The following diagram illustrates system component interaction. 

The Tyre Tag transmits every 9 seconds and is received by both the Trailer ID Unit and the Dual Hub Unit (DHU). The DHU generates its own power and can therefore continuously monitor pressures, temperatures, vibrations and well as rotations and speed. The DHU transmits its signal which is received by the Trailer ID Unit and the Main Cab Display Unit (MCDU).

Automatic trailer identification

Each DHU is issued an unique code, allowing the signals transmitted by one vehicle not to interfere with those transmitted by another, yet trailers can be interchangeable without any manual resetting needed to be done to the system in order for the MCDU to recognise the new trailer. This is a unique feature of the N-Tyre System.
The system will only recognise a trailer that is connected to the horse, notwithstanding that it may well have had to ignore this trailer whilst it was previously linked to another horse.Each DHU has a transmitter and a receiver included in the circuitry and therefore the signals can be transmitted across large multi-trailer vehicles with 100% reliability. All information collected by the DHU is processed and transmitted via radio frequency at 433,3Mhz to the MCDU.

  1. Pressure at 7,5 bars
  2. Pressure drops 0,2 bars to 7,3 (alarm sounds, driver is warned)
  3. Pressure drops 0,2 bars to 7,1 (alarm sounds, driver is warned)
  4. Every 0,2 bar drops until 6,1 (alarm sounds, driver is warned)
  5. Pressure drops below 6,0 (alarm sounds, driver is warned, Fleet Manager is SMSd)
  6. Every 0,2 bar drops until 4,5 (alarm sounds, driver is warned)
  7. Pressure drops below 4,5 (alarm sounds, driver is warned, Controller is SMSd)
  8. Every 0,2 bar drops until 3,1 (alarm sounds, driver is warned)
  9. Pressure drops below 3,0 (alarm sounds, driver is warned, Managing Director is SMSd)

Each time that the driver resets the alarm, or an SMS or data transfer is completed, the ‘event’ is recorded and downloaded to a central computer every 24 hours.


The moment the temperature of the dust cap of any wheel varies by 20% of the average, above or below, the NTS sends a temperature alarm to the driver. The minimum temperature of an alarm is however 25°C. If the situation continues for more than 2 minutes, an SMS is sent to the Fleet Manager informing him of the problem. Both a binding brake and faulty wheel bearing are therefore detected in time.In the event of a brake failing to function normally, the temperature will not rise during usage, in which case, the NTS will notify and report on an under-functioning brake.


A vibration warning will not occur on a bumpy road as the NTS is able to distinguish between vibrations made on a bumpy road from those made by a thread separating from the casing.The NTS will produce a ‘vibration alarm’ only if a tread begins to separate from the casing, or in the event that a wheel is loose or badly out of balance.

Digital Odometer

Tyre size 1100 x 20
Rotations Kilometers
1000 3.455
100000 345.5749
The DHU counts each rotation made, sending information to the MCDU that downloads data every 24 hours to the main computer, which then calculates the amount of kilometres accumulated according to the size of the tyre.The Odometer allows 6 separate Odometer readings to be taken, thus providing multiple evaluations of the data such as; 

  • Distance covered for load
  • Distance since last overall
  • Distance travelled by driver

N-Tyre Track  

The NTS incorporates an integrated active Tag system, called the N-Tyre Track. A Tag is fitted to each tyre and can be read up to a distance of 30 metres. The system digitally identifies each individual vehicle, its tyres and their wheel positions, providing an irrefutable means of identification whether on the vehicle or not, travelling or stationary. A tyre can easily be identified when removed from a vehicle with the use of a hand reader.
The NTS automatically downloads the following data every 24 hour• Date of purchase and price• Vehicle registration• Wheel position• Any missing asset• Current asset value• Distance traveled since new• Tread depth• Number of retreads• Expected life of the tyreManagement is now, for the first ever, able to immediately identify tyres that have been swapped, stolen or replaced; accurately measure the distance travelled by a tyre, obtain an accurate cost of operational efficiency and project the potential life of the tyre; audit the asset value of tyres on the move, in the warehouse or at the retreaders; highlight potential problems before they occur, ensuring the most cost effective utilisation of one of the biggest cost centres in the transport and logistics industry.Tags are contained inside a patch and are easily vulcanised to the tyre, inside or outside.

Vehicle Tracking System

The NTS includes a Vehicle Tracking System that operates with a Global Positional System (GPS). The system is user-friendly and incorporates a digital log book, enabling management to check on all routes taken by a vehicle.

The system will immediately send 3 SMS message the moment the vehicle deviates from its intended route, providing a cost efficient means of monitoring the vehicles movements during extraordinary circumstances.
