Designed for high-end sports sedans and crossovers, the Bridgestone Potenza S001 RFT features a silica-enhanced tread formulation for summer traction and long wear, water evacuating grooves to resist hydroplaning, and a tread pattern that's computer-tuned to keep road noise to a minimum. What's more, the Potenza S001 RFT features run-flat technology, enabling a driver to safely keep going for up to 50 miles at speeds of 50 MPH or less, even in the event of tire failure.
