Quick Answer:<\/strong>\u00a0Run-Flat or RFT tyres can operate for short distance after a puncture has caused the tyre to lose air. Also many many modern cars have RFT’s instead of a spare to save weight and improve fuel efficiency.<\/p>\n Most people have heard of run-flat tyres but don’t really know what they are or how they work.<\/p>\n In this blog post, we’ll explain everything you need to know about run-flat tyres, including what they are, how they work, and the advantages and disadvantages of using them.<\/p>\n By the end of this post, you’ll be an expert on run-flat tyres \u2013 and you’ll be able to decide whether they’re the right choice for your vehicle.<\/p>\n We’ll also explain how to get the best possible deals on run-flats from your nearest tyre shop who specialise in fitting run-flat tyres.<\/p>\n Run-flat tyres are a relatively new tyre technology, specially designed by tyre manufacturers so they can continue to be used even after a puncture.<\/p>\n Most punctures will cause loss of\u00a0tyre pressure<\/strong><\/a>\u00a0<\/strong>\u2013 causing a tyre to deflate, but with a run-flat tyre, the tyre is reinforced with special materials and can still be driven on even after it has been punctured. Usually, a run-flat tyre can be driven on after a puncture for up to 80 kilometers at around 80 kph even after it has been punctured.<\/p>\n Most regular tyres are filled with air pressure, which helps to support the weight of the vehicle and also helps to absorb shock from bumps in the road. When a puncture occurs, the air escapes from the tyre and the tyre deflates. This can cause problems because the weight of the car is no longer supported and shocks from bumps are no longer absorbed as effectively.<\/p>\n With a run-flat tyre, there is a reinforced sidewall that prevents the tyre from collapsing when the air pressure is lost. This means that even if you get a puncture, you can still continue driving with your tyre secure until you can get to a safe place to change your tyre.<\/p>\n Since run-flat tyres have both stiffer sidewalls and a thicker sidewall compared to a normal tyres, they won’t look \u2018flat’ like a normal tyre would.<\/p>\n So, how do you know if you’ve got a tyre puncture<\/a><\/strong>, tyre failure, or pressure problem?<\/p>\n The answer lies with your tyre pressure monitoring system (TPMS). This is a system that checks the pressure in each of your wheels continually \u2013 lighting up a dashboard warning if it detects a\u00a0tyre puncture\u00a0or loss of air pressure.<\/p>\n Today, all cars are required to have a tyre pressure monitoring system as standard. As such, you simply need to keep an eye on your warnings lights to work out if you have a problem.<\/p>\n Like any product, run-flat technology have pro’s and con’s.<\/p>\n Let’s take a look at each:<\/p>\n Run-flat tyres generally have a maximum\u00a0speed rating<\/strong><\/a>\u00a0of 80kph \u2013 although some are slightly higher \u201cwhen damaged\u201d otherwise normal speed rating applies.<\/p>\n Most tyre manufacturers will recommend that you drive at this speed or less for a maximum of 80kms. This is usually enough distance to get you home or to a tyre workshop for further help.<\/p>\n It depends on where the damage is, please refer to this article on puncture repairs to learn more.<\/p>\n Run flat tyres can be repaired in some circumstances but this will vary depending on the make, model and severity of the damage to the tyre. A tyre professional will be able to assess your tyres and make the best recommendation for you.<\/p>\n Yes and no:<\/p>\n However I say replacing run-flat tyres like-for-like is always the best option.<\/p>\n Run flat tyres make sense for vehicles that don’t have space for a spare tyre or for drivers looking for a temporary solution in the event of a flat tyre. They offer peace of mind and the knowledge you won’t ever get stuck roadside or in an unsafe area if you get a flat. However, they do come with restrictions and aren’t appropriate for every car.<\/p>\n Now we have\u00a0tyre sizes explained<\/span>, it’s worth looking at other markings that can impact the tyres you need \u2013 and some tyre manufacturers have products known as \u2018Run-flat tyres’. In many cases, where a vehicle manufacturer supplies a car with run-flat tyres, they’ll recommend you always use run-flats.<\/p>\n These are designed with a tough sidewall that won’t flatten even if you loose pressure. This means there’s no need for swapping to a spare wheel or trying a roadside repair.<\/p>\n You might be asked if your tyres are \u2018run-flats’ because, as mentioned, these are sometimes added as standard by a vehicle manufacturer. If so, you’ll see see different markings depending on the brand of tyre<\/a><\/strong> on your car.<\/p>\n These tyres use an \u2018ROF’ marking on their sidewall. This stands for \u2018Run on Flat’.<\/p>\n Some\u00a0Goodyear tyres<\/a>\u00a0use the term \u2018EMT’ \u2013 meaning \u2018Extended Mobility Technology’.<\/p>\n These brands use either \u2018ZP’ or ZPS’ \u2013 an in-house designation used to identify run-flats.<\/p>\n You may see adverts from tyre retailers<\/a> that say things like \u201cRun Flat Tyres BMW\u201d, \u201cRun flat tyres Mercedes\u201d or similar. This is because these manufacturers tend to fit run-flats on their vehicles as standard \u2013 so owners are often looking specifically for replacements.<\/p>\n Although some vehicles come from the factory with run-flats \u2013 you don’t have to replace them like-for-like. For instance, a car equipped with Bridgestone run-flat tyres<\/a> will be perfectly safe if you swap to Pirelli run flat tyres \u2013 for example.<\/p>\n Overall, run-flat tyres typically have more advantages than disadvantages. If you’re looking for a tyre that will keep you safe in case of a puncture, then run-flat tyres are definitely worth considering.<\/p>\n However, it is usually a bit more expensive to fit run flat tyres compared to regular tyres and they might not be suitable for all vehicles. Do your research before purchasing run-flat tyres to make sure they’re right for you and your car!<\/p>\n If you need to replace a run-flat tyre, you’re probably not wild about the idea of calling around every auto shop nearby and getting quotes!
