I have Veeco Speedsters smooth threads on my fat tire bike. Dang, they were $70 each. They do roll well, and I can pedal my fat tire bike w/o power, one of the reasons I wanted a front derailleur. When the bike was unpowered, with steel rims and heavy rubber tires, I couldn't pedal it 2 miles. I saved about 3 pounds per wheel just by going to lighter tires/tubes and alloy rims. Rolling resistance and angular momentum affect pedalling.
However, I prefer to ride skinny tires om a bike that weighs half the weight.
