Will a little flat tire (65 psi in a 90 PSI tire will probably feel and look flat) hurt any thing?
It wont look flat at all. As for the feeling, that depends on how much you ride with the acquired familiarity and are able to tell the difference. At 65psi you will have a comfortable ride.
Only the very high PSI racing tires have a prescribed minimum for safety and performance issues.
