The Continental Trail king is an aggressive all mountain tire. Its high volume and large, well spaced lugs lend themselves well to rocky, technical trails where grip is at a premium and rolling resistance is less of a consideration. The Trail King is made with Continental's Apex sidewall, which uses a strip of material above the bead for added stiffness. This allows for lower tire pressures. Continental's Black Chili compound reacts to surface irregularities more effectively to provide additional grip and lengthen tread life. By the numbers, Black Chili reduces rolling resistance by 20% while adding 30% more grip and improving tread life 5% over Continental's earlier generation tire compound.
