I totally agree . When I skated San Francisco , I was skating a 8.5" board , but 55mm wheels . Boston's wondeful brick everything , IIRC probably 53mm , the lowest I go . When I skate Street I do a lot of wallrides , bean-plants , etc...and need some " meat " underneath my bigger board . I don't ride anything bigger than 63mm , and that's usually skating vert / bowls .
