CONTINENTAL CONTI CARE SELF-INFLATING TYRE

EXPLAINED

PUMPING A NEW SOLUTION INTO AN OLD PROBLEM

If you can look past the slightly saccharine acronym, Continentalís CARE (Connected, Autonomous, Reliable, Electrified) tyre showcases some intriguing technology and eliminates a reason to pull in at the servo.

While tyre-pressure monitoring systems are now commonplace in modern vehicles, the German tech giantís latest concept takes the principle to a new level with a package that looks after its own pressure.

Housed within the wheel itself, a centrifugal compressor stores a small amount of pressurised air in a receiver. If the tyreís pressure should decrease, the required amount of air is pumped back in from the self-contained tank, all without the driverís knowledge or intervention.

The set-up can reduce pressures too. In very hot weather or for loose surfaces, the CARE system can release air from the tyre and then top it back up again as the conditions change. Not only is the system calibrated to maintain optimum vehicle dynamics and safety, it minimises excess fuel usage by ensuring the correct rolling resistance at all times.

Normally, it would be good practice to check your tyre pressures once a week, but Continentalís clever system keeps an eye on them for you with every revolution of the wheel.
