Have you guys noticed that other than the AR56, most other rims on the LB page are now rated to a max of 60psi for hooked/50psi for tubeless?

That seems absurdly low to me. For a tire with a 28mm WAM, my optimal pressure is in the 80f/85r range for good tarmac - and that kinda dovetails with what Silca's tire pressure calculator says (which, in turn, is based on their extensive reach on total rolling efficiency, ie combining RR and vibration losses). Similarly, for a 32mm WAM tire, my optimal pressure is in the 65-70psi range. All tubeless, FWIW.

They said this was due to a tire blowing off the rim. What wasnt very clear was the circumstances which led to this -was it too narrow a tire (eg, 23 or 25mm mounted on a 25mm ID rim) or something else.

Leaving aside the argument of whether I SHOULD be riding at 65-70psi with 32mms, what do you guys think? LB is being absurdly conservative or would you not take the chance?
