Here’s how it works: A sensor on the interior detects when pressure has dipped too low. A valve mounted on the sidewall opens up, and as the tire rotates, the vehicle’s weight compresses a tube built into the tire’s circumference that injects air to increase tire pressure. Once it hits the optimal psi, the system shuts the valve and the ride proceeds as normal.
Add to this system compatibility with re-treaded tires, and it’s an appealing package, especially for trucking companies. Goodyear hopes that with installation in commercial transportation, they’ll be able to gather data to optimize the system for peak performance on the road.
