Why do people dislike run flats?
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. Potential ride discomfort — the stiffer construction of run-flat tires can result in a harsher and less comfortable ride, especially on rough roads or over bumps. Less responsive handling — run-flat tires can negatively impact handling and responsiveness, making the vehicle feel less agile and maneuverable.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.There are two primary categories of run-flat tire systems: Because of the thicker sidewall, it is much more difficult to puncture the side of the tire, which is beneficial because a sidewall puncture causes more damage to the tire than a tread puncture does.Run flat tires have rigid sidewalls that carry the weight of your vehicle after a puncture. Once you drive with zero pressure, those reinforcements can suffer damage—even if it’s not visible on the outside. That hidden damage makes it unsafe to repair.
What is the downside of run-flat tires?
Run-flat tire cons Less responsive handling — run-flat tires can negatively impact handling and responsiveness, making the vehicle feel less agile and maneuverable.

Many tire manufacturers, like Yokohama and Continental, recommend against patching run-flat tires.

You didn’t drive more than the manufacturer’s recommended distance after losing pressure.
Do regular tires ride better than run-flats?
