This section is entitled “TPMS and sensor technology” for a reason. No longer are in-tyre sensors about measuring temperature alone. Now TPMS basically means pressure and temperature, often with the addition of algorithmically generated road feedback, load information and even wear calculations. These “big data” contributions are routinely relayed to the cloud for analysis. At the same time external tread readers are measuring similarly important data and sending that to the cloud. Put all this together and we have what Pirelli calls this the “sensorisation” of the tyre business. Whatever we call it, this part of the business now about far more than just sensing tyre pressures. As far as uptake is concerned, legislation and technical innovation are the key driving forces.
