Some airlines may pay for their tyres by the retreads. There is an initial payment for the virgin tyre, and then a subsequent payment for the initial retread and further payments until the tyre account is settled. If the tyre fails prior to the final payment being made, then the tyre manufacturer wears the cost.

The secret (not so secret really!) to a successful retread programme is the pressure maintenance regime. If the appropriate pressures are applied to the tyre during its initial life, then we are able to deliver a sound virgin casing/carcass to the retreading plant.

In speaking with so many retreading facilities, they all detail a high rejection rate of casings submitted for retreading. The primary reason for rejection is the breakdown of the tyre’s structure as a result of under inflation.

So how does this affect the use of resources and subsequent emissions?

I have sighted figures purported to have been produced by the global accounting firm Ernst & Young (now EY), which detail a 70 percent reduction in natural resource extraction, 19 percent reduction in water consumption (potable water is one of the next global issues to deal with) and 21 percent reduction in air pollution. A truck tyre casing (say 11R22.5) that is retreaded will reduce oil consumption by about 50 litres – obviously more for a larger tyre.

Many tyre OEMs do promote the retreadability of their casings; it is just plain economic sense when you stop to think about it. Acquiring a product where you use 30 percent (by weight) only to then throw the rest onto the scrap pile is economic stupidity, but that is what seems to happen in most road transport organisations.

Maintaining tyre inflation pressures is too difficult, they say. Well, yes, if you are stuck in the 1950s where the only way to check inflation pressure was to use a manual gauge. In the 2000s, we started using tyre pressure monitoring systems (TPMS) to gain real time information about tyres in operation. Now we can stream data and identify issues such as binding brakes, wheel ends in failure mode as well as inappropriately inflated tyres. We’ve tuned operating tyres so that tyres operate in unison or as a team across an axle and so over the entire vehicle. Not being able to view tyre pressures in real time is so last century.

By tuning the inflation pressure of a tyre, the structural integrity can be assured so that when the tread worn tyre is presented at the retreading facility, it is accepted rather than rejected.  Thus, a serious saving in resource use is generated; there is a substantial reduction in emissions as well as reduction in land use both from the initial growing of the natural rubber to the reduction of land fill.

A simple act can generate substantial savings. Why do so many educated people ignore this aspect? Why do bean counters not consider tyres in a holistic manner?

Purchasing a ’cheap’ tyre may appear to ‘save money’, but more often than not, the cost of operations actually rises. HOW? I hear the abacus jockeys cry!  A low-cost tyre more often than not has a higher rolling resistance than a quality casing. Research and development costs, low cost operators that have copied or cloned don’t bear these costs.   Consider the fuel burn over the life of a tyre, say 150,000 km. A two percent saving on the fuel burn equates to how much? When we consider the actual life of the low-cost tyre, more than likely it requires more maintenance, so there is more downtime, added rotations to gain the maximum wear from the tread package and then there is the disposal fee on the spent casing as it cannot be retreaded.

Considering tyres in a holistic manner is not something bean counters consider or actually even know about. Tyres directly influence the fuel burn of a vehicle, the wheel end life and the suspension life, even affecting the driver’s fatigue levels – not to consider the environmental aspects such as emissions and disposal.

So if an aircraft can take off and land safely on retreaded tyres, then why can’t on-road transport trucks use retreaded casings? It comes back to the neglect shown to the tyre during the initial life. It seems that people just don’t care; they don’t understand the criticality of appropriate tyre inflation pressures.

Within the Performance Based Standards for high performance trucks operating on Australian roads (think triple trailers running quad axles), there is a statement that succinctly details what a tyre contributes, to wit  ;

“All the forces needed to both support and guide a vehicle ultimately arise in the area of contact between the tyre and the roadway. These forces are generated at the road surface in response to the deformation of the tyre structure.”

As tyre deformation is the product of inflation levels, there is a direct relationship between tyre inflation levels and vehicle safety. Why do people choose to ignore tyre inflation when it is so easy to monitor and comes with so many positive benefits?

So installing a simple regime of monitoring tyres in real time tyre casings to evidence   that the tyres have not experienced a low pressure event (so destroying the casing’s integrity) means they can be selected for retreading. This eliminates the main excuse for not retreading, i.e. the rejection rate is too high. It is that simple!

A cheap tyre is not necessarily an economic positive. A well-maintained quality tyre will generate savings upon savings and then will also be able to do it all over again after retreading.

Many governments mandate the use of retreaded tyres on utility vehicles as it is well understood there is not only an economic benefit but an environmental benefit too!

If we, the global community, continue to consume resources without considering a reduction in the rate of consumption, then we’re doomed to exhaustion. Using a resource (read tyre) at only 30 percent and then disposing it of does not make any sense (nor cents!). Retreading of tyres is a sound practice based upon sound science. Why are so many businesses throwing their hard earned cash away because the abacus jockeys don’t know and don’t care about tyres?

Success does not reward a lack of effort. How much effort are your bean counters making in respect of tyres ?
