UPDATE:
Thanks for the advice guys, 2.35″ folding bead High Roller in 60a flavour now fitted and (so far) very happy.
A smidge bigger than a 2.1″ Nevegal, and it was a total PITA to fit tubeless (Stans). My Nevegals went up very easily in comparison, I wonder if it is because they were old/used. I managed it in the end, but only by using a very concentrated washing up liquid solution. I literally bellowed with relief when it went up.
One ride in and I am very happy. The tread is significantly more open than the Nevegal and it seems to be less affected by the mud. Cornering felt fine, didn’t really experience the transition from centre to side knobs apart from maybe once. The carcass seems more robust than the Kenda, to the point where for a given PSI it feels stiffer/less compliant – I may have to use less pressure with the HR. Does feel a tiny bit slower to me, but not a problem.
Overall: pleased, but wont know for sure until a couple of months down the line.
