Cyber Tires have a sensor that communicates with a vehicle's computers. The car knows the type of tire, whether it's the winter or summer version, the recommended pressure, the load index, and the speed rating. The system can monitor things like the level of wear, temperature, grip and slip details, the load on them, and more. Depending on how an automaker implements the tech, a vehicle can use this info to adjust the suspension settings, electronic stability control parameters, braking assist, and more.
Pirelli touts the system as providing the vehicle with data that it wouldn't usually have. The extra info allows for safer driving.
The McLaren Artura was among the first production vehicles to get Cyber Tires for its bespoke P Zero, P Zero Corsa, and P Zero Winter rubber. The Lotus Evija also uses the technology.
Pirelli is also working on a version of Cyber Tires that could network with other vehicles and high-tech infrastructure. The idea is that the tech would share information about the road surface with other vehicles.
