There is no need to put on studs just because it snowed. Studs help on ice. If getting snow means getting ice then put on studs. The bottom line is studs help if you are going to be riding on ice. I have my studs on my bike now because we will have ice and/or icy patches here and there along roads for the next several months without fail. No ice? No studs needed. Good mtn bike tires with open lugs will work just fine for snow. Studs are of no real help for snow, but wow...they are a huge help on icy roads.
