vittoria zaffiros have a 60tpi peabody

to the OP, max PSI also has to do with the type of tire and the strength of the sidewall because i've had older tires (on my mtb) where i neglected to follow the instructions on max psi and bubbles started to form in the side wall (steel bead, i think) which then render the tire useless.

example
vittoria rando's have a "low"er psi rating than gatorskins, and i personally attribute this to the strength of the side wall and the different use of each tire as randos are more so hybrid cross tires than road tires. and tubular wheels has like a 200+ psi rating.
