Whats the standard tire pressure - 2005 Chrysler Pacifica

because it is a low profile tire with a wide tread , the 30 psi is a recommended pressure for a standard size tire
however at 30 psi you will probably find that it will wear with an under inflated wear pattern and the 40 psi is used to sit the tread flat on the road
best talk with a good tire shop as they have experience and reports form a vast range of customers who talk about the pressures they run to get the best wear from the tires
the tires I run are standard and the recommended pressure is 32 psi but the make of tire actually runs best on 38 psi and that comes from the tire manufacturer

There should be a sticker on the door (near the latch) that gives your tire info (size and pressure)
If you bought a different kind of tire than what's standard, it is possible that they require that much pressure (it will list max pressure hot/cold right on the sidewall). If they are indeed rated that high, then defer to the tire manufacturers recommended pressure. If the ride is very harsh, you can go below that by about five pounds and still be OK.

35 Psi. is pretty much standard, but you can look at the tire inflation label inside the drivers door. It may be on the edge of the door or on the post inside the door.

The vehicle specifics are located insde the driver side door jam. Look for a sticker. If not, look for the tire pressure ratings and pressure specifics on the tire(s).

A car that size I would run 32 psi that is pretty much standard tire pressure for any car. 28 seems a little low to me. Air them up to 32 psi. If you know your alignment is good check the tire wear and see if they are wearing even and adjust tire pressure from there. If the middle is wearing and not the sides lower it.

It depends on the tire manufacturer. Generally speaking for standard tires and standard driving style I would keep the pressure somewhere in between 30-32. Try to balance similar pressure between tires to equilibrate driving.

Do not go crazy with that, current wheater and long driving will modify the current pressure in the tires. Just try to avoid significant deviations to specs.
Hope it will help

Standard 87 octane is all that car requires. You will gain no benefit from using mid or top grade fuel.

Most passenger car tires are run between 32 and 35 psi, regardless of season. You can look at the side of the tire to find what the max cold psi pressure is. You will normally find that it is 35psi.

As for summer/winter tires. If the wobble only happens when the snow tires are installed, and not with the summer tires, that obviously eliminates the car as being the problem. Do you have your summer and winter tires mounted on different sets of wheels, or do you swap the tires every season on the same wheels?

If they are on different sets of wheels, then the winter tires are out of balance, have some sort of damage to the carcass of the tires, or you have a bent wheel. If you are using the same wheels and swapping the tires every season, then you need to have your winter tires balanced and see if it solves the problem.

not really it standard on that car,32 psi. some car makers list 28psi. but ive found 32psi to be good.hope this helps.

35psi is the correct pressure.

To reset the tire pressure monitor system, after correcting the problem, you have to use the options under the Driver Information Center (DIC) on your dash. The button you want to utilize is called the "set/reset" button, it is the third button from the left, directly in the middle of all the buttons. It has an arrow that points to the left. Press and hold the button until the DIC displays "Tire Inflation Has Been Set", this message confirms the tire pressure system has been reset. If, by chance, the DIC does not return to the standard display with the date, ect., you can press the "options" button to get back to the standard display. The "options" button is directly to the right of the "set/reset" button you just got done using. It has a lower case "i" on it.

check the max pressure rating on your tires. Itill be hard to see but you will find it around the beed near the tire size. I would put them about 5 psi lower than the max rating to be safe. I would gess somewear around 35 to 45 psi.
