Please forgive my indulgence on the topic of tyre testing, but the end result of a safe tyre is, the tyre is only safe IF the appropriate inflation pressure is used!

The physical road testing of a pneumatic tyre is the last part in a very long line of testing procedures used to manufacture the tyre. The actual manufacturing is not the end of the line as the tyre has to be competently mounted to a wheel and then appropriately inflated prior and during use.

If the tyre/wheel assembly is not balanced in mass and dimension, then the tyre is not going to perform as expected, nor will the tyre perform as expected if the inflation pressure is not appropriate to the load and speed the vehicle is going to be utilised at.

The humble pneumatic tyre is a composite assembly of many different materials, each having to work in harmony and unison with each other.

The different materials used to manufacture the tyre have already undergone substantial testing as individual products to assure the sought-after properties and qualities are exactly what is required to produce a tyre that is not only safe but performs as expected.

Many years ago, on a major construction project in Asia with one of my clients, the tyre company I was an engineer with suffered many catastrophic tread separation failures. This was a time critical project so having haul trucks out of service was a serious impediment to achieving the extensive earthworks required. A long story short, I was given to understand that there was a change in the supplier of the carbon black used in this particular tyre tread specification. The fresh manufacturer’s product checked all of the (then) testing parameters, but when it came to actual live service, there was a deficiency somewhere. I was never privy to the actual product details, just the end result of seeing haul trucks with fuel and hydraulic tanks on the ground having been slapped off by tread packages parting from the tyre casing. Having up to 1,000 kg of tread rubber flapping out of control is not conducive to a safe operation.

The testing regime for the product used was seemingly insufficient to identify this issue pre-production, ending up with very costly results.

One can read in various publications of tyre testing where a group of journalists and motoring writers take vehicles fitted with various tyre producers’ products around a circuit in an attempt to quantify the performance, in lap times, but more importantly, in feel.  ‘Through the seat of your pants’ is a commonly used phrase.  As a young two-wheel motorcycle racer, I progressed from using treaded road tyres to a full racing slick. The feeling was totally different and, to be honest, I didn’t ever get the slick tread tyres to operate as they were designed.  After progressing to three-wheel bikes (sidecars), slicks became the ideal product.

In todays’ tyre production world, I suggest that the development on MotoGP motorcycles leads the way. Think of a MotoGP bike where cornering lean angles of up to 65 degrees, yes 65 degrees, are common place, all the time transmitting a power to weight ratio of more than 1:1, which is more than one horsepower per kilogramme of weight (including the rider!).  When combined with the technology developed in the giant OTR tyres used in mining, the development of tyre performance is progressing rapidly. The ability of a giant mining tyre to support a load in excess of 100 tonnes per tyre (think 50 average passenger cars, yes that’s per tyre) whilst travelling at 60 km/hr is an everyday event for a mining operation. These tyres on a drive position transmit thousands of horsepower to motivate the truck. These numbers are far in excess compared to your daily drive!

A passenger car tyre benefits greatly from all of this research and development leading to the actual physical testing of the tyre in the hands of the journalists pushing a car around a circuit.

Yet, all this testing can be undone by the end user’s reluctance to verify that the tyre’s operating pressure is appropriate for the duty cycle being undertaken. The adoption of real time tyre pressure monitoring (TPMS) has generated an increase in safety IF the driver actually uses the data.

Race pilots (drivers and riders) carefully study the operating tyre pressure detail as they well understand that just ½ a psi may make the difference between winning or finishing off the podium.

Alas, our industry has not really educated the daily driver to the critical importance of ensuring their tyres have the appropriate inflation pressures installed. Inflation, it seems, is only important to economists and price rises.

All the material testing, quality control in production and physical mounting of the tyre can be undone by the ignorance of the end user in not attending to the inflation pressures adequately. No matter how deep the science used, the quality control measures employed within production our product’s success remains at the whim of the end user as to whether they can be bothered to ensure the very item that provides their safe passage is indeed fit for purpose.

Regardless of the impressive advances in testing technology, the serious quantitative leaps in the use of computer aided design and manufacture, the improvements in material science yielding growth in all the useful features for a tyre combined in production benefitting the end result can be undone by end user apathy. As an industry, we have a programme of continuous improvement, but does the end user have the same? Do they care?

For all the testing programmes we, as an industry, have in place, the one lacking I feel is the understanding of the level of knowledge from the perspective of the driver. Do they understand the information that the physical tyre testing provides? In the case of a motoring enthusiast, very much yes, but they make up a small percentage of the population.

The advent of the Euro 7 standards will draw the performance of tyres into the everyday realm for the legislators and regulators. Again, how the daily drivers that use their vehicles for commuting actually care is an unknown, and I feel that the care factor is probably less than zero.

In speaking with learner drivers, I ask whether the driving instructors had mentioned tyres at all and was totally unsurprised when the answer came back as a no. I know I have said before that unless we can engage drivers into understanding and appreciating their tyres’ contribution to their personal safety whilst driving, then our industries progress will be stymied.

All the progress in material science, advanced vehicle standards, wonderful testing regimes can all be negated when the vehicle driver ignores the very basic of the tyres operating requirement – the appropriate operating inflation pressure. 

How we change the mindset of the end user is still testing my knowledge and patience; it is more than tiring to keep on hearing that people don’t even acknowledge the benefits they enjoy from the use of the product our industry produces.

Please educate the end user on the critical importance their tyres have in overall on-road safety. Look after your tyres, so when you call upon them to look after you, they will be appropriately equipped to do so.
