I always used the Tioga Farmer John's Nephew in the 1990s and have been unable to source any since. These days i use something very different on both electric and pedal bikes - Schwalbe Fat Frank.
The 1990s Dart and Smoke Lite. The Dart wasn't much better than a normal Smoke but the Smoke Lite gave much better traction in mud than a normal Smoke - it was thin enough to dig in and find grip. I could ride up the golf course from the Plympton bike path (sorry golfers!) where I used to have to walk with a 2.1" Smoke on the back.
