• The tyre is a 23-622 or 700-32C and the rim is 700C. At 80PSI (at the lower range) the bead still shouldnt slip off

    And is the rim suited to 32C tyres? Just checking - not familiar with those rims.

    No, 80 psi is not going to blow the tyre off but I was thinking that too low a pressure might allow too much movement of the tyre when riding.
