Tire pressures

yeah it's supposed to be at 33psi....I noticed the same thing a couple of weeks ago when my TP light came on. I checked all around, and they were right around 42psi, except for my right rear that was at 27psi.
I changed them all to 33psi, was fine for about 300 miles...then my TP light comes back on again.

I run 34psi all around with the OEM Bridgestone Potenza 050s. Mileage may be slightly affected by tire pressure, but most likely its those 306 horses and the tendency for us especially "S" drivers to have a lively foot.
Tire pressure has been steady on my G, which is 11 months old with 12K miles on it. I get 16.9 MPG with a mix of city and highway driving. About 15 in pure city driving and 23-4 on the highway

I'd recommend 35 psi for max fuel economy, 30 psi for max comfort and traction.
41 is way too high. Most oil lube places, etc. don't even check the pressure, they just fill the tires up and guess.
I remember when I got drag radials put on my last car (recommended pressure 25 psi). I drove home and had worse traction than with my bald street tires. I checked the pressure, sure enough, 45 psi. I was driving on balloons.

isn't higher tire pressure supposed to help give better gas mileage?

Overinflating your tires hurts traction and can increase tire wear.
Think about riding around on a bicycle with flat tires vs. inflated ones.
Once they're inflated properly, adding more pressure doesn't make a difference.
My TP light didn't come on till I had one tire at 25 psi (digital checker).

Actually overinflating tires probably does help gas mileage, as it will decrease the tire's footprint and thus rolling resistance. It will also (significantly overfilled) kill traction and greatly increase tire wear. On my road bikes BTW, the tires get inflated to 110 PSI, and you can feel the rolling resistance decrease for every ten pounds or so of pressure.
You're right that tires should be measured cold, without having driven on them that for a few hours.

Yes We Can....!
currently I have 41 psi in front tires and 34 at rear
There's an easy solution to your question, Owners Manual and on the drivers
side door jam it will tell you exactly how much pressure the factory recommends running in your tires. Any thing else will result in tire damage or
loss of gas mileage....see that wasn't difficult!
