I suppose as long as the bike is predictable I could adjust to it. If
the tire combination makes the handling squirrely I'd be looking to
swap them out pretty quick.

Interesting description. That is what the Venture felt like when I
switched to the narrower tire.

Interesting stuff. Thanks for posting.
