advantage 2.1 70a makes a great rear and should last a while (70a is quite sticky too surprisingly, not hard at all).. you should also find it rolls a fair bit better than a Nevegal. i only really rate the Nevegal as a front tyre weirdly; can’t comment vs BlueGroove never tried it. similarly (or opposite), Advantage is not a good front tyre imho, can wash out at some angles, scary! Minion 60a 2.35 is about the best front tyre in general imho.
if you only ride trail centres you can probably get away with a fair bit less tread than any of these though.. umm was going to recommend Schwalbe but they don’t last nearly as well as Maxxis.. try Nevegal front, Advantage rear? maybe Ardent front, Adv rear.. hard to say depends on your style eh. you don’t say your weight or rims either so hard to recommend sizes!.
Mud-X? They’re better for natural and soft stuff imho. XR4 looks like it might be a decent all rounder but don’t buy from allterraincycles.co.uk …
