Actually, a 185R14 is suitable for a 5.0-6.0 rim width.  The stock steel
Vanagon wheel is 5.5, the alloy 6.0, so a 185R14 is equally appropriate for
either wheel. But a 185R14 has some advantages over a wider tire. A wider
tire will generally provide better dry-weather traction (all things being
equal), but on the flip side it is more prone to hydroplaning than a
narrower tire and can have worse traction in snow.  To me, these negatives
offset the positive. A 185R14 will tend to do better in poor-weather driving
conditons, which is when I am most worried about safe handling. Dry weather
handling is predictable, and you can easlily learn your vehicle's (and
tire's) limits. Poor weather handling is less predictable. I fully trust my
Vanagon on dry roads. It's when I'm gripping the steering wheel driving down
a dark highway during a pounding rain (or snow) that I really need to count
on my tires to grip the road. This is where a narrower tire excels, and
that's why I use 185R14's on my own Vanagon with alloys. A side benefit is
the cost savings; a 185R14 is generally significantly cheaper than a
comparable 205-70R14.
