That assumes they are constructed the same - and clearly they aren't.
Bicycle tires are specified to run at much higher pressures than passenger car tires - as are medium duty truck tires (over 100 psi). This has to do with the strength of the materials in the sidewall.
Heck, the tires on the space shuttle are inflated to over 300 psi.
