It's not easy to control the vehicles during winter time, especailly in places where always snow in winter. In order to be more safe, many people put tyre studs into their tyres, this will give the tyre more force to grab the road, so it's more easy to drive and more safe for drivers and passengers. and coz of the high hardness of tungsten carbide material, we use carbide pins as the studs core. this will enlarge the lfe time of the tyre.
