That is not only not true for bicycle tires, but it is absolutely not true for passenger car tires and here's proof:



This is a page from The Tire and Rim Association yearbook - the US tire standardizing organization. Notice that regardless of the width of the tire, the table ends at 35 psi (except for Extra Load tires).

Sorry that is not true either. Here's proof:

Not everything you find on the interwebz is true.
