Lower, as most computers are actually measuring rpm and for a constant linear speed rpms decreas as diameter increases. However, the difference is probably marginal at best.

I don't have a fancy computer or anything, but when my tires are around 10lbs lower than they're supposed to be, I can definitely tell a huge difference. Not so much in speed, but in the effort it takes to maintain speed.

I roll Specialized Nimbus 26x1.5 at 85psi. They are rated for 50-80, I believe, so I am cheating a bit, but they have been fine. I notice a big difference when they are down 10psi, but I am also a clyde, so there is weight involved.
