It’s not just the tyres but the fact it’s a mountain bike, where you don’t choose your line as precariously as you would on a very stiff gravel bike as well as using your entire body as a shock absorbent instead of the MTB where you let the suspension and bigger tyres take the hit.
The old wisdom that buzz/vibration = fast comes to play here too.
Yeah but even on the road, where line choice is less important :) then my perception is that the 3" tyres seem faster. Can't be though. Or can they...?
