Double down on durability.

While its EXO sibling may be a little bit lighter, the Maxxis Aggressor Double Down/TR 27.5in Tire is in it for the rough and gnarly with a reinforced casing that'll increase your chances of getting through the day flat-free. Maxxis' Double Down dual-ply casing construction provides slightly heavier, downhill-inspired protection than EXO and boasts a TPI of 120 compared to the EXO's 60. While this does add a bit of weight, clocking in just a hair over 1000 grams, Double Down makes up for the extra grams with increased durability to weather the miles.

The knobby tread design boasts hard edges and reinforced side knobs to grip through loose, unpredictable stretches of trail and keep you from washing out on tight corners. Take the Aggressors on smooth hardpack and they'll do just fine, but you'll really see them shine on the loosest, least consistent sections of trail.
