It seems to be a common practice here to over inflate the tires (above Toyota spec but below sidewall max that is) to get better MPGs. Has anyone noticed any early deterioration of suspension components? If yes, what kind and how high of PSI? I used to run my Camry at 40PSI. I still had all original suspension components when the car got totaled at 160K. I am just wondering if the Prius' suspension is any weaker, due to weight saving and what-nots. I am currently running 44/42 with 17 Five tires.
