I'm aware that the M+ I run on the front of the SMGTe is a little skittish. I put this down to it wearing unevenly around its cross section (it has many, many, many miles on it) and the choice of compound Schwalbe use. My fast bikes use Durano (or Durano Plus) tyres, and they have a quite unsettling sudden grip failure in certain types of wet. Tends not to be a problem, but it does make for lively braking / turning at times.
When its pumped up to a decent pressure, I can feel the M+ change behaviour as I tip the bike into a turn (away from the normal contact patch and towards the side wall). If its running low on pressure, the change in grip characteristic and radius gets compounded by the tyre squirming to handle the corner. If its wet, then the deformation also sees you swing wider in the turn.
It sounds scary, but to be honest, I just dial it out by turning low and hard, pitching the bike over to the point that I know I'm assuredly off the ridge.
