Do you mean EXO? I like ’em, roll reasonably fast and are decently grippy, though the tread’s not that deep and they wear a tad quickly as a result, maybe stick a Minion DHF 2.35 on the front – it’s actually a very slightly smaller tyre, but grippier in softer stuff – and an Ardent on the back. Not great for drive in really soft or muddy stuff, a pair of Minion DHFs f and r is probably a better all round combo if you encounter muddiness regularly. I’m running Minion (f) Ardent (r) over winter in the Peak and with it being gritty slurry rather than proper mud, it’s a pretty good all-round combo, grips on rocks, front reliable rear fast rolling and grippy enough mostly.
Id go for the EXOs if you’re either going to ride in rocky places or you’re planning on running them converted to tubeless. The standard sidewall’s quite thin feeling and the EXO adds a relatively small weight penalty.
