If you really want to fine tune the air pressure you need the tire
load/inflation chart and you need to weight the axles with the van loaded as
it would be for normal travel. Then also consider that you need some reserve
since on a given axle the weight will not be evenly distributed across both
sides. VW often recommends the front tires have lower inflation than the
rears to induce some "under steer". As a Vanagon is loaded the rear axle
loads up very quick, especially the campers.

Here's a mathematical way to get correct pressure with new tires.
