The 2.5in version of the Maxxis Aggressor is noticeably rounder in profile than its 2.3in counterpart, making it more predictable when carving corners as well as more comfortable through the rough.
The DoubleDown casing offers great puncture protection and damping but it’s heavy. And despite the low-profile centre tread, this version was surprisingly mediocre in my rolling resistance tests, losing out to the Schwalbe Hans Dampf and Specialized Eliminator, perhaps because of that stiff casing.
The more fragile EXO casing version rolls faster, as well as being lighter and cheaper.
It’s no semi-slick though – there’s respectable traction especially over rocky chutes and hardpack. Lean it over into a loose turn and it bites with authority, and holds a line better than most rear tyres especially on loose, rather than sloppy, terrain.
But when things get greasy or muddy it slides sooner than most rear tyres with comparable rolling speed, especially under braking or on technical climbs.
Grip over wet rocks and roots isn’t great either, so it’s occasionally fidgety through these sections.
I could look past this if the rolling resistance was class-leading, but with this casing the rolling speed is only so-so according to my roll-down tests. This makes the comparative lack of grip seem like an unnecessary sacrifice when compared to the Schwalbe Hans Dampf, for example, which I found to be both faster and grippier.
- This tyre was tested as part of a group test. All tyres were tested back-to-back on the same tracks, keeping all other variables as consistent as possible to ensure our findings are as reliable and accurate as they can be.
