Product Information

Full details

The Churchill RCB009 RunFlat XL tyre is designed for drivers seeking enhanced safety and performance, especially during unexpected tire punctures. Its key benefit is the ability to drive for a limited distance at reduced speed after a loss of air pressure, offering peace of mind.

FAQs

What does 'RunFlat XL' mean?

'RunFlat' means the tyre can be driven for a limited distance at a reduced speed even when it has no air pressure. 'XL' stands for 'Extra Load', indicating it has a higher load-carrying capacity than a standard tyre.

Can I fit these tyres to any car?

These tyres are designed for specific vehicle makes and models that use the 225/55 R17 size and are often equipped with TPMS. Always consult your vehicle manufacturer's recommendations before fitting RunFlat tyres.

How far can I drive on a flat RunFlat tyre?

Typically, you can drive up to 50 miles at a maximum speed of 50 mph, but this can vary. Always check the manufacturer's specific guidelines for your tyre model.

Do I need special wheels for RunFlat tyres?

RunFlat tyres are designed to work with standard wheels, but the vehicle needs to be compatible and usually requires a Tire Pressure Monitoring System (TPMS).

Can a RunFlat tyre be repaired?

In some cases, yes, but it depends on the extent of the damage and whether the tyre was driven on extensively while flat. A professional tyre technician must assess the tyre's condition.

What is the load index and speed rating?

The '101' is the load index, indicating the maximum weight the tyre can carry. 'W' is the speed rating, indicating the maximum speed the tyre can sustain. For this tyre, consult a tyre professional or the manufacturer's chart for the specific values.

Troubleshooting

Tyre loses pressure rapidly.

Activate run-flat mode and drive cautiously to a safe location. Have the tyre inspected and repaired or replaced by a professional as soon as possible.

TPMS warning light is on.

Check all tyres for visible deflation. If none are apparent, the TPMS sensor may need recalibration or service. If a tyre is low, proceed with caution to a service center.

Rough or harsh ride.

This can be a characteristic of RunFlat tyres. Ensure the tyre pressures are set correctly according to the vehicle manufacturer's specifications. If the ride is excessively harsh, consult a tire professional to confirm correct fitment and pressure.

Setup, Compatibility & Care

Setup:

  1. Professional Installation: RunFlat tyres must be installed by qualified tire professionals. They require specific mounting and balancing procedures.
  2. TPMS Required: Vehicles fitted with RunFlat tyres usually require a Tire Pressure Monitoring System (TPMS) to alert the driver to a loss of pressure.

Compatibility:

  • The Churchill RCB009 is specifically sized for vehicles that use 225/55 R17 tyres.
  • Confirm your vehicle's manual or existing tyre sidewall for the correct size and load/speed rating (101 W). Not all vehicles are equipped to handle RunFlat tyres; consult your vehicle manufacturer.

Care:

  • Regularly inspect tyres for wear and tear.
  • While designed for run-flat use, it is highly recommended to have any tyre that has been driven on with zero pressure inspected and, if possible, professionally repaired or replaced.
  • Avoid excessive speeds or distances when using the run-flat capability to prevent further damage.
  • Maintain correct tyre pressures as per your vehicle manufacturer's recommendations when the tyre is fully inflated.
