Kenda don't do a full downhill mud tyre, but this is a great 4X option. The spiked tread is the most dramatic here, with ranks of 4mm high hexagonal shoulder knobs, then just a handful down the centre line. This means it bites very deep in slop, nails wet grass and hangs on crazily in off-camber or 'cranked right over' situations.
It also clears heavy mud fast for a spiked tyre and the tall knobs, and nearer 2.3 than 2.1in carcass, provide reasonable pinch flat protection for the mid-range weight.
The tyre really lurches onto the outer edge though, which takes some getting used to, and the lack of centre tread means it slides or spins very easily when upright on wet rocks or roots.
Can't fault the price though.
