I have only anecdotal evidence, but that evidence is available to review in the Garage. I have over 39,000 hypermiles between my two cars--with some 44 psi tires pumped to 51 psi and some 51 psi tires pumped up to 51 psi. I've now replaced four of those tires, and all four had perfectly even wear. This is in mountain and freeway driving, in the dry, rain and snow, and from 20 degrees F to 105 degrees F. I've had zero tire failures.
I recently picked up a pair of used 44 psi tires for the Clunker because of finances. They have a lot of tread left, but one was patched because of a nail. Those I keep at 40-42 psi to be safe.
