I fitted 185/70 Vredestein Sprint Classics to Bumble and they were excellent.
That size is close to the crosshead though, so beware if you chose them.
But it is the same size as the original Contis...
[Edit] I did not read your post with sufficient care! Anyway, it's the 165/80 I am going for - it is a tight fit for anything else under the 4/4's arches.
