What are Runflat Tyres?

The majority of the time, when a puncture or loss of tyre pressure happens, drivers get frantic and try to acquire a new tyre as quickly as they can. Runflat tyres are exactly what they sound like; they allow you to continue driving even when the pressure in your tyres is low. Generally speaking, you may drive up to 50 miles per hour at 50 mph before needing to change your tyre or have a puncture fixed, however this can vary depending on the model of tyre and the weight of the vehicle you are operating.

Only more recent vehicles with a built-in TPMS (Tyre Pressure Monitoring System) that will detect any changes in tyre pressure and inform the driver should be installed with runflat tyres.

How Do Runflat Tyres Function?

Runflat tyres are actually fairly simple to understand scientifically. They have a reinforced sidewall that was expressly designed to serve as an additional defense against wear and strain. Additionally, this sidewall is made to carry additional weight without harming the wheels.

How to Detect Runflat Tyres

By looking at the markings on the sidewall of your tyre, you can quickly identify runflat tyres. The majority of tyre manufacturers have their own run flat marks even though there is no universal code to denote run flat capability. The top-selling premium runflat tyres manufacturers are listed here, along with the symbols they use to designate run flats.

  • Bridgestone – ROF, RFT, RSC
  • Michelin – ZP
  • Pirelli – RSC
  • Dunlop – DSST, ROF
  • Goodyear – ROF, EMT
  • Continental – SSR

Are My Runflat Tyres Repairable?

On runflat tyres, damage is not likely to occur, but it can occasionally be prevented. On the other hand, we would never advocate fixing a broken run flat. The strength, durability, and safety of these tyres will be greatly diminished if the sidewall has been damaged.

One of the primary reasons it is discouraged is that a fitter or garage will not be able to determine how best to replace a deflated or damaged tyre if it has been driven on for any length of time or at any speed. Due to this, the majority of fitters will advise replacing your run flat rather than even offering to fix it.

As a best practice, we advise changing the tyre as soon as you discover a puncture, damage, or your TPMS system has warned you that the pressure in the tyre has dropped.

How Long Can a Punctured Runflat Tyre Be Driven On?

You can’t keep using a runflat tyre after it develops a puncture. Typically, you can continue driving at 30 mph for another 50 miles. There is enough time to get to the closest garage and have new tyres installed. The precise range relies on factors including your driving speed, your vehicle’s load, and the road’s circumstances.

The Advantages of Runflat Tyres

When driving in hazardous or uncomfortable conditions, you don’t have to change your tyres. This is one of the advantages of run-flat tyres and may perhaps be their greatest advantage. With traditional tyres, a flat requires immediate replacement or towing of your vehicle.

Runflat tyres are more stable than regular tyres in a puncture condition. Runflat tyres can assist you in maintaining greater control in a total air loss condition than normal tyres since they are designed to sustain your car even when they have no air.

The demand for RFT tyres is anticipated to rise as long as people prioritize safety among the attributes they seek in a car. It could only be a matter of time until RFT tyres start to replace conventional tyres as the standard rather than the exception in new cars due to its dependability with linked technologies like TPMS.
