Abstract
Modern vehicles are equipped with many systems that monitor the security of driving. An example is the tyre pressure monitoring system that shows a fault if the tyre pressure is lowered. Low tyre pressure or no pressure at all (0 kPa) means that continuing driving may lead to a dangerous situation. Prolonged driving of the vehicle at 0 kPa in the tyre ends with tyre burst, rim damage, or even loss of stability. Therefore, on the automotive market, manufacturers offer Run Flat tyres adapted to emergency driving with a pressure of 0 kPa. This article presents the results of an experimental research in the field of vehicle dynamics, continuing driving a vehicle with a loss of tyre pressure. These tests were carried out not only to confirm the data provided by tyre manufacturers and to verify the vehicle's driveability but also to analyse the effectiveness of stopping vehicles equipped with this type of tyres using, for example, police studs, especially when vehicles are used for crimes or terrorist activities.

In the case of using a vehicle equipped with Run Flat tyres, which, according to the manufacturers' declaration, despite the lack of air pressure, it is possible to continue driving
The history of Run Flat tyres began before World War II
Summary
Motor vehicles are used by terrorists for attacks. In recent years, there have been over a dozen attacks in which many people were injured using cars. The history of Run Flat tyres began before World War II. The development of the technology took place during World War II, and further work in this direction was carried out after its end. Tyres of this type have been used on a larger scale since the end of the 1980s. The Run Flat technology is becoming increasingly popular. There are more cars on the market equipped with this type of tyres, which allow driving for a distance of 80 km after tyre damage (pressure 0 kPa) at a speed of about 80 km/h. Run Flat tyres can generally be divided into three segments: with reinforced structure, self-sealing, with support ring
