How Long Do Run-Flat Tires on Mercedes-Benz and BMW Last?
In the past, vehicles and crossover would deploy lightweight, temporary spare tires that do not give reliable performance and longevity. Temporary spare tires are designed to be simple to replace in emergency situations, but they only last for 50 miles and have a recommended top speed of 55 mph. They also take up important cargo room in the trunk of the automobile. Many luxury automakers, including Mercedes-Benz and BMW, have moved away from this technology in favor of regular run-flat or extended mobility tires, which offer a 50-mile driving range without the trouble of needing to change a tire.

When you get behind the wheel of a luxury vehicle with run-flat tires, a Tire Pressure Monitoring System will be installed to make sure you maintain a safe level of performance. This system will alert you when the tire pressure drops.

The ability to drive on Run Flat Tires is their main advantage. They let you keep going, even after all the air has been expelled, for 100 miles on a level road. Instead of stopping on congested roads or in less desirable areas of town, drivers could safely slow their speed until they reach the destination they require. A quick deflation causes less weight transfer and tread instability because this tire can sustain the weight of the car for miles without air. Above importantly, the handling and steering will continue to be close to normal. The advantages don’t end there. Your vehicle’s weight should decrease once the spare tire and tire-repair tools are gone.
