It probably depends some on the tire brand and model. Insight owners have been very successful running 80 psi in the Bridgestone RE-92. There are lots of examples, with no recorded examples of damage, that I am aware of. I do suspect that damage would be more likely with old tires.
However, the gains in MPG at 60psi+ are very small if any. The Insight is a very difficult car on which to make such measurements, so it is a bit difficult to really know
