean?

RunFlat technology allows the tyre to continue rolling for a limited distance (e.g., 80 km) at a reduced speed (e.g., 80 km/h) even after a complete loss of air pressure. This provides safety and convenience, enabling you to reach a service station without immediate roadside assistance.

How do I know if my tyre has a puncture when using RunFlat technology?

Most vehicles equipped with RunFlat tyres also have a Tyre Pressure Monitoring System (TPMS) that will alert you when a tyre has lost pressure. Visually, a RunFlat tyre may not appear significantly deflated.

Can a RunFlat tyre be repaired?

Whether a RunFlat tyre can be repaired after a puncture depends on the type of damage and the tyre manufacturer's guidelines. Some damage may not be repairable, and the tyre may need replacement. Always consult a professional tyre service centre.

What is the difference between this tyre and a standard tyre?

The primary difference is the reinforced sidewall construction of the RunFlat tyre, which supports the vehicle's weight when deflated. This can sometimes lead to a firmer ride compared to standard tyres.

What does the '91V' rating mean?

The '91' is the load index, indicating the tyre can support a maximum load of 615 kg. The 'V' is the speed rating, indicating the tyre is approved for speeds up to 240 km/h (149 mph).

Do I need a special type of wheel for RunFlat tyres?

While RunFlat tyres are designed to work with standard wheels, some manufacturers recommend specific rim designs for optimal performance and safety, especially regarding bead seating. Consult your vehicle or wheel manufacturer's specifications.

How should I maintain the KUSTONE Quiet Q7 RunFlat tyre?

Maintain correct tyre pressures as recommended by your vehicle manufacturer, inspect for wear and damage regularly, and seek professional advice if you experience any issues or after using the RunFlat capability.

Troubleshooting

Tyre pressure warning light is on

Check tyre pressures immediately using a gauge. If a specific tyre is low, it may be punctured. Follow the RunFlat procedure if necessary and get the tyre inspected by a professional.

Unusual noise or vibration

This could indicate uneven wear, imbalance, or internal tyre damage. Have the tyre inspected by a qualified technician.

Reduced ride comfort

RunFlat tyres can offer a firmer ride. Ensure tyre pressures are set to the manufacturer's recommendations. Significant discomfort may warrant a professional inspection.

Tyre appears deflated but is still drivable

This is the intended function of RunFlat technology. Drive cautiously at reduced speed to a safe location or service centre and have the tyre inspected and repaired or replaced.

Setup, Compatibility & Care

Setup:

This tyre is designed to be fitted by a professional tyre service centre. Ensure the wheel rim is clean and compatible with RunFlat tyre specifications. Proper inflation to the vehicle manufacturer's recommended pressure is crucial for optimal performance and safety.

Compatibility:

The KUSTONE Quiet Q7 in size 205/55 R16 91V is compatible with vehicles that specify this tyre size and type. Crucially, vehicles equipped with RunFlat tyres often require Tyre Pressure Monitoring Systems (TPMS) to alert the driver to a loss of pressure, as the tyre may not appear deflated.

Care:

  • Regularly check tyre pressure using a reliable gauge. A TPMS is highly recommended.
  • Inspect tyres for any signs of wear, damage, or embedded objects during routine checks.
  • Avoid aggressive driving, such as harsh braking or rapid acceleration, which can increase wear.
  • If a puncture occurs and the RunFlat capability is used, adhere strictly to the speed and distance limitations and seek professional inspection immediately.
