    First week with the Prius and on this forum...so bear with me. I've been reading about the increased tire pressure used by many Prius drivers and followed suit with a 42/40 in my Michelin XRadials. Since I have 185 pounds of extra battery in the back with the Hymotion...should I modify this formula to compensate at all? The Michelins are rated at 44 psi max sidewall pressure.

    Whatcha think?
