I just installed four Michelans after using Yokohamas for about 25,000
miles on my 89 Westy with 165,000 miles. It's a restored vehicle with many
new major parts. The Yoko's were pretty much fried after 25,000 miles.

Their ride was good and I can't complain about traction except in snow
where they were not good. The Michelans are clearly better but more
expensive. They give a better ride and seem to track better. What I mean
is, (and I didn't realize this was a problem with the Yoko's), they don't
wander at highway speed. I hadn't realized the Yoko's did this until I
switched to another brand. It's a subtle effect. You might not even notice.

I'd give the Yoko's a "B" and, so far, the Michelans an "A."  I'm betting
they wil give me more miles.
