Thanks for the find. He does great testing and this is a great test. I agree. But even he was not willing to call the results definitive: "there obviously aren't enough data points to call these results representative. They're not rigorous tests (thus the "snapshot" title)."
I have no evidence to challenge the claim that more than 50psi on a 44 max sidewall tire is better. I originally boosted to 60 to follow the PaleCivic example. His tires were 60+psi and we all know the amazing results he used to get from his 1996 almost totally unmodified DX.

... So from this data and research, improvements can be seen up to 100 lb/in2 However at these inflation pressures I don't know if a cush air ride would even help a street car LOL  I doubt 100 lb/in2 would be safe for every day road use. But it is interesting test data none the less.
Hope some of you find it interesting.

That is interesting... but 100? Not for me.
