PIRELLI HAS COINED THE CATCHY name Cyber Tyre. Other manufacturers are working on similar but haven't launched. We're talking about a tyre that can introspect on its own health, and examine the road it's rolling over, and report to the car. Among other benefits this brings usefully earlier warning of danger, and more sensitive ABS, ESP and traction control.
Yes we've had pressure and temperature sensors before, but mostly in the valve, which isn't so accurate or immediate. The Cyber Tyre's sensors are tiny chips right in the tread. They take acceleration measurements in both the three linear dimensions and twist, which passes up to a control unit that can calculate deformation and contact patch size. Similar chips sense pressure and temperature.
If the tyre's contact patch shrinks, the car's…
