i have a 97 grand am gt (aluminum rims) its about 5 degrees in wisconsin, when i park on cement the pressure dropps REAL slow, about 24 hours to start looking low. but when i park on the grass it seems to drop over night... any suggestions??

WOW!!! That's bizarre. Have you considered throwing an air gauge at it to see if it is really different from the blunt concrete vs. the pointy blades of grass? You "look" smart but it is so hard to tell by "looking". A good air gauge should answer your question. If your tires do lose air in 24 hours get it fixed at a qualified facility.

Temperature certainly has a role to play on tire pressure, this is mainly due to air contraction as the temperature drops. As described by Tom, the reason for a faster tire pressure drop (overnight) on the grass could well mean that the grass area of contact has a lower temperature as compared to the cement area. In any case, the very first thing that you want to do is to pump more air into the tires, if the situation is still manageable. Then observe further (meanwhile, make sure that you do not make long distance trip or anything like that). If the situation did not improve, bring the car to a professional mechanic and get the problem resolves - do not take chances with low tire pressures.
Remember, tires are the only contacts between you and the road, respect that fact.

I'm just over the border in Minnesota and we are a lot colder than 5 degrees. Ever since it got REAAAAALLLLLYYYY cold last weekend the tire shop where I work has been bombarded with low and flat tires. Probably 75% of them are bead leaks - the seal between the bead of the tire and the rim is comprimised. These happen all the time but really cold weather can make them much worse. The tire needs to be dismounted to cure the problem. Take it in and have it repaired.

If it is just one tire, take it to have it fixed at a tire shop. It could be a slow leak around the bead. The uneven ground under the grass could exacerbate the problem, causing it to go flat more quickly. Also, as was said above, tire pressure varies with temperature. Make sure the temps were the same on both nights; you may just be seeing the difference between a 50F night and a 20F night.

the only thing that I could think of that would remotely make sence is that we all know that cold air will lower tire pressure and based on the info you gave is that the concrete is retaining some heat and is a higher temp than the grass, therefore the tire is not as cold and the pressure does not drop as much,I've never heard of this happening and it is hard to imagine it but its a possibility, either that or your dad is getting mad at you for parking in the grass and letting air out of your tires

yep, those three materials don't mix.Rubber, aluminum and road salt. Some moisture gets between the rim and tire and dries, the salt is causing it to develop a rust layer on your rims bead.Most tire shops can break down the tire and grind down the rust. Might even be a crack in the rim , small enough to allow the tire and rim to loose the seal.
Good Luck...

if you don't have a leak then the cold air alone makes the air in you tires shrink so to speak it slow down the movement of the air particles in your tire so it doesn't have as much pressure as if it were warm outside. To avoid this you can go to any tire shop and have them swap out your plain air and put in nitrogen. It is lighter than air and doesn't get affected by the weather like regualar air does. And you will feel a difference in the ride of your car as well. GOOD LUCK

seams as though you have a slow leak, may just be when you are parking in grass hole is on bottom allowing less air to escape.
take It to a tire shop & have them submerge your tire in water to check for a leak.

tire pressure drops with the weather

Check your tire valves, make sure the inside valve is tight..... other than that look for nails or something that is causing your leaks.
