New tires often arrive with painted bands running across the tread, and those stripes have nothing to do with grip or performance.
The markings are a production-line detail, according to Carscoops, and their purpose is practical rather than technical.
A Production-Line Secret for Factory Inventory
The colored stripes serve as an organizational aid that keeps factory inventories in order.
Rather than signaling a special compound or a traction advantage, the bands help distinguish tires during production and storage.
That makes the stripes a behind-the-scenes part of how tires are tracked before they reach a vehicle.
For drivers, the painted bands carry no performance meaning and are simply a factory convention.
