OK... fair enough...then I look at the Goodyear chart from their tire guide, which I included...and I can't figure out how the weights from the Thor placard jive with the Goodyear guidance...help? The highlighted chars is my tire size 245/19.5


PS...I can't figure out how to show my pictures inline, not as an attachment

The GAWR is the Gross Axle Weight Rating. That is the maximum weight that can be carried on that axle. In your case 8000 lbs on the front Axle and 15000 lbs on the rear axle. The two combine or 23000 lbs should be your GVWR or Gross Vehicle Weight rating.

When you are running at max weight the recommended tire pressure is95 PSI front and rear.

The second image from Goodyear is the maximum tire load limit at certain tire pressures. I believe the chart you need to find is the one for recommended tire pressure at certain loads. From what I can see you are on the right track just trying to use the wrong Goodyear chart to determine the correct tire pressure.

With that said, have you driven your coach across a scale to get actual axle weights or are you looking for a rough starting point?

Attachments, after you select the attachment to include and you return to the edit window, click the arrow to the right of the attachment icon and then select the attachment to include at the cursors location. That is how to include the picture in the frame rather than as an attachment.
