Before you throw yourself into the bottomless pit of Vanagon tire
selection, I suggest you look at

and use the tire and gearing calculators at

www.4lo.com

to assess the end result of your changes prior to spending money.  In
the Vanagon world, it is very common to use a non-stock tire size as a
less expensive alternative to gearing changes.  The stock diesel engine
does not have enough power to turn large and heavy tires.  Small gearing
changes make a large difference in driveability.  Due to the low-powered
engine and aerodynamic drag, even the largest gearing changes don't have
a large effect on maximum cruising speed.

The vast majority of North American diesel Vanagons have DZ
transmissions.  They all came with 185R14 tires, which have an aspect
ratio of 82 (185/82R14).  The DM 4 speed transmission works superbly
with the stock tires, even on a loaded camper.  No tire that will fit on
the Vanagon can make up the difference in gearing between these two
transmissions.  Being satisfied with a diesel Vanagon is all about
learning to enjoy the "slow road".  If you can't live with that, there
are several options for larger engines and turbocharging.
