Cinema's Williams Tyre was designed with Nathan Williams to be the perfect blend of speed and grip. It features a smooth continuous centreline tread that rolls super-fast and super grippy thanks to the micro-knurling across the side treads. The 2.5" width adds stability and softens hard landings, while still fitting in most modern frames.
