Pumping up your tires to at least the max sidewall rating not only improves handling on wet and dry pavement but also increases MPG by decreasing rolling resistance, and increases the life of your tires by producing a much more even tread wear pattern. As an example I run my RE92's at 60 PSI for most of the year, dropping them to 44 PSI (which is the max sidewall) in snowy conditions.

Last night I was doing 110 MPH, that means... 225% more fuel !!!! well it was fun tough...

60 PSI ???? that's like twice the recommended pressure for the car!!
So it's Toyota recommending low tire pressures for us to get bad MPG ??
