Tyres are vital. You can become obsessed with finding the right tyre. Whether you're a road cyclist or a mountain biker or just an every day commuter, we all appreciate a good tyre. We end up having favourite tyres and preferred brands. Sometimes we don't venture too far beyond what we know. Still to this day the most common tyre that people buy is a direct and exact replacement of the tyre that their bike came supplied with. You can't have too many tyres. The sign of a true cyclist is someone who has a pile of tyres tangled up in their garage, shed or bike room.
