I have personally see better and more even tread wear with elevated pressure. At the specified pressure the shoulders wear down while there's still good tread in the center. At sidewall max 51 psi, even wear across the entire width for the whole life of the tires. Running at the lower pressure means I have to replace the tires sooner, so higher pressure is actually saving me money on tires as well as gas.

I have seen this on multiple vehicles and several brands and models of tires.
