I'll have to think about this a bit, but at first light, it seems 
reasonable, because .50/.80 = .625 and .50/.82 = .610, so this pretty 
much brackets the ratio of km to miles.

(our mi/hr speedos came in both .80 and .82 versions, perhaps 
more....)  

I've almost forgotten what this all boiled down to. Was it that .82 
meant 820 tire revolutions to the mile? In that case, 500 tire 
revolutions to the km would be exactly right.

Interesting that these tires would come to such an even number of 
revolutions per km. (Perhaps just one more justification for the 
metric system.  ;-)

Thanks for catching this!
