Retreaded Tire Communication Device Placement Around Belt Edges

The patent positions the communication device in a specific three-dimensional location within the tire structure - radially inward from the groove bottom but outward from the innermost belt layer, and outward from the minimum width belt layer in the width direction. This spatial arrangement ensures the device remains accessible while being protected from retreading operations that remove only the outer tread portion.

The patent creates a localized protected zone for the communication device by positioning it at specific radial and width-wise distances from belt layers. This local quality approach ensures the device is protected only where necessary (deep enough to avoid retreading damage) while remaining accessible in other dimensions (outward from minimum width belt layer for maintainability).

The patent extracts the communication device from the area under the belt by positioning it outward from the minimum width belt layer in the width direction. This extraction eliminates the need for complex belt modifications or additional protective structures, as the device is protected by its strategic position relative to the belt edges rather than being embedded beneath the belt structure.

The patent performs preliminary positioning of the communication device during tire manufacturing, placing it at predetermined radial and width-wise distances from the belt layers. This preliminary action ensures the device is in the optimal protected position before retreading occurs, allowing it to survive the retreading process and maintain long-term service life while remaining accessible.
