What is the disadvantage of a run flat tire?
Run-flat tire cons Less responsive handling — run-flat tires can negatively impact handling and responsiveness, making the vehicle feel less agile and maneuverable. Uneven wear and tear — due to their unique construction and potential for driving while underinflated, run-flat tires are prone to uneven wear patterns. However, run-flat tires aren’t perfect. Severe punctures or sidewall impacts may still require immediate replacement – and it must be driven at a certain speed/distance. Run-flats are also stiffer, resulting in a harsher ride, especially in vehicles with 20” or 21” inch wheels.Run-flats do not handle potholes better than conventional tires. On the contrary, because their sidewalls are much stiffer than a conventional tire, the likelihood of a side wall splitting or cracking from a severe pothole hit is greater.Yes, you can replace run flat tyres with regular ones. If you do, make sure the new tyres align with your vehicle’s specifications. The way they work, means that run flat tyres are designed to keep you on the road.

The stiffer sidewalls contribute to a firmer ride, which can lead to increased tread wear, especially if the vehicle’s suspension is not specifically tuned for run flats.
Why has BMW stopped using run flat tyres?
Run flat tyres are more likely to cause cracked alloy wheels as bumps and potholes are unable to be absorbed by the hardened sidewall. This transfers massive trauma onto the alloy wheel itself which can cause extensive damage to your BMWs alloy wheels. One cautious bit of advice, though, if you’re considering changing your BMW’s run-flat tires to regular tires, you must do so on all four tires because of the handling and performance differences between the types of tires. As a way to reduce overall weight of new BMWs, they no longer come with spare tires.

The internal structure may have been compromised, even if the tyre appears undamaged from the outside.The BSAU159 guidelines permit repairs to run-flat tyres if: The puncture is within the central tread area (not the sidewall). The damage is smaller than 6mm in diameter. The tyre shows no signs of secondary damage, such as sidewall creasing, rubber dust, cracks or under inflation damage.Run-flat tires are not repairable. After significant tire pressure loss, they are only designed to stabilize the vehicle for 50 miles. No puncture repair of these tires is possible. If they are patched up, more likely they will puncture again due to loss of rigidity and uneven wear.
Can a puncture be fixed on a run flat tyre?
Run Flat tyres are designed with reinforced shoulders that allow the tyre to continue to carry the weight of the car over a limited distance. This means the driver can continue their journey for 50 miles at a speed of around 50mph* in the event of a puncture, to a safe and convenient destination to change the tyre. It is advised that you should travel no more than 50 miles on a punctured run flat tyre, and maintain a speed under 50mph. While the sidewall of a run flat tyre is reinforced, the materials used in its construction are, in most cases, the same as a regular tyre.Drawbacks. High replacement cost: Drivers often think about the cost of replacement as one of the most significant downsides to run-flat tires. But the thick sidewalls that make them so good at their job have a significant impact on ride quality.
