A smaller tire has a much smaller l/r ratio, making it able to withstand the higher PSI. A larger tire has doesnt need or cant hold much pressure because of the increased surface area meaning less stress per sq in. Using a big tire with high pressure will tear the tire apart because the pressure will tear rubber and steel belt reinforcement apart.
For example: it is easier to break a long pencil as opposed to a short one.
