A U.S. Army soldier deploying a stinger at a vehicle checkpoint in Iraq. A spike strip (also referred to as a spike belt, road spikes, traffic spikes, tire shredders, stingers, stop sticks, by the trademark Stinger or formally known as a Tire Deflation Device or TDD) is a device or incident weapon used to impede or stop the movement of wheeled vehicles by puncturing their tires.
Reducing tire pressure also reduces the extent to which the tires grind against loose surfaces, significantly reducing dust and silt. Another function of CTIS is to maintain tire pressure if there is a slow leak or puncture. In this case, the system controls inflation automatically based on the selected pressure the driver has set.

The scrub radius is the distance at the road surface between the tire center line and the SAI line extended downward through the steering axis. The line through the steering axis creates a pivot point around which the tire turns. If these lines intersect at the road surface, a zero scrub radius would be present.
A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. [1] A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS).
The hollow spikes puncture self-sealing rubber tires. The hole in the center allows air to escape even if other ends of the tube are sealed by soft ground. Inventors patented caltrop-like devices to deflate vehicle tires in a manner useful to law enforcement agencies or the military. [18] [19] They are currently used by the military and police. [5]
Tire uniformity refers to the dynamic mechanical properties of pneumatic tires as strictly defined by a set of measurement standards and test conditions accepted by global tire and car makers. These standards include the parameters of radial force variation , lateral force variation , conicity, ply steer, radial run-out , lateral run-out , and ...
Automobile tire damaged after an impact. A blowout (also known as a burst) is a rapid, explosive loss of inflation pressure of a pneumatic tire.. The primary cause for a blowout is encountering an object that cuts or tears the structural components of the tire to the point where the structure is incapable of containing the compressed air, with the escaping air adding to further tear through ...
A run-flat tire is a pneumatic vehicle tire designed to resist the effects of deflation when punctured, allowing the vehicle to continue to be driven at reduced speeds for limited distances. First developed by tire manufacturer Michelin in the 1930s, run-flat tires were introduced to the public market in the 1980s. They have increased in ...
