There are some tyre features built for safety, while others enhance performance, comfort, and the quality of the driving experience. Then there are those tyre features and integrations that somehow bridge all of the above and simply make a tyre better and more premium.
Run-flat integration is one of those features that ticks all the boxes by changing the way a tyre responds to a puncture or damage sustained while driving. Here’s how it works – and how to identify a run-flat tyre by its many potential markings and acronyms.
What is a Run-Flat Tyre?
We’ve all been there; one minute you’re cruising along the motorway or a country lane, and the next minute you’re hit with an almighty bang and suddenly your car wants to veer off to one side. This indicates a puncture or blowout and can stop any journey in its tracks – leaving you either changing the tyre on the side of the road, trying to repair it (if the damage is minor), or calling for roadside assistance.
Fitting run-flat tyres to your vehicle, however, creates a very different outcome.
When a run-flat tyre becomes damaged or suffers a puncture, its reinforced design kicks in – keeping the tyre rotating and allowing the driver to retain full control over their vehicle. Not only does this minimise the risk of an accident, but it also allows the vehicle to continue with its journey.
Of course, there are caveats. Once a tyre has become damaged, the driving style needs to be adjusted – with most run-flat tyres designed to be driven no more than 50 miles at a maximum speed of approximately 50mph. What’s more, it’s integral that any driver considering run-flat tyres has a TPMS built into their vehicle, connecting the tyres with the vehicle dashboard for constant monitoring.
After all, with run-flat tyres created to reduce interruptions to your journey, you need to ensure that you become aware of the damage somehow!
How Do Run-Flat Tyres Work?
Now that we know a little more about the benefits of run-flat tyres and why they are so popular among drivers across the UK, how exactly do they work?
Run-flat tyres are purpose-built with reinforced sidewalls, which can support the weight of the vehicle adequately even after the tyre loses all its air pressure. This sudden reliance on the sidewalls of the tyre can put undue pressure on the tyres, which is why reducing speed and capping the total driving distance is so important.
Because of the need for the TPMS, run-flat tyres can only be fitted to vehicles that enable and support their use. If in doubt, make sure to check the vehicle handbook before fitting run-flat tyres.
