The context that N-Tyre plays a role is evolving and expanding and the platforms within which it features are as follows:
- The International Agenda – Climate Change & Carbon Emissions Reductions
- The National Agenda
- The Transport / Logistics Industry
1. The International Agenda – Climate Change & Carbon Emissions Reductions
Durban recently hosted the COP 17 Climate Change conference. Carbon emissions reduction is an area where there is much opportunity and potential for N-Tyre. Our recent research and documented results show that the average tyre pressure under-inflation in South Africa is running above the global average. Just by measuring and correcting the tyre pressures to the correct manufacturer specifications, the immediate cost-saving is :
- extended tyre life – in fact the average re-treads per casing in South Africa is only 1.5 – yet the manufacturers guarantee a re-tread capacity of up to 6 times per casing. Our data reveals the significant cost-savings; even if we increase just one re-tread per casing.
- reduction of unnecessary additional fuel consumption – firstly, this can be quantified as a direct cost and secondly, linked to the climate change indicators, specifically carbon emissions reduction, this can be quantified in reduced carbon emissions based on lower fuel consumptions.
Our research has also included, based on the actual incidents of tyre-related costs (run-flats, blow-outs, tread separation and shredding, bearing failures etc) N-Tyre Systems can reduce expenditure of tyres by 35% and reduce fuel consumption by 3%.
President Jacob Zuma has committed South Africa to reduce its carbon footprint and emissions by 34%. This is a tall order, given our reliance on fossil-fuel and coal fired power. Assume, based on the recent commitment to build Medupi and Kusile caol-fired power stations, we are unlikely to see much contribution from Eskom. After Eskom, the logistics / transport industry is the highest contributor to and of carbon emissions
This positions the logistics and transport industry to meaningfully engage carbon emissions reductions. Already the carbon tax on new vehicles is testimony to the opportunity.
This industry is driven by the primary maintenance and upkeep costs of fossil fuels and tyres.
Technology has made major inroads on the fuel side, but to date, until N-Tyre, there has been little investment into tyre maintenance technology with the express purpose of extending tyre longevity and sustainability through information management of measurements and monitoring of tyre pressures, tread wear, bearing and brake temperatures.
2. The National Agenda
Government, through the Department of Environment Affairs & Tourism, has gazetted in Feb 2009, new specific Regulations to Waste Tyres under the Environment Conservation Act (Act 73 of 1989). It is estimated that the legacy stockpiles of waste tyres amounts to 60 million tyres, and current waste is in the order of 10 million tyres per annum.
Waste tyres are an environmental problem – they do not decompose, are a pollutant and breeding ground for mosquitos. Unfortunately, with current technology, there is no economically viable recycling solution. Against this context, Government has requested the tyre stakeholders to present a solution to this problem of waste tyres.
The South African Tyre Recycling Process Company (SATRPC) and the Recycling & Economic Development Initiative of South Africa (REDISA) presented their plans to the Minister of Environment during the course of 2011.
In December 2011, REDISA was gazetted as the preferred partner. Although there have been legal challenges and issues pertaining to the date of implementation, the waste tyre regulations will prevail. The process has extended the public comment phase till end April 2012.
The National Waste Management Strategy, published in Nov 2011 by the Department of Environmental Affairs, presents the Waste Management Hierarchy.
This national strategy informs and directs the agenda and context for the SATRPC & REDISA proposals.
N-Tyre is well positioned in terms of its technology and value-added service to clients – at its very design, it is primarily geared to avoid and reduce waste.
Tyre longevity and sustainability are enhanced by the patented monitoring and measurement of tyre pressures, tread wear, brake and bearing temperatures.
The N-Tyre System is designed to provide corrective action to variances detected from this monitoring and measurement
The first corrective action is to maintain correct tyre pressures. The response to any variable that signals an alarm is a proactive warning to the driver who is alerted to the identified problem.
The secondary focus of N-Tyre Systems is to extend the lifespan of the casing through re-treading, in line with the manufacturers specifications.
The more the tyre has operated at correct pressure, the better it can present for re-treading. Just increasing the re-tread factor by 1 re-tread per tyre casing, already the waste tyre downstream impact is immediately realised.
3. The Transport / Logistics Industry
There are a number of scientific and academic thought leaders in the industry. N-Tyre has recently made contact with highly regarded experts in their field, with the intent of publishing some of the research findings of N-Tyre Systems.
The incredible data generated by the N-Tyre System every second, can now be used to substantiate and validate the theoretical values from surveys done on a fraction of the industry and at an infinitesimal moment in time and then extrapolated to the entire industry as the norm!
Not only will this create a new platform of awareness and exposure, but it will lend much credibility to the product and service of N-Tyre Systems.
Similarly, the industry has its own value-added service and / or product niche market leaders. We have met with such players and are progressing further synergies.
The N-Tyre System service and product is more than just the end-user consumer deriving immediate cost benefits. To date, the thrust of the marketing and awareness has been directly to such end-using consumers. N-Tyre is expanding and intentionally targeting a more refined brand awareness. N-Tyre is leveraging the increased environmental consciousness and focus in the context of the international and national agendas of tyres and the contribution to waste and carbon emissions reductions.

Recycling levy imposed on tyres
Jan 17 2012 14:28 Sapa
Pretoria – A recycling levy on tyres will be introduced next month, the department of environmental affairs announced on Tuesday.
Chief director for waste management Nolwazi Cobbinah said the levy would become effective on February 1.
She said the production and importation of new tyres in South Africa would be subjected to the R2.30 a kilogram levy, to be used for the collection and recycling of tyres by the Recycling and Economic Development Initiative SA (Redisa).
The levy, which was announced earlier this year, is part of the integrated industry waste tyre management plan and will be put into effect and managed by Redisa.
The income generated from the levy charged to tyre manufacturers and importers will be used for the collection of tyres, distribution to recyclers and research and development.
The plan aims to create jobs and small and medium businesses in communities throughout the country.
Water and Environment Affairs Minister Edna Molewa said she did not see the resultant recycling of tyres leading to a spate of tyre thefts from parked cars.
She said the levy would “be ringfenced” for Redisa and would not end up in the general fiscus. All those involved in the tyre industry – manufacturers and importers – have to register with Redisa by January 31.
The South African tyre industry produces more than 10 million scrap tyres a year.
Redisa estimates between 60 and 100 million scrap tyres are stockpiled in South Africa.
Waste tyres pose an environmental problem, both as pollutants and as breeding grounds for mosquitoes and vermin.
Apart from tyres being burnt for their steel, used tyres can be burnt for energy production, used in the asphalting of roads and in the production of shoes.
“Anyone who uses tyres for energy must have the appropriate technology,” said Deputy Water and Environment Affairs Minister Rejoice Thizwilonde Cobbinah said she expected a total ban on tyres being dumped at landfill sites within the next five years.

Overview of the Industry
Whilst the under-inflation of tyres is the single biggest cause of excessive tyre-wear, the operating cost of truck tyres is the second most expensive item from ay trucking company, after diesel.
Driving a loaded truck on under-inflated or flat tyres causes substantial heat build-up and distortion of the profile, which destroys a tyre completely; not just the tread, but the side-walls and the carcass – the shreds of tyres found along side roads are testimony to this. An under-inflated tyre also increases drag and consequently excessive fuel consumption.
When a ‘flat’ occurs on a side-by-side dual tyre configuration, the good tyre then bears the load of both, causing unwarranted wear. If this condition persists, the two tyres bulge and rub against each other causing tremendous heat build-up in both tyres – the result of course, is the destruction of both; a costly puncture not to mention the down-time of the vehicle.
Globally, it is quite common to see shredded tyre debris on the highways and byways. These large chunks of rubber pose danger to not only the truck itself or other road-users, but to the environment. The repercussions from a single tyre shred could inflict substantial financial damage and impact on company image. The millions of bits of tyre fragments and discarded casings have a detrimental impact on the environment – 75% of all roadside ‘flats’ are preceded by a slow leak.
A single bus accident highlights the need to protect human life. The vast amount of revenue spent to encourage tourism, further accentuates that need to protect traveller visiting our country from abroad, whilst travelling in buses with potentially hazardous and unprotected tyres.
|Now, for the first time, an accurate and almost instantaneous stock – take and valuation of a company’s tyres can be obtained with the NTS.
Fuel wasted due to the under-inflation of tyres will be saved, directly improving bottom line profits.
The NTS digitally monitors tyre pressure accurate to 99.5%. The accuracy of most analogue gauges can vary by as much as 60%, resulting in dangerous and unacceptable inaccurate readings. These analogue gauges render regular and diligent checking of tyres futile.
The NTS is self-powered and self-checking and thus a hassle-free device that provides multiple benefits. With the current price of fuel and tyres, the NTS can save truck operators large amounts of money in fuel, tyre costs, down-time and increase productivity whilst simultaneously providing information necessary for the prevention of tyre related accidents, losses and/or hi-jackings.
The information provided by the NTS in digital format is invaluable in assisting management to be proactive in preventing and rectifying unnecessary losses. The NTS makes informed, efficient and cost effective decisions pertaining to the feasibility of retreading fleet tyres.
Q. Why does the N-Tyre System (NTS) need to generate extra power when other systems merely employ long-life batteries?
R. Generating the extra power enables the NTS to process many sources of information simultaneously and submit a ‘data pulse’ every 15 seconds to the Main Control Display Unit (MCDU). Instead of merely monitoring tyre pressure, the NTS monitors many critical areas of operation and collects continuous data on the truck’s performance.
Q. How does the NTS pay for itself as a product?
R. The NTS is a product that very quickly pays dividends for the user. By catching problems such as leaking tyres, faulty brakes, bearings and detecting tyre tread separation,; the unit improves tyre retreading ratios, save fuel, prevents costly accidents, can decrease insurance premiums and excesses as well as reduce road damage and saves lives – not bad for only one product!!
Q. Because the N-Tyre main control display unit (MCDU) takes the place designed for the radio, does it mean that I will be without a radio facility?
R. Not at all! The MCDU has a built-in radio facility as well as an integral GSM unit. The radio will automatically fade out when warning signals are received from either the Hub Units or an incoming cellphone call. The system is also ‘hands free’ adding another NTS safety feature.
Q. When a trailer is changed between ‘horses’, does the operator have to manually input new data to advise the system of a trailer change?
R. No. The NTS automatically identifies the change (or addition) to trailers as soon as it starts to move above 10KMH . Each trailer is equipped with a separate transmitter (TIU) which helps the MCDU identify which trailer is attached.
Q. If I have an NTS do I also need to ‘tag’ all the tyres?
R. You don’t have to, but it makes the system much more effective and informative. By installing I.D. tags onto each tyre you are able to capture all the relevant data for that tyre including Date of purchase, make, specification, distance travelled, location, punctures experienced, number of re-casings, percentage wear and it even gives the tyre a value !!
Q. How is the data that the NTS accumulates, transmitted?
R. The MCDU stores all the relevant data sent from the hub units and can either download ‘on-line’ via the GSM link, or wait until the vehicle returns to the depot and then download data to a mainframe computer via a gate reader. (A laptop could also be used to download the information at any time).
Q. If the NTS has a built-in GSM system, can I use this for Geomapping or as an anti hi-jack system?
R. The NTS has its own geomapping facility which enables the system operator at the depot to load up any given route and set parameters for that route (for example, no deviation of more than 200M from pre-determined route). Negotiations are also underway to enable NTS users to link in with satellite tracking security companies at a reduced rate.
Q. Will I get a reduction in my insurance Premiums or Excess?
R. Because the NTS offers a considerable potential saving by the prevention of accidents and consequential damage, it should be possible for you to negotiate with your insurance company for a reduction in rates and lower excesses. NTS is also currently negotiating with major insurance companies on your behalf, and will advise all interested users on the outcome.
Q. Can the NTS give me comparisons between tyre makes employed?
R. Definitely. If the tag system is installed along with tyre makes then the NTS will log relative performances and failures. Which can assist the fleet owner to make evaluations and assist in future purchasing considerations.
Q. Can the NTS assist in analysing truck performances on different routes?
R. Yes. The NTS ,by virtue of logging all data whilst on any specific route, can be employed to analyse a specific route for punctures, break, bearing or tread separation statistics. Because it is also logging distance travelled, it can even tell you where the main problems occur during any given route thus enabling the driver to be extra cautious on areas highlighted as problem areas. It can also supply data on the costs of such a trip which will assist the costings department in quoting more accurately for any future trips.
Q. How does the NTS keep track of tyres sent to a Retreader?
R. The best way to monitor tyre movements to any given Retreader, is to ensure that the retreading company has an NTS ‘reader’ installed at the gates of their premises. This will enable you to know the tyres have gone into their premises and when they were dispatched. Your own gate reader will log the tyres coming back from the Retreader.
Q. Can a truck be stopped from leaving the depot if any of the tyres are under-inflated?
R. Yes. If the gate reader is linked to the operation of the security boom or a clearance system for security guards. The pressure reader can be set for any level that the company considers as critical. If the truck attempts to leave with any tyres below this pre-set level, then the boom will not lift, or the guard will be alerted. An audible siren can also be installed as part of such a system.
Q. How can the FD access data on the tyre stock in the company?
R. If the company has tagged all its tyres (recommended) and installed readers and followed all the procedures, then he can check tyre location and estimated values at any given time, by accessing the data from his mainframe computer or from the Website which can host your company’s specific data.
Q. Can the NTS supply an overall statistic as to how many retreads are being averaged for the tyre fleet?
R. Yes. By storing data transmitted from the vehicles’ MCDU, the NTS can tell you what your average Retreading ratio is for your entire fleet. It will also give you a history for comparison purposes so that you can check on company performance in this important costing area.
Q. How much manual input is required for maintaining the NTS database?
R. If the Tag system has been installed, then only the initial I.D. data on each tyre has to be detailed into the computer for subsequent history compilation. This is far in advance of any other existing software tyre data system most of which require considerable and on-going data input on a manual basis. The NTS thus cuts down on labour, as well as eliminating human input error which detracts from the efficacy of such systems.
Q. Will the NTS warn the driver if he is exceeding the specifications of any given tyre on his horse or trailer?
R. Yes, if the system incorporates the tag system, then the specifications of any particular tyre will be monitored by the NTS. Should the driver exceed speed or loading specifications of that tyre a warning will sound in the cab as for other critical areas of operation.
Q. If I don’t have an adequate computer system, will I lose the ability to access data produced by the NTS and the tag system?
R. In the event that you do not have an adequate computer system, NTS have the facility to log all your company’s specific data and host this information on our Website. You will be given a unique password which will enable you to access all your accumulated data over the Internet
Q: Can the NTS be used to indicate the condition of a Bus (for example) at the time of an accident?
R. Yes, because the NTS logs all information on a continuing basis, along with a real time clock facility, these details show:
1. The speed of the bus
2. Tyre condition (if puncture or blow-out was a factor)
3. Whether overheating brakes or bearings caused a wheel lock-up
4. If a tread separation took place.
5. If the driver had ignored warnings prior to the accident.
Q: Will the NTS warn you in the event of a Hub Unit’s battery running down too low?
R. Yes, the main control unit in the cab will warn you of such a condition. It will also warn you if the hub unit has stopped sending signals for any reason.
Q: Can a hub unit be swapped from one trailer or horse to another?
R. Yes, a hub unit can be swapped at any time and will not affect the data on the MCDU at all, however, the hub unit will need to be reset if it is installed in a different wheel position.
Q: What is the expected life of the NTS system?
R. The hub unit’s battery has an expected life of some 5 years. The hub unit will give more than 10 years’ service and the MCDU should last for 20 or more years, as there are no moving parts at all in the unit.
Q. The NTS does not currently have a front hub unit, is this being looked at?
R. Yes, the design will be a little different to the DHU but will be available early in the new year.
Q. If a spare tire is swapped with a faulty unit, will the NTS pick up that it was the spare that was employed?
R. Yes, there is a facility for this but it relies on the N-TYRE TAG system being employed for all tyres.
Q. Will the NTS pick up that a wheel is badly out of balance, or has loose securing bolts?
R. Yes, the system picks up either condition through the ‘Vibration’ warning mode.
Q. Is the NTS easily changed from one truck to another when upgrading the fleet, for example?
R. Yes, removing the Hub units, the MCDU and the receiver/transmitters will not take long at all.
Q. Can the GPS system incorporated in the MCDU be employed to set up zones where off-loading is permitted and thus prevent unauthorized offloading of goods?
R. Yes, such zones can be set up and ‘Reed’ switches can be installed to detect if a door is being opened as added security for ‘closed’ vehicles.
Q. What are the main wearing parts and how long will they last?
R. There are very few wearing parts on the NTS. The battery in the TAG will last around 4 years and the pack in the DHU around 5 years. The generator has a pendulum supported by a bearing, but is easily expected to last 10 years – as it has been ”over-engineered”. The balance is made up of electronic components, which could easily last 20 years!!
Q. Is it possible to employ the N-Tag system without the DHUs?
R. Yes, this is feasible but would severely limit the information you could expect to obtain from the system. Such a system would auto-locate on which truck (not wheel position) your tyres were installed and, possibly, the mileage traveled depending upon the type of odometer fitted. Any other information would have to be uploaded manually but into the NTS Hand Reader, before and/or after each trip.
Q. What happens if a TIU goes down?
R. The driver will be alerted within 2 minutes of the failure but the DHUs info will be lost until the TIU is repaired or replaced
Q. What happens if the DHU goes down?
R. Within 2 minutes the driver will be alerted .
Q. What happens if the Website is down?
R. The system will inform the driver and H.O. accordingly and the MCDU will continuously attempt to upload.
all data is thus retained in the MCDU ( sufficient back-up power for several months!)
Q. What happens when the MCDU goes down?
R. All current stored information relating to the ‘horse’ will be lost, but all other data is retained by TIUs
Q. What happens if the hand reader fails?
R. Non down-loaded data will be lost.
Q.What happens when the DHU Heat sensor fails?
R. There will be a warning via the MCDU that a temperature sensor has failed
Q.What happens if a pressure sensor fails on the DHU?
R. It will show up as the tyre as being flat on the MCDU
Q. How much labour do you save when pressure-checking with an NTS (also saves labour by obviating hand-written reports)?
R. The labour-saving capability of the NTS is one of its main features. How much labour any given company will save, depends on the amount of effort they put into their tyre management operation. It is conservatively estimated that the NTS will save between R500 – 2,000 on labour and calibration costs
