For me, I think it is unsafe to inflate my car over 39-40psi. The sidewall maximum pressure of my tires (Yokohama Avid TRZ 185/60TR15) is 44psi -- but I find that I start losing wet (and dry) traction if I go above 39psi.

I believe the recommended pressure is only 32psi, and it seems like anything between 36 and 39 is virtually the same rolling resistance; judding by my coasting distances and MPG.
Sincerely, Neil
