The big new buggers in WTB's DH line up, these are an all-round tread, but they work well enough in the wet to be worth putting in.
The multiple inline block tread holds sideways slides very impressively, and has a helpful habit of re-grabbing grip automatically on the front. The staggered design gives decent inline grip, too, and transition into turns is seamless, with buttressed side knobs handling side loads without squirming.
A super duty carcass with Inner Peace sidewalls keeps them stable and secure at low pressures and they suck up hits beautifully. They are, however, damn heavy.
