1986 345 AS MH Front Air Bags

[Jim Tyrney]

From what I can find on the recommended pressure for the front air bags on a 1986 345, it is 55 lbs. I checked mine yesterday and found 45 lbs. and seems to ride OK. What seems to be the consenus, 55 lbs. as recommended or some other pressure from experience? Thanks for any feedback. Jim

Jim,

55 is the recommended pressure for proper alignment. If the rig was aligned with 45 in the bags and you like the ride then you have no worries. If the bags were at 55 and the rig was aligned then you may start to show wear on the inside edge of the tire and you steering may not be as stable as you would want. The visual check is the tires. The ride/steering check is by the seat of your pants.

Brett, I just replaced the tires and I'm trying to find a GOOD shop for alignment, although, it tracks very good now with 75 lbs. in the front tires and 70 lbs. in the rear ones with 45 lbs. in the bags. Does the alignment conform to the P30 chassis or an Airstream recommendation? If the alignment checks out good, I guess I should raise to 55 lbs. and have rechecked while at the alignment shop to see if it makes a difference or just align with 55 lbs. Decisions, decisions!!!!! In the long run, you are right about tracking tire wear. Hope to hear more input. Thanks, Jim
