Schwalbe Big Apples, as big as you can fit*
With enough miles to wear out 3 cassettes on my big dummy, the Big Apples are still going strong. Back is just barely worn.
Tread doesn't do much unless it's real knobs. I ride the big apples on dirt and gravel and they work great.
*also, don't run tires twice or more the width of your rim, they get squirmy.
