Common list theory now seems to be about the same for all Vanagon
factory info. VW employs a number of automotive engineers and
professional test drivers. In conjunction with some instrumentation,
various test tracks and roads, and in consultation with the tire
manufacturers, these VW fools come up with some off-the-wall numbers and
the company puts them in the manuals and door stickers to endanger all
our lives and shorten the service life of the vehicles.

My personal theory is that they know what they are doing and are usually
right.
