Actually, the stock tires on post-1963 Busses and Vanagons are the same size
- 185R14. The only exception is Vanagons with the optional factory alloy
wheels, which were originally equippped with 205/70R14. However, I run the
185R14's on my Vanagon even though it has alloy wheels. They are still
within specs for the alloy wheel, and as George pointed out, have an
advantage over a wider tire in terms of snow traction (as well as a reduced
tendancy to hydroplane). Additionally, there is better selection and
availability of reinforced tires in this size, and they tend to be much
cheaper.
