Poor gas mileage problem easily solved. D'oh!

Re: Poor gas mileage problem easily solved. D'oh!
I had my Michies set for 36psi in mid June. I checked a week ago and they had fallen to 32-33psi across all 4 tires. No one has touched them but me. I suspect cooler temps and a bit of normal escape were the cause. The overnight temps around here have fallen off from around 20C (70F) to near 10C (50F). We'll be into freezing overnight temps in another 6-8 weeks so that's about when I'll try to remember to check them again. The first TCH winter cometh, it will be interesting to see new winter related threads start appearing on this forum.

It would be interesting to correlate higher tire pressure with the specific tires (Michelin vs. Bridgestone) for each person that is doing this.

At 40+ PSI, I got 44 MPG on my trip this week from San Diego to LA and back (about 240 miles, including errands), according to the instantaneous readout. Speed was 65-70 MPH, with A/C running in ECO mode 100% of the time. Now, we'll see how city driving and short trips will ding me during the rest of this tank!

I've been steadily increasing my mileage with each tank. First one was 36.4 and when I filled up yesterday my last one was 43.5. At the same time I increased my tire pressure from 32 to 40 psi. My current tank is 46.2, but with less than 50 miles it's way too soon to say what, if any benefit I'll get.
