Re: Tire load ratings and inflation - G vs H Reply #25 – May 06, 2019, 09:53:02 am Monaco also uses an easily adjustable pressure regulator to control PSI to the tag.Of course, a separate ride height valve for the tag axle could achieve the same thing, but there can be some down sides.

Re: Tire load ratings and inflation - G vs H Reply #27 – May 06, 2019, 11:03:43 am Don't see any adjustment. Would have to put a pressure regulator in lines 80 and 81. WAY past my pay grade to know all the pluses and minuses.James Triana at Foretravel or Aubrey Lee at MOT would be the best people to work with on any project like this. BUT, only worth it if percent of GAWR is way off between the three axles. Quote Selected

Re: Tire load ratings and inflation - G vs H Reply #30 – May 06, 2019, 11:34:43 am I am running about 90% gawr front, 85% drive, and 80% tag. If I put a 1500 lb motorcycle and lift on the back, would tag take most of weight, or would it be distributed between tag and drive? Quote Selected
Re: Tire load ratings and inflation - G vs H Reply #31 – May 06, 2019, 11:44:40 am If I recall the tag axle has a single air bag on each side and the drive axle has two air bags on each side. Assuming you are on level ground and all of the air bags are the same and at equal pressure and that the geometry of the tag axle puts the tires in uniform contact with the ground as the drive axle. Think this through...It would look like three legged stool at each end of the rear axle pair. Wouldn't the drive axle carry twice the load that the tag carries? And since the drive axle has two tires on each end and the tag only one wouldn't all three tires individually carry the same load? And if so they should all be inflated to the same PSI?I don't have a tag and have not seen weight measurements from one. Just trying to think it out. Quote Selected

Remember weight to back takes off the front, tag down force puts weight back on front. Now add ride height contol and we have all kinds of unknowns Quote Selected

Be a shame, welding on your $5000 Hydralift, loading up your full dresser and finding out your axles are overloaded. Quote Selected
