How unaware/clueless of your enviroment do you have to be to not notice you're driving on flat tires.

Kudos to you for the friendly warning.
People don't realize that for every 10 degrees in air temperature change they lose or gain 1 pound of tire pressure.

With these wild swings lately, your are better off riding a bit high than low. Set your pressure when its about 30 or 40, not 60, at least until we stabilize a bit. Another thing to consider when filling your tires is that you are supposed to set them cold, which realy means after a 2-3 hour period sitting, first thing in the AM if you can.
But since most folks dont have the means to fill their tires at home, they drive to the gas station. Even 2-3 miles can raise your tires temps enough to raise the pressure 2-4 psi. So, if you stop at Sheetz on the way to work, and have driven 4 miles to get there, you are seeing a number thats artificially high, and should adjust for that. If your pressure is suposed to be 32 cold, and you see 32 after a four mile ride, then your cold temp is 3-4 psi lower than what you see. Which means your hot temp is lower than it should be. And that means you are not getting the mpg you should, at the least.
Another note, if you have cool green valve stem caps, and think this doesnt apply to you, think again. Nitrogen expands and contracts with temp like any other gas. check your pressure, and add some good old air.

I did mention it was a female lol. It was on the passenger rear tire.
Barf. No.Did you blow her up?

30 psi in the front. 26-28 in the back is a comfortable ride in passenger cars; if you don't haul or tow. With all the "winter damage" to the roads around here; check at least once a month to be safe/sure. JMO

The correct answer is on the sticker in the door jam of the drivers door.
Violate those pressures and you could be the next Ford Explorer.

or you could follow the guidelines for the vehicle (with OEM tires). Use the information on the sidewalls if you've changed brands/size/style.
Generally, harder tires have less rolling resistance so bumping your preassure from 30 to 34 psi all the way around will improve your gas milage
I don't much care for a mushy suspension with vague feedback

Read the tire. My camry requires 40psi.

Mine require 40psi also. Max recommended is 50psi I think.
Thinner sidewalled tires are effected more by low tire pressures.

Damn, they sold you one with a working accelerator pedal.

110,000K miles and not one issue. Oil & air filter changes are all I've done.Damn, they sold you one with a working accelerator pedal.

Isn't that all of them?

The pressures on those stickers is the maximum pressure; let's say 32 psi, for example.
To fill a tire to that precise amount, makes you wind up rolling on "boulders when the tires heat up and the air expands.
One way to keep the pressures as I recommended, is to check and fill the tires when they are cold. Then, after driving a bit; check the pressures again. This will establish a baseline upon which to "experiment" with tire pressures that are comfortable yet safe, depending on one's own comfort level. Trust me.

if you will
In my experience, recommended pressures are found on the door jamb, and "maximum" pressure is on the sidewall.

And the recommended pressures are taken cold, not low and then they heat up.
DKP is running constantly under-inflated tires. Excessive wear, sloppy turn control, loss of MPG.....

Folks, please, do NOT follow this advice. Measure your cold pressure, true, and set what your door jamb says to, if you are on stock sized tires. Most cases, actually, stock pressures are a bit lower than they could be, in the name of ride comfort. And pressure rise due to riding is factored in by the factory guys, trust me. Do not go below the factory recommended pressure. Hell, in my car, which recommends 32 from the factory, 27 is the trigger point for the pressure warning.
Now, if you run upsized tires, like I do, you will have to figure out whats best. I ran factory pressure in one set, wear pattern got very odd, worn in the center, great on the outside. Upped that to 36 cold, wear evened right out. Now I run a 275/40/20 instead of the 255/45/20s that were stock. I go through one set a year, so my 2006 has worn out 5 sets of tires in thosse 110,000 miles, that gives a me lot of experience, with there being four kinds in that mix. I can see my tire pressure real time as I drive, sort of cool to watch.
Oh, and why should you listen to my trust me, vs the above trust me? Because our community has regular online chats with the engineers who built our cars, and we have talked about this subject.
