Yes, open pros... And I suspect the Clement to be on the large side of 35c... It doesn't look silly though, pretty much every MTB in the 90s looked like that (ratio rim / tire widths)
Make sense, they're fine until you go beyond 28mm, which result in needing to pump the tyres a bit more to stop from feeling overly squirmy in corner, which take away the advantage of a larger tyres.
Were you running narrow rims with those tyres?
