What Are Runflat Tyres?

Safety, convenience, and peace of mind — even after a puncture.

Runflat tyres (also known as RFT tyres, zero pressure tyres, or self-supporting tyres) are designed to keep you moving safely even after a sudden loss of air pressure.

You may also see them referred to as:
Run flat, puncture-proof tyres, Extended Mobility Tyres (EMT), Zero Pressure (ZP), Self-Supporting Tyres (SST), Run On Flat (ROF), or BSR tyres.

This innovative technology has been fitted for years on sport and premium vehicles, offering drivers an added layer of safety and control when faced with a puncture.

Let’s explore how they work, their advantages, and when they’re the right choice for your vehicle.


⚙️ How Do Runflat Tyres Work?

Runflat tyres are built with reinforced sidewalls that can temporarily support the vehicle’s weight even after a complete loss of air pressure.

This means you can continue driving for a short distance rather than being stranded at the roadside waiting for assistance.

Typically, MICHELIN runflat tyres allow you to drive for up to 80 km at speeds of up to 80 km/h after a puncture — enough to safely reach the nearest garage or tyre service centre.

In essence, runflat technology provides extended mobility after a puncture, keeping you in control and out of harm’s way.


🔍 How to Recognise Runflat Tyres

Runflat tyres are easy to identify by checking the markings on the tyre sidewall.

Each tyre manufacturer uses specific codes, and for MICHELIN, you’ll find:

  • ZPZero Pressure

  • EMTExtended Mobility Tyre

These markings indicate that your tyres are designed with self-supporting sidewalls for continued use after deflation.

Always remember: while runflat tyres allow you to keep driving after a puncture, you must still visit a tyre professional promptly to have the tyre inspected or replaced.


🛞 What to Do in Case of Pressure Loss

If one of your runflat tyres loses pressure:

  • Keep calm and maintain a moderate speed.

  • You can continue driving up to 80 km at a maximum of 80 km/h, depending on load, temperature, and road conditions.

  • Avoid long distances or high speeds, as prolonged driving on a deflated tyre can cause irreparable damage.


🔧 Are Runflat Tyres Repairable?

Runflat tyres can sometimes be repaired, but it depends on the tyre’s condition and manufacturer’s policy.

For MICHELIN ZP (Zero Pressure) tyres:

  • Repairs are possible only once, and only by a qualified professional.

  • The repair process follows the same inspection standards as for non-ZP tyres.

  • Some tyres with specific sidewall markings may not be repairable, so always consult your dealer or tyre specialist.

✅ Always have a professional assess the tyre before attempting any repair.


🧰 Can Runflat Tyres Be Fitted at Home?

While technically possible, fitting or removing runflat tyres at home is not recommended.
Their reinforced structure makes mounting more difficult, and incorrect fitting can lead to safety issues.

Instead, visit a certified tyre dealer or Michelin-approved service centre for proper installation using the correct tools and procedures.

If your spare tyre is a runflat, it can be replaced the same way as a regular tyre.


🛡️ Advantages of Runflat Tyres

1. Safety

  • Maintain control even after a puncture.

  • Reduced risk of the tyre coming off the rim.

  • Avoid stopping in dangerous or high-traffic areas to change a tyre.

2. Comfort

  • No need for immediate roadside replacement — you can drive up to 80 km at reduced speed.

  • Save trunk space (no need for a spare wheel).

  • Reduced vehicle weight for improved efficiency.

3. Savings

  • Eliminate the need to buy and carry a spare tyre or repair tools.

  • Lower long-term maintenance costs.


🚗 Can My Vehicle Be Fitted with Runflat Tyres?

Runflat tyres are only compatible with vehicles specifically designed to use them.
Before fitting, make sure your car meets the following conditions:

  1. Double-hump rims — designed to keep the tyre securely in place when deflated.

  2. Vehicle manufacturer approval — your car must be approved for runflat use, either as standard equipment or as an option.

  3. Tyre Pressure Monitoring System (TPMS) — this system alerts you immediately if pressure drops, a critical feature for runflat performance.

⚠️ Michelin does not recommend fitting runflat tyres on vehicles not originally designed for them.

For best performance, Michelin also advises fitting four MICHELIN ZP tyres to maintain consistent handling and stability.
