ITP – Blackwater Evolution Tires, including 8-ply radial mud tires in 26, 27, 28, 30 and 32 inch ATV and UTV fitments. The Blackwater Evolution is ITP's radial mud tire for riders who spend real time in the slop but still have to ride home. The radial casing lets the tread stay flat on the ground instead of ballooning, so the deep, self-cleaning lug pattern keeps biting into mud, clay and standing water while the sidewall soaks up trail chatter. Eight-ply-rated construction with a heavy sidewall is what makes these hold up on rock edges and stumps that shred lighter mud tires, and it is why they work on heavy side-by-sides as well as big-bore quads. Wide spacing between the lugs throws packed mud clear as the wheel spins, so traction comes back the moment you get moving again. Because it is a radial, the Blackwater Evolution also runs quieter and smoother on hardpack and gravel than a bias mud tire of the same size, which matters when the ride out is twenty miles of two-track. Match your diameter to the machine and keep front and rear staggered widths in mind, and pair them with beadlock wheels if you air down for extra grip.
