I have a 2002 Grand Am with factory ordered rims, not hubcaps. About how much air should be in the front and back tires? I'm asking because I noticed my back tire was leaking the other day, but this was because I had a missing valve cap. Any ideas on how many pounds of air should be in them? Thanks!

I know precisely how much air you need, no guesses or generalizations like the others.
The correct tire pressures for a 2002 Pontiac Grand Am whether it has the P225/50R16 91V or P215/60R15 93S sized tires is 30 psi front and rear. Over-inflation can upset the handling and braking performance of the vehicle, make the tires more prone to damage from road hazards, reduce ride quality and cause uneven tire wear. Under-inflation can cause many of the same things but can also cause tire failure due to stress as it is the air in the tire that carries the weight of the vehicle. Not enough air and the tire overheats.
You can find the correct inflation pressure information for your vehicle on the vehicle information tag inside the drivers door frame.

Look in the owners manual or the glove box door, or on a sticker on the door jamb or the inside of the trunk lid for the recommended tire pressures. You can also look at the sidewall of the tire for the maximum pressure. Running the tires with the pressure between the manufacturers recommendation and the maximum should do well for you. Running them with a little more than manufacturers pressure will get you better gas mileage and the tires will last longer because you are reducing the tire flex because of increased pressure. BUT.... you will notice that the ride of the car is a little more harsh because of the harder tires. For example...... if the maximum is 44psi and the manufacturer suggests 32psi.... I will run the tires at around 38psi..... a good compromise.

It is called a bead leak. Take it to the tire shop and let them fix it. They will dismount the tire and clean the rim and tire and then grease the rim with a leak sealant and remount the tire. The tire could also be deteriorated around the bead. The tire shop has to look.

I run 35 lbs. in my grand am GT tires and it helps on gas mileage. Just because your valve cap was off is no reason for your tire to be leaking, have it checked out.

the usual is 32 psi (presser per square inch). But it also depends on the size of the tire & rims. If you do not know how to check psi get a presser gage if you don't have one you can get them at auto zone or pept boys.

32 is the usual amount. Look in your owner's manual for the exact recommended amount. Also, check the side of the tire for the max pressure. Don't exceed that!

If they are high performance low sidewall tires then go with 40 psi. Otherwise 35 psi will do.

the recomended air for your tires is on the sticker in the door jam, it is there in almost all cars but people dont know it, for your car its most likely 30psi cold or 34-35 hot(cold is after it has sat for at least 8 hours and hot is after its been driven at least 1 mile)
