I run Conti. Explorers and Michelin Pro 3’s on mountain and road bikes respectively. Never have, and never will, constantly swap for varying conditions – they stay on till they’re bald!
Their is so much boolaks talked about tyre choice – particularly on this forum.
However, for cx racing, I have 3 sets of different tyres for various conditions, which I constantly change around.
This is because I am so krapp, I need a multitude of excuses why I finish so far down the field, and wrong tyre choice feels quite convincing. 🙂
