For drivers of light trucks, SUVs, and crossovers who want all-season traction and the peace of mind of run-flat technology, there's the Bridgestone Dueler H/L 400 RFT. The Dueler H/L 400 RFT features a tread pattern of longitudinal and lateral grooves plus sipes for year-round grip (and is M+S rated for mud/snow traction), with an advanced, long-wearing rubber compound. Its run-flat technology allows a driver to keep going as far as another 50 miles even in the event of complete loss of inflation pressure. Additionally, the Dueler H/L 400 RFT is used as original equipment on select vehicles from Toyota, Audi, Mazda, and Mercedes-Benz.
