So it is. Wonder when my memory slipped by 1 PSI? I suppose its a good thing I fill them to just above the mark.
Regardless, I get at least the advertised mileage. My experience is that the trip meter reads about 1.5 to 2 mpg low: The last four weekly trips are 51.1, 47.7, 47.23, and 47.2 mpg.
I run at 40psi. I only have 3k miles on my Accord Hybrid, but had 250K on my prior Civic Hybrid.
My experience with the Civic Hybrid was significantly better gas mileage when running 40psi vs. 33psi (1-2 mpg) and decent tire wear (no observed difference).
Hard to say if there was any impact on handling given the lack of HP in the car (though my experience with sports cars, a little more psi/stiffer sidewalls actually improves handling - probably not a factor on these cars).
Totally agree, 40psi will ride harsher than 33psi.
I am intrigued by the comment about the trip meter showing 1.5 to 2 mpg low.
My Accord is consistently overstating gas mileage by 1.5mpg. Maybe the computer is incorrectly calibrated?
BTW: averaging 45-48 actual MPG, expecting it to get better as the temperature warms up.
