Competent fat bike treads for most conditions
Skip to view product specifications

The Mammoth bears more than a passing resemblance to the classic Maxxis Ardent but the tread pattern has been modified and widened to meet the requirements of the fat bike contingent.


The low, tightly spaced central tread means good rolling speed for a fat bike tyre, while the higher, softer shoulder knobs offer plenty of traction when you start to lean the bike over. Weight wise, the 1,300g Mammoth is competitive with other similar width tyres despite being one of the more puncture resistant fatbike options we’ve tried – the EXO Protection carcass wards off flats even at low pressures on rocky terrain.


Hit the inevitable wet patch and, thanks in part to the relatively open tread pattern, grip doesn’t suffer too much and mud is shed quickly. Run at 8psi, the supple 120tpi casing wraps itself over and around trail obstacles to maintain traction even on wet days in the hills.
