I received my 2002 Prius, which I bought in 2004 w front end damage, but that is another story, at 12k mi and indeed already half-worn tire edges from running 32 PSI all around. I pumped them to 45-47 PSI and then they started wearing evenly, so somewhere around 36k I needed new tires. Note that these tires had max inflation pressure of 51 PSI, so no problem with that pressure. Cor
