I run 39 psi cold and that seems to work well. 38 psi is what is on sticker on door jamb. I don't like over inflated tires I think it does ride harsh.
i run 42 psi cold and when they heat up im at 44. i want hot 44 since it gives me a more responsive feel.
Looking at Fuelly, it appears I run 40psi in the winters, and 46 psi in the FuelMaxes.
That's what I keep mine at. It seems to be a nice balance for MPG and handling.Interesting thread. I have thought about this a good bit but haven't done a whole lot of experimenting. Right now I am at 39 cold IIRC. I see 41-42 PSI on the highway. Seems to be a good balance of ride, handling and fuel economy. I may bump that up a lb or 2.
