That list was good in its day but you'll be hard pressed to find most of the covers it lists in 27" nowadays. Still available are Schwalbe Marathon and Road Cruiser, Michelin Protek, Continental Ride Tour and Super Sport, Panaracer Pasela, all 32-630 And of course various no-name tyres - do you really want to go lower than Schwalbe Road Cruiser?
Any others?
