Okay, my car seems like it hasn't been getting that great of milleage lately, so I've checked the pressure in the tires.
The smart alecks at the oil change place love to fill them low, at around 32 pounds. I think they think they're making life easy on themselves or doing the world a favor.
So, I took it to the tire place, and the guy recommends 35 pounds, but I explained I want to get the max for the best mileage possible.
He looks on the tires and it says 44 pounds, so he says he'll do that, but neither he nor the manager seemed to know anything, saying that "we'll do this if you want to do."
So I'm stlll not sure. I've heard that overinflating can hurt under carraige parts. Will 44 pounds be okay?
I hope that someone here knows more than the nerds at the tire place, thanks.

35-40lbs is where you should have them. Over inflating and under inflated tires can lead to problems with the tire and can cause failure the tire recommends 44lbs but I'd keep it at 40 and have it checked every week

Too high of a pressure will cause premature wear on your tires.
There should be a decal either on the edge of the door or the door pillar of the driver's side door, (although older vehicles had this decal on the passenger side door) This decal tells the recommended tire pressure for your vehicle depending on the tire size that was originally installed on your car. They typically have anywhere between 30-35 psi as the recommended level. If you cannot find a decal on your car, then you will need to check the owner's manual. If you don't have an owner's manual, buy one from eBay or the dealership.
You shouldn't need 44psi in your tires unless you plan on carrying concrete blocks (or something else heavy) in the back of your car.
The pressure on the side of the tire is the MAXIMUM rating for that tire, and should only be approached if the vehicle that tire is mounted on is going to be hauling a lot of weight, or for towing purposes.
Hope this helps and good luck!
P.S., also realize that as the temperature of your tire changes, due to sitting in the sun or driving long distances, the pressure in your tire will change as well.

Check your owners manual first. It should list proper tire pressure for your make and model.
Other things can be skewing your mileage. Are your filters new and unclogged? Have you been keeping up with your recommended tune up's and belt changes? Are you using the recommended gasoline? Are you driving in more stop and go traffic lately? Are you carrying more weight in the car?
Just some other things to consider.
It sounds like you regularly take your car in for maintenance, but I know for a fact that some places aren't exactly honest. My ex husband worked at two well known national brand oil change shops for years and you would die if you knew what went on there. They frequently didn't actually put in a new oil filter and often showed the customer a new air filter and then just dusted off the old one and reinserted it. I know not all places are like that, but there are a few out there trying to make a buck off of trusting customers. I usually only go to my dealership beacuse I trust them, but thats just me.
Also, you could go to your dealership and ask specific questions of them about maximizing your mileage.

The recommended tire pressure for your vehicle is usually listed on the inside of the door. Depending on the maximum psi (noted on the tire), in your case 44psi is the maximum. The best for overall ride and tire wear is 35psi. Under-inflation will cause the tires to wear on the edges and a softer ride as over-inflation will cause the tires to wear in the center of the tread and cause a very hard ride.

The average pressure is about 35 psi. There should be some guide on the side of your tires. However, that is usually the lowest recommended pressure.
Be careful about putting too much air in your tires. They won't perform as well, can become unsafe, and will wear-out prematurly. That's right, too much air is as bad for your tires as not enough.

If the rating listed on the tires is lower than what's listed in your owner's manual, I'd go with the one on the tires. Otherwise, either follow the owner's manual, or follow the tires.
GENERALLY, it'll be between 35 and 45 in either case.
Overinflating could POTENTIALLY damage your suspension, because the tires dampen some of the impact, and the higher the pressure, the harder they are and the less they dampen. But I wouldn't worry about it too much.

follow the owners manual or look on the inside of your door or glovebox there should be a sticker in there that says what pressure you should run. also, over inflation or under inflation can cause other problems, premature tire wear, a blowout and so on, remember the Ford Explorer's and The Firestone Tire feasco

Tire pressure recommendations vary according to the vehicle they are on.
The same type & size tire on two different types of vehicles may have two different recommended pressure ratings.
Use the one recommended for your car.

32 is fine. You do not get much mileage by going higher.
