Continental Rain King DH 26x2.5 Tire: When the roots are slick, and the muds deep, roll on the wet-weather-friendly Continental Rain King DH Mountain Bike Tire. The rain-specific Black Chili rubber compound hooks up when other tires cause you to take an earth bath. The Rain Kings tread pattern bites into soft ground, and its wide spacing sheds mud, while staggered side knobs give you the confidence to brake late and corner hard.
