Recommended air ride PSI front and back.

Thanks in advance for the help! I'm traveling back from California to Colorado and currently in Las Vegas. My air ride suspension has a slow leek in the back and I think it might be coming from the compressor. I probably need to have the seals etc replaced. I'm having to stop every two days or so to air my bags back up. I'm currently running 80 psi in the front and 100 in the back. What are is the max it can hold? We are carrying a lot of extra weight because we are moving some thing back.

Update: She's in the shop loosing about 5lbs in the back per day and they are having no luck locating the leak with soapy water. I think they have checked the compressor for a leak as well. Unfortunately it could be a slow leak in a hard to reach area but they will be back on it on Monday.

55 front and ~100 for the rear.
Your compressor should take care of it with a slow leak like that?
There is supposed to be a 1 way check valve keeping the system from leaking back out of the compressor. Some people install more than 1 check valve in the system, like i.e. you could have one to keep the bags at 100 at all times and one at the compressor.

She's in the shop now and they are trying to diagnose the problem. I'll mention the check valve for sure. If left for long she looses most all of the air and then it takes forever for the on board compressor to build it back up. I think its also only strong enough to take the bags up to 50lbs or so in the back. The fronts are a manual fill and seem to be holding ok.

Thanks Peter and I'll keep you informed as soon as info comes in.

So I got a call from the shop today. The leak is not obvious but it definitely has one at around 5lbs a day. It could be a line that is not visual or it could be a slow leak from the old bags. The recomendation is a new Firestone kit without the compressor. I'm looking at about $450.00 for the Kit and $400.00 in labor. I think I'll give them the green light but before I do I'm going to make sure the compressor is adequate and the front bags look good as well.
