I guess my question wasn't clear. What I am looking for is the pressure at which the tire is in danger of breaking the bead. I don't want to run at that pressure obviously.
As Mike mentioned, he's accidentally done some spirited ryding with pressures as low as 8psi while running his Hydro-Edge tires; & as well as doing tens of thousands of miles in 4 wheeled vehicles running tires at lower pressures, I've also done a few thousand miles of test track type riding at 10 Psi on Kumhos & a couple of other tire brands on Spyders, & that riding included some fairly tight turns at reasonably high speeds... repeatedly :shocked:; and neither of us feel we've even got close to rolling a tire off the rim... yet! That said, there's almost certainly going to be a fair bit of 'unconcious intervention' going on when anyone is riding hard or pushing close to their or their rides' limits.... you might not realise how much you are trying
not to turn too hard or push beyond the 'reasonably safe' feeling you are comfortable with, but it's definitely there & without conciously pushing beyond that, you aren't
too likely to reach the limits - besides, my days of actively trying to push thru those limits/boundaries & break things on purpose are well past!! :shocked:
And you can add to that how careful the Nanny is.... I reckon it would
really take some Posthumous Darwin Award level talent for anyone sane to push too much beyond the Nanny's usual intervention levels - still, I'm sure it
CAN be done, so please, don't take that as a challenge, but I think most sane people would realise pdq that they were pushing her limits & unless they seriously have a death wish, most will tend to back off once the yellow lights start flashing & she starts reducing power &/or applying the brakes on just one wheel to keep you in line!! And AFAIK, she can't/won't intervene in a way that makes rolling a tire off the rim any more likely once you are out there on the ragged edge - she's a pretty smart software package! :thumbup:
