How Long Can You Drive with a Damaged Run-Flat Tire?
1 Answers
Run-flat tires can typically be driven for 250 kilometers after being damaged. However, in cases of severe damage, such as large punctures from sharp objects or poor road conditions, the driving distance may be reduced to 80 kilometers. Run-flat tires, technically known as self-supporting tires, are composed of an outer tire, a standard inner tube, a spare inner tube, a steel rim, a gas generator or air chamber, pressure sensors, and a control unit. The sidewall of an inflated tire is the main component supporting the vehicle's weight, especially for tires with a larger aspect ratio. Severe tire blowouts often lead to instant collapse of the sidewall, causing the tire to lose its support immediately and resulting in an abrupt change in the vehicle's center of gravity.
