Do BMWs need run flat tyres?
Yes! BMW considers run flat tyres to be safer than standard tyres due to increased stability of the vehicle following a puncture. BMW states its due to environmental concerns but also comfort.

As a plus, non run flats are less expensive than the run flat counterpart. Self-Supporting Run-Flat Tires They can travel up to 50 miles at a speed of 50 mph without any air pressure, and while they may lose some stability and handling during that drive, they won’t go completely flat.Run-flat tires have stiffer sidewalls that are designed to hold the wheel off the ground while you drive, even when deflated. However, rolling on a run-flat’s stiff sidewalls causes them to flex repeatedly, and they can bend only so many times before they fail completely.Reduced performance: Run flats may not provide the same level of performance as conventional tyres. The stiffer construction and sidewalls can affect handling and cornering capabilities, resulting in slightly compromised performance in terms of traction, braking, and overall vehicle dynamics.Can You Drive On a Runflat Tire with No Pressure? Yes, you can drive on Extended Mobility Tires (EMT) / Self-Supporting Zero Pressure Tires (ZP) totally deflated. That’s what they are designed to do. Goodyear advises that in case of a flat you can drive up to 50mph for 50 miles with zero pressure.Although there are no laws or legislation against mixing run flats with standard tyres on a car, doing so can have a negative impact on the handling of the vehicle.

How much does it cost to replace run-flat tires on a BMW?
Run flat tires are estimated to cost between $200 and $500 each. Run-flat tires are slightly more expensive to manufacture than standard tires due to the additional reinforcements included. A run-flat tire design relies on a thicker, stiffened sidewall to carry the load in the event the tire goes low or flat. Even when properly inflated, the reinforced sidewall structure is stiffer than the sidewall of a conventional tire. The added spring rate of that stiffer sidewall can be felt over every bump.Cost – A run flat tyre will usually be more expensive than a standard tyre. So, if it does get damaged, the cost of buying a new tyre will be relatively high. Performance – Another minor downside of the stiffer sidewalls is that they can reduce the car’s ability to handle corners and slightly reduce braking times.Disadvantages of Run-Flat Tyres: Potential for Increased Road Noise: The reinforced sidewalls may contribute to a firmer ride and slightly increased road noise.Run-flat tires basically have firm sidewalls. The firm sidewalls allow the tire to keep operating even once all the air is out of your tire. However, much like a spare tire, they are not meant to be a permanent solution. Without air, the tire will lose integrity and eventually fail.
