Basically, too much weight at too low of a pressure. Higher pressure will blow the tire off the rim.That doesn't make sense to me, but maybe I am missing something. How much weight and how much pressure are you thinking of using with what sized tire? I don't see wanting or needing to run enough pressure to "blow the tire off the rim". At the lower pressure end of the scale I don't see going low enough for burping to be a problem.
Just trying to understand...
Tubeless psi hurts my brain, general rule of thumb max psi is as follows:
23mm - 116psi
28mm - 100psi
32mm - 45psi
So you see the pressure goes down as the tire gets wider. I don't have specs on 40mm (29x1.5). Stan's said max would be 40psi. At those low pressures, rider plus gear would make the tires roll poorly.
My Hutchinson tires arerated to 85 with a tube, 34mm width keeps me at 45 tubeless.
Hope that helps... Lol.
I can try and copy/paste the email from Stan's if you want more.
