The Kumho Ecsta STX delivers the trifecta of performance for your pickup, crossover, or SUV: Excellent year-round traction, a smooth, quiet ride, and sporty good looks. The tread pattern channels water away from the tread, helping to prevent hydroplaning, while the tire’s construction provides responsive steering and high-speed durability.
