Lots of factors to determine tire size and type. But typically, a slick will be fastest for road/smooth hardpack. If you need some tread, then Continental Terra Speed or Schwalbe G-One Allround are the fastest knobbed tires.
I have the G ones now , I find them a bit slow on pavement which I ride 60% of the time . Maybe its me ,I have nothing to compare them to . Its time for new tires so I want to make sure I get the right ones. Thanks
