It's sometimes called "tread splice." It's a fairly common occurrence with the Rivals and it's purely cosmetic. It won't really develop any further and doesn't affect the performance or longevity of the tires. BFG is aware of it, it came up when they were first released, and at this point they won't replace tires because of it.
