The thing about studded tires is that you are riding on metal studs, whether they have ice to grip or not. They work best on smooth flat porous ice of some thickness, but epsecially if you have a decent tire pressure up to minimize the "tractor with a flat tire" feeling, carbide studs and cold rubber will never give you the same grip that dry warm rubber will. You can give it your all when going straight ahead, but think of skating, be careful of cornering or banking, and try lower pressure first until you know your tires well. I had a most spectacular slide-out when braking with studs on a smooth granite pavement - I left stripes several meters long
