Pirelli run flat tyres are marked with ‘RFT’ on the sidewall — a simple sign that your tyres can keep going even after a puncture. In this guide, we explain what the RFT marking means, how Pirelli’s design differs from other brands, and why choosing run flat tyres could make your drive safer and more convenient.

There are several benefits to run flat tyres that make them a popular option for drivers in the UK. Not only are they reinforced which adds extra stability even after a puncture or blowout, but they ensure that such an incident does not result in a loss of control and potential accident. 

They are, in short, a type of tyre that minimises the risk of accidents and prevents drivers from having to stop a repair a tyre that gets damaged on the road. 

But while all run flat tyres have a common purpose and consistent design attributes, the way they are marked differs from one brand to the next. In this article, we’re looking specifically at Pirelli’s run flat tyres and how to distinguish them.

The Pirelli Run Flat Tyre Indicator

Any tyre in the Pirelli collection which boasts a run flat design, is marked with ‘RFT’.

This acronym is simple: standing for Run Flat Tyre. Pirelli’s own range of run flat tyres are specifically designed to support excellent performance even with a flat tyre – keeping the tyre rotating and the vehicle moving smoothly. This marking is typically found on the sidewall of the tyre and lets the driver know that the tyre needs to be connected to a TPMS for safe driving.

In contrast, some other notable tyre brands use markers like ZP and SSR to indicate their own collection of run flat tyres.

Are There Any Visible Signs of a Run Flat Tyre to Look Out For?

Besides the obvious run flat markers as identified above, some other signs that let you know a tyre has a run flat design include:

  • A much thicker sidewall, due to the reinforced design which literally keeps the tyre’s shape when the rubber exterior has deflated
  • Sidewalls which also feel stiffer 
  • Tyres with a more robust shoulder, connecting the sidewall with the outer tread 
  • Connection with a TPMS, which lets the driver know when the tyre has run flat

Run flat tyres may be designed to withstand the sudden loss of air pressure, but that doesn’t mean they can keep the vehicle moving indefinitely. In fact, run flat tyres that have suffered a sudden loss of pressure should be driven more slowly, with the distance capped prior to full tyre repair or replacement.

Do I Need Run Flat Tyres?

Whether you opt for premium Pirelli tyres or choose a cheaper brand, the question remains: are run flat tyres a necessity, or should you opt for standard tyres and keep a spare on board for emergency use?

It really depends on how much storage space you have and whether you want to carry around a spare tyre or be able to keep driving even after a puncture. Run flat tyres are more expensive and have more challenging maintenance needs, but the benefits span performance, convenience, and safety.
