An aggressive yet well rounded downhill and gravity tire with well spaced partially hollow and siped tall knobs for extreme grip. ATC - Optimized for enduro and trail riding the Advanced Trail Casing (ATC) uses a layer of SCT on the sidewalls and a K-Armor belt under the tread area. EN-DTC - With shore A values lower than the original DTC the EN-DTC provides a more responsive ride letting the knobs do the work of control and braking on the ground while also wearing better than similar tires. TLR/TR - Tubeless (Light) Race is the lightest tubeless ready version of tires Kenda offers and also features an improved bead shape for better retention
