HEALTH


Whole-body vibration (WBV) comprises the transfer of relatively low-frequency environmental vibration to the human body through a broad contact area. Motion sickness is associated with frequencies below 1 Hz. The result is a condition in which the body or a part of the body will vibrate at a magnitude greater than the applied vibratory force. In response, muscles will contract in a voluntary or involuntary manner and cause fatigue or a reduction in motor performance capacity.

In response, muscles will contract in a voluntary or involuntary manner and cause fatigue or a reduction in motor performance capacity. Driver stress leads to accidents.

Resonance of the body or its parts due to WBV causes adverse health effects, especially with chronic exposure. These include interference with or irritation to the lungs, abdomen or bladder. Effects of WBV on vision were reported as early as 1965. A 1994 Australian study identified WBV and vehicle jarring as a contributing factor to back pain in the mining industry and as a significant risk to mobile equipment operators.

SAFETY


Incorrect tyre pressures in the transport industry substantially reduces safety, while causing untold damage to drivers, and is damaging our world unnecessarily. This problem affects the stopping ability and predictability of every heavy truck on the road. This problem amplifies every pothole and bump, damaging driver’s health, while also our damaging trucks, our roads and our infrastructure. This problem wastes one tyre out of three, shortens the life of expensive equipment, and causing unnecessary waste in repair and maintenance, further damaging our environment.

Truck safety simply cannot be optimized while we continue to ignore the basics. No amount of technological aid will fix bad design or operations.

Symptoms and Effects:

• Braking/stopping distances increased considerably.
• Driver control and truck predictability is substantially reduced.
• Blowouts, tyre shredding, and truck fires are dangerous if not deadly.
• Road bumps and potholes are amplified, damaging driver health, and increasing driver stress and fatigue.
• Whole Body Vibration is a proven human health hazard.
• Poor handling and uncertain predictability increases driver work load, stress and fatigue further damaging drivers.
• Truck driver life expectancy is 16 years less than other industry averages.
• Uneven tyre wear, suspension wear, drive train wear and tear is substantially increased.
• At least a 33% increase in tyre costs.
• Wear and tear, plus fatigue damage to trucks and trailers is substantially increased, also increasing break downs and increasing transport costs contributing to unsafe operations.




The single most important component on any truck is almost always under-used. Manufacturer reco\mmendations are generally always ignored, leading to overinflated tyre and countless problems.

Most truck tyre manufacturers have truck tyre load to inflation recommendations on their web sites. If not, they refer to the US Tire and Rim Association handbook. Even Australia has a Tyre and Rim ‘standards’ book. Yet, everyone ignores them, reducing control, safety, driver health and comfort, profits and environmental damage.

AIR CTI's Central Tire Inflation System put the driver in control. With AIR CTI the driver can improve traction and control, by simply pushing a button, changing the tyre pressure to suit the load and the road. With the correct pressures in the tires, there is a dramatic reduction in wear and tear on the vehicle, reducing tire failures and eliminating most breakages. Everyone is safer.


MONEY


Modern trucks have many items that were once considered ‘unnecessary’. Power steering, heaters, air conditioning, suspension seats, air suspension, auxiliary air con, disk brakes, tilt steering, ABS, and ELB, these are just some examples. There was even controversy when radial tyres came in.

Central Tyre Inflation (CTI) or Adjustable Tyre Pressure is today’s “don’t need it” product.   Comments heard over the last 15 years include “can’t go that low, the tyre will come off the rim”, “that’s just another thing to go wrong”, “I don’t need it, I never get bogged” and “I’ll fit it when they force me to”  

Truth is, every major tyre manufacturer and every tyre association recommends adjusting tyre pressures to suit the load on the tyre, and to suit the road conditions.  Every reputable tyre manufacture has load to inflation tables explaining correct pressures, and they also explain the huge waste that even 20% over or under inflation causes.

Yet, almost every steer tyre is under inflated, and almost every drive and trailer tyre is over inflated.   Running ’traditional’ tyre pressures will waste the owner $5,000 to $15,000 per year. Indirect costs are increased down time, increased maintenance costs, and reduced operating times, all of which add up over time.  Sitting in the shop isn’t earning any money.   Downtime costs twice, extra expenses, and less income.
Any truck running off the road, or changing their loads, or runs empty, needs CTI.   Any truck that needs traction, endures being hammered by vibration, is loaded only half the time, or tyres are damaged or have a short life, absolutely need Central Tyre Inflation.

 


ENVIRONMENT


We all must live on this planet, our roads, our air and lives take a beating every day. Rough roads plagued with ruts and corrugations, overly noisy highways and streets making it harder to relax, and our air and water are being contaminated by dust, silt, and rubber particles.

Waste simply should not be tolerated in any industry.   We must minimize the cost of living here.  Wasting one tyre out of three is simply dumb.   Science has proven that the millions of tonnes of microscopic rubber particles are damaging our world.  Getting rid of all the dead tyres is a major problem, with huge stock piles ‘stored’ because we don’t know what to do with them.

Waste of trucks is equally dumb.   Prematurely destroying them with unnecessary vibration costs our world dearly.   Premature failure of suspensions, axles, wheel bearings, shocks, springs, chassis, and trucks is bad business.  Optimizing tyre pressures for the load and road makes everything last longer, costing us less, both in money, and in environment damage.

Hammering our infrastructure into dust by high impact high pressure tyres, vibrating and bouncing, costs every citizen, while increasing the high environmental cost of massive road work repairs.   We can’t afford it, our country can’t afford it, and our future can’t afford the damage and waste.

We can’t afford the human suffering and cost.  High accident rates, high human turn over, short life spans, and high human suffering effect every citizen.   Optimizing tyre pressures is safer, healthier, smarter, more profitable, and greener.

Here are some more facts:

• Optimizing tyre pressures with AIR CTI will add at least 305 to tyre life.
• Most punctures are simply maintained by AIR CTI, eliminating most road side tyre changes.
• Most blow outs are caused by punctures that deflate the tyres.
• Suspension life often improves by 50 to 90%.
• Drive train life will double in many job scenarios.
• Under inflated tyres waste fuel.  Unbalanced dual tyre pressures waste fuel.  Severely over inflated tyres may save 1%.  AIR CTI provides numerous wonderful benefits with no adverse affects.
• Truck driver life expectancy is 16 years less than other industry averages.
• Uneven tyre wear, suspension wear, drive train wear and tear is substantially increased.
• At least a 33% increase in tyre costs.
• Wear and tear, plus fatigue damage to trucks and trailers is substantially increased, also increasing break downs and increasing transport costs contributing to unsafe operations.



Evidently AIR CTI is the only practical and affordable tool that makes all of this possible and effective.  AIR CTI is an investment in our future.


TRACTION


THE PROBLEM: Virtually all transport ignores tyre manufacture operating recommendations to the enormous detriment of the industry.

The benefits of matching optimal tyre pressure in tyres based on load/tyre and cross-referenced against terrain conditions has been overlooked in the transport industry. Traditionally heavy truck tyre pressures have been based on full load conditions and were based around the original cross ply tyre. It was necessary to maintain side wall strength for control, however, since the development of the stronger side wall radial tyre loading became an equally important consideration. The new technology is still to filter through to the industry resulting in antiquated work practices and thinking pressures.

SOLUTION: To obtain the optimal tyre pressure the driver needs to take into consideration the load he is carrying on each axle and then the load on each tyre. This can be easily done at the company weighbridge. The driver needs to consider Drive, Steer and Trailer individually.

Reference is then made to the tyre manufacturer’s recommended load/inflation tables. This recommended tyre pressure is cold pressure and allowance would need to be taken into account when the tyre is at hot pressure. The driver then adjusts in relation to terrain conditions. As the driver changes load and/or terrain conditions an adjustment needs to be made. This must be done every time.

Tires are an integral part of a vehicle. Each type of tire affects overall vehicle performance and safety differently. The tire’s traction is one part of overall performance. Done in a series of controlled tests, tire manufacturers and third-party testers use consistent test vehicles in order to determine performance capability.

Tires are designed for different environments and different driving conditions. Some are designed for off-road, others for all-terrain traction capability while other tires enable drivers to navigate the highways more comfortably. In any case, tread compounds and tread patterns are important factors in wet traction and dry traction.

Most truck tyres are overinflated and as a result the tyre footprint is sub-optimal. This does not allow the tyre to perform at its maximum level. This leads to early deterioration of the tyre, fuel inefficiencies, traction deficiencies, safety issues and control problems.
