These Michelin XZL900s look bad to the bone, and nearly unobtainable.  Just think of it: a tire that's 36.5" X 10" X 16R (255/100R16) on your cruiser or crawler.  If I had my choice, I'd run these on 16" foreign market 80 series stock/factory steelies.  Fantasyland is great, isn't it?

34" X 10.5" X 15R  Interco LTBs are not a bad, but smaller substitute.
