Get a load chart from the tire manufacturer; it will give you the amount of air pressure required to support any load within the load range of the tire.

Weigh the vehicle, one axle at a time.

Divide the axle weight by 2, find that load on the chart and find the corresponding air pressure required to support that amount of weight.

Or call the tire manufacturer and give them the GVWR for each axle; they will be able to tell you the minimum amount of pressure required in that particular tire model to support the vehicle at its GVWR. That is how the vehicle manufacturer would have determined the inflation numbers in the door jamb.

Good luck,

That is my origianal question. I will ask again.

What is the best pressure for this tire installed on a Vanagon GL, given
the specifics of the tire itself?

Obviously it can handle a whopping load, and the very stiff sidewalls
make the van handle like it is on rails. No wandering in a wind or from
truck turbulance.

I was always taught to run the pressure that allows the tire to wear
evenly across the thread, what ever that pressure may be.

But in this case, how does one know??
