I have no data but I would assume it is the same as car tires : more pressure => lower temperature => less wear
But the issue is not straight line, it's the bends and there, your smaller contact patch is asking for troubles.
If you have really short lasting tires it's because they are of a softer compound and that you don't hang around ...
Are you using twin compound tires with soft on the sides and hard on the middle ?
Finally, I bet you expected such an answer on this particular website but if you're concerned about tire longevity, quit accelerating briskly ...
