When Zipp introduced their Tangente line of tires in 2007 they did it with a focus on leading edge airflow properties and how they interfaced with their rims. They worked with an industry-leading manufacturer to develop the tire casing and tread compound, but did not have as heavy of a focus on rolling resistance.
For the Tangente SL Speed tubular tires, Zipp has taken everything they learned from Firecrest rim shapes and updated their tire technology to not only maximize airflow, but also optimize rolling resistance.
