Fertigungsreifen

Fertigungsreifen, also known as run-flat tires, are specialized tires designed to allow a vehicle to continue driving safely at reduced speeds even after a loss of air pressure. Unlike conventional tires, which typically require immediate replacement or towing upon a puncture, run-flat tires incorporate reinforced sidewalls that provide structural integrity even when deflated. This feature enhances safety by reducing the risk of a sudden tire failure and enabling drivers to reach a safe location without the immediate need for roadside assistance.

The concept of run-flat tires emerged in the late 20th century as automotive manufacturers sought to improve vehicle safety and reduce downtime caused by flat tires. These tires are commonly found on premium and luxury vehicles, as well as some performance-oriented and safety-focused models. They are also increasingly being adopted for commercial and fleet applications due to their operational efficiency and cost-saving benefits over time.

Run-flat tires come in two primary designs: self-supporting and reinforced. Self-supporting run-flats rely on thicker sidewalls to maintain shape when deflated, while reinforced run-flats incorporate additional materials or structures to support the tire’s integrity. The use of run-flat tires often requires compatible wheel rims, which may have a slightly different design to accommodate the reinforced sidewalls.

One of the key advantages of run-flat tires is their ability to minimize the risk of a stranded vehicle, particularly in remote or hazardous areas. However, they also have some drawbacks, including reduced comfort due to stiffer sidewalls, shorter tread life in certain conditions, and higher upfront costs compared to conventional tires. Additionally, run-flat tires must be replaced if they are driven on while completely flat, as prolonged use in this state can cause irreversible damage.

Proper maintenance, such as regular tire pressure checks and avoiding aggressive driving on a flat, is essential to maximize the lifespan and performance of run-flat tires. Many manufacturers recommend monitoring tire pressure more frequently when using run-flat tires, as they may not provide the same visual cues of a puncture as traditional tires.
