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
