DESCRIPTION

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.

  • Circumferential and lateral tread grooves evacuate water to help prevent hydroplaning
  • Large, stable tread blocks for a solid footprint and responsive steering, even in nasty weather
  • Variable pitch tread blocks reduce road noise for a quiet, comfortable ride
  • Rim protector protects wheels from curb damage
