Tire Inflation & Rider Weight

[ny biker]

I came up with 99 from the equation, but I've been inflating my 700x23 tires to the max of 120 psi for several years now with no problems, and I prefer them with max pressure. When I has the Vittoria Open Corso tires, I inflated them to 130 which I think might have been below the max.

I can't remember who but it was someone here who said that the max inflation printed on tire is the result of an argument between the marketing people (who want a higher number there because the racers willing to pay $$$ for tires want to put 140 psi in there) and the legal people (who don't want to be sued because people see their tires poppin' off their rims when they're too inflated).

Made a lot of sense.
