     I don't think 205's are wide enough. On my '73 westy I had 235/75/15 for
awhile, then put in a tranny with a bit higher final drive and had to drop to
215/75/15. And that's what I'd prefer to run on my '82 diesel westy but after
trying it a bit it seems obvious that the power just isn't there for that tall a
tire. When I get a nice 1.9TD in it I'll put them back on, but for now I'll have
to live with little 205/70/15.

    Think digging those narrow little tires into some mud or loose sand and
you'll be cursing them when you spend two days of your vacation digging and
jacking your way out of some wayback hole on the way to a good fishing spot.
4wd doesn't help a whole lot if you start sinking.
