What are run-flat tyres?
Run-flats are tyres that allow you to continue driving after a puncture and maintain control of the vehicle at a speed of up to 80 km/h and distances of up to 50–90 km.
- Tyres with reinforced sidewalls
Stiff and durable sidewalls support the vehicle’s weight, preventing the tyre cord from touching the rim.
They’re made of a special heat-resistant compound.
The distance the punctured tyre can cover ranges from 50 to 90 km.
The maximum speed ranges from 50 to 80 km/h.
- Tyres with a support ring
A special ring ensures rigid support along the entire circumference of the tyre.
These tyres can withstand heavy loads.
They can be driven on without speed restrictions even after a puncture.
The maximum distance the punctured tyres can cover is up to 320 km.
- Self-sealing tyres
There is an additional sealing layer made of viscous polymeric material under the tread.
In case of a puncture, it flows out and hardens, blocking small holes and maintaining tyre pressure.
- You won’t lose control of the vehicle in case of a blowout.
- You don’t have to replace the wheel immediately and on your own.
- You don’t have to keep a spare wheel in your car.
- Run-flat tyres withstand mechanical damage better.
- You can save on roadside assistance services.
- High price
- Increased tyre weight
- A harsher ride
- Wear out faster
- Not all garages will work with them
- They can’t be repaired
