yokohama might have something , tho I think any 650's and maybe even 750's will prolly be trailer tires so not likely traction tread - the closest I found for my 46 was 850x20 [bias ply] - fronts rubbed slightly on hard turns, but the back were fine w/ proper pressure - wouldn't try puttin 19.5's on
I've got 700x15LTR Yokohama tractions on the back of the red58 now, and they're excellent tires w/ a good truck height, narrow tread
