Mark,

It seems to be the consensus that Michelins are THE tire to buy.
I purchased an immaculate 89 Westy last fall that came with
US made 27x8.5 load range D off road truck tires.  It is also
consensus that they're not supposed to work on a Vanagon.
I was a long time loaf owner and the van does ride much rougher.

Howver, I'm not convinced it's because of the tires. When I posted
a question regarding similarities and differences between vans and
loafs, one listee noted the vanagon has a less "compliant" rear
suspension. I believe the idea has merit.

I have enjoyed having greater ground clearance with the big
meats. A listee also mentioned that 27x8.5's are the tallest 14 in
tire made.  IMHO they handle well in town, on the highway,
and especially off-road.  Since off-road camping is a major
reason I own a Westy, I will replace them when needed with
the same size.

BTW, I was a type2 listee for some time before my bus was crashed.
People on that list swear by Yokohamas.

ALWAYS keep to the high road (the scenery is much nicer)
