What does the inflation chart call for with your weights?

Your front axle carries 18,000#'s? I know Newmars are heavy but, have you weighed the rig to know for sure what pressure is required?

Without individual wheel weights we would all be guessing.

It's essential to weigh each wheel to be able to determine tire pressures from the charts.

Until the weights are known, then keeping the high inflation pressure is prudent to prevent overheating/damaging a tire.

I agree error on the high side. Most "blow outs" are due to under inflation.

Greg,
The data sheet on our 2011 is 120 PSI on drive wheels and 85 PSI on drive and tag axel works well for us.
