Is there a way to adjust the air pressure on the tag axle of my 1998 Newmar Kountry Star Gas RV? I filled up at a truck stop and then weighed it and the slip showed that the tag axle weighed 5500 lbs. It is rated at 4000 lbs I think. The drive axle weighed 8440 and it's rated at 11000. I was thinking that if I could reduce the air pressure on the tag axle, I would transfer some of that weight onto the drive axle. I don't have any water in the RV and the holding tanks are empty. I just had a washer/dryer installed, but according to the Splendide website, it only weighs 150 lbs. I think the empty rear end of the coach is putting that weight on the tag axle. Does anyone know if the air pressure is adjustable?

You should have what looks like a tire valve near a rear fender or out back near number plate one for each bag. You should be able to release the air from these valves. If you can't find you may have to crawl under coach an follow air tubes from top of bags to locate.

I do have those valves but my tag axle is pumped up by an electric pump located in one of the compartments underneath. If I let air out of the valve, won't the pump just pump it back in? Do you know if there is an adjustment to cause the pump to not put so much pressure in the air bags?

Thanks for yor reply.

You may have a gage an relief valve near dash to control your air pressure or the same near your pump. The pump should have some info on it indecating pressure set. Is there a tee from pump to both bags OR do the bags each have a electric control valve? There must be a control some place that you haven't found yet. You can call Newmar repair center give them your coach # so they can look up the type tagaxel you have.
