Tyres are crucially important to the performance of your bike. A front tyre provides grip when cornering while also offering enough directional stability to keep the tyre tracking in a straight line. Even in the dry a full knobbly with a deep set of side knobs is less likely to wash out in turns once you start pushing it. In the wet a dedicated mud tyre can make all the difference. The open tread pattern will punch through the gloop and shed mud, helping you to find grip .
