What are Run-Flat tyres?

What do you do when you get a flat tyre? With a run flat tyre you’ll be able to keep driving - usually at a maximum speed of 50 mph - until you can get to your nearest local Protyre garage

If you want to know whether your vehicle has run flat car tyres, check the spare. If there’s no tyre repair kit, the chances are you have these reinforced tyres. If you have a new car and no spare tyre at all, then you almost certainly have this type of tyre fitted.

How Do Run Flat Tyres Work?

Run flat car tyres use reinforced sidewalls or a reinforced support ring to cope with the loss of air pressure after a puncture. These reinforced tyres must be used in conjunction with a TPMS (Tyre Pressure Monitoring System), so you’re alerted when you experience a puncture and your tyre loses pressure.
If you have run flat vehicle tyres and you do experience a flat, don’t ignore the speed and distance limitations of your tyres. Get to your nearest Protyre garage as soon as possible.

What Are the Benefits of Run Flat Tyres?

Run flat technology allows you to drive safely in the event of a puncture:
  • Strengthened tyres have more integrity and help you keep your car under control.
  • You don’t have to change your tyre in uncomfortable and potentially dangerous situations at the side of the road.
  • You won’t need a spare tyre, so you have more space in the boot of your car and less weight overall, leading to improved fuel efficiency

Can I Switch Back to Normal Tyres?

There’s no doubt run flat car tyres are more expensive than regular tyres, but obviously they’re more convenient too. It is possible to swap out your run flats for regular tyres, but be aware that if they’re OEM equipment that decision could have an impact on your car’s suspension and handling. And of course you’ll need to purchase a spare tyre as well.
You can’t retrofit this type of tyre to an older vehicle unless it has TPMS and a suitable suspension. As a general rule you shouldn’t mix tyres on your vehicle, so don’t run conventional and run flat vehicle tyres together.

Can My Run Flat Car Tyres Be Repaired?

For safety reasons, it’s not recommended that run flat tyres are repaired. If you’ve exceeded the speed or distance limit for your tyre, then the strength and reinforcement may be compromised. As there’s no way of knowing the internal condition of the tyre, a punctured run flat tyre needs to be replaced.

How Long Do Run Flat Vehicle Tyres Last? 

Because your run flat car tyres are manufactured from conventional materials, they’ll last as long as a regular tyre. Inspect them regularly and keep them inflated to the correct pressure to optimise their lifespan.
