For 20 years Magnum Spike has been successfully stopping fleeing vehicles. Magnum Spike is still the only hand deployable system that consistently and predictably stops Heavy Goods vehicles, self-sealing and the toughest run-flat tyres as shown in 7 out of 7 US National Institute of Justice tests.
Across the U.S. and around the world, through thousands of successful stops, there has not been a single reported adverse incident since day one! .. A 100% safety record!
When seconds count, there’s no time to measure the spikes in your tyre deflation device and wonder if they’re up to the task. With today’s tyre technology, not only the spike size, but also superior design makes the difference.

Safety, Deployment, Simplicity of Use: The key objective in designing the patented MagnumSpike is safety and ease of use. The system is very easy to handle and can be deployed in seconds under any weather conditions or road surfaces. It allows officers complete control of the situation without exposing themselves to dangerous traffic. MagnumSpike is proud of its 100 percent safety record. Many patrol vehicles place the MS16 MagnumSpike behind the co driver’s feet on the floor of the vehicle, this allows the system to be deployed seconds after the patrol vehicle stops saving valuable seconds rather than extracting the system from the vehicle boot.
Predictable Stops: The MagnumSpike is the only TDD spike that is designed to safely and swiftly end high speed pursuits consistently within a predictable short distance. It gives back officers control over an extremely dangerous situation, preventing property damage and safeguarding the lives of Police officers, innocent bystanders and the occupants of the pursued vehicle.
Vehicle Types: MagnumSpike is effective in all conditions and circumstances. Every HIT is a STOP. You do not need a different model for larger vehicles. The same system can stop all vehicles from small saloons to tractors and heavy goods vehicles.
Value & Service: The MagnumSpike is the ultimate solution to all of your high speed pursuit problems. It is far superior in every way and at a price that is substantially lower than any other tyre deflation device on the market. This allows you to stretch your budget and equip more patrol vehicles. And our after sales service cannot be beaten.
Warranty: Our warranty covers any and all components, including spikes, which are guaranteed for five years while in use and replaced free of charge.

Placing a MagnumClaw under the tyre after you’ve pulled over a vehicle will prevent high-speed chases. The 2-1/2" patented spikes come in a collapsible folding case that is laid flat under the tyre of the stationery car at a check point or in a situation where the driver of a vehicle has been stopped for questioning.
If the vehicle moves the spikes are released into the tyre from the MagnumClaw instantly penetrating and totally deflating the tyre, thereby preventing the driver from fleeing and initiating a high-speed chase.
