Air shocks stay fully pressurized an won't adjust for normal ride
I had new tires put on my 2002 Pontiac Montana and now the air shocks stay fully pressurized. Raising the rear end to the maximium. If I unhook an air line at the shock the pressure drains off and after I hook it back up, in not much time they are fully pressurized again. Is there a way to reset this system so that it works properly. The tire company was baffeled by this. I think that the air system should have been turned off when the car was raised.

Which computer are you wanting to reset? There are at least 5 on your vehicle. The next question is WHY do you want to reset it? Are you trying to clear fault codes or are you wanting to clear adaptive learning stategies? or BOTH? Are you having a problem with warning lights coming on? If so, have the problems been corrected that CAUSED the lights to come on?
Anyway, a scan tool is required to reset ANY of the computers on your vehicle.
Tire centers tend to over inflate tires. You probably have become accustomed to a softer ride. Try lowering tire pressures a couple of PSI but be careful, to low a pressure will affect handling. The factory tire pressures are in your drivers door sticker.
32 psi is the usualrecommended pressure but you may have to fill the tires to 35 psi to make the TPM system reset. That's how most systems recognize that you have serviced the tires. Most TPM systems will indicate low tire pressure around 26-28 psi.
depends on the options some had 15 or 16"
open the drivers door there will be a sped lable on the inside the door edge has recomended tire size, air pressure and so on
also the size is on the side wall of the tire
hope this helps
