…The fat tyres do produce a bit more drag…
I’d like to see a real world comparison on second class roads at touring speeds.
I’m convinced there is less drag with my 2.35″ Big Apples on roads where the surface is rough (eg exposed aggregate).
When freewheeling downhill (on those sort of surfaces) my bike runs ahead of other bikes I have ridden beside.
On dead smooth tarmac, it does fell a little more draggy, but there’s bugger-all of that around here.
Naturally the finely honed athletes of STW who ride everywhere at 31.5mph will need a more aerodynamic tyre, but for cruising speeds up to say 18mph, it feels to me like they roll at least as easily.
