In normal operation, they do not extend beyond the tread, which remains very smooth because they are housed in a small cavity. This allows you to both gain traction when you need it and maintain speed.Nano HubsNano hubs are multi-faceted cats whose angles, shape and size vary at the periphery of the rolling strip. They provide better grip on various road surfaces thanks to their fine and flexible grain.UTC rubberTioga UTC rubber contains special additives to improve traction and grip without compromising rolling efficiency.
