I'm curious is it possible to make a tyre that will fit perfectly on snowy/icy road. So I found studded tyres. Now, my question is - Is it possible to make studded tyre that will have good grip on snowy/icy road/sidewalk and use same tyre for dry road/sidewalk? Reason I want tyre with those specs is because I ride a bike in winter from house to work. Because it's too cold outside, I can't hold with traffic so I ride on sidewalk. Some sidewalks are clear, but on certain parts are ice or "compressed" snow. Without studded tyre it's not possible to brake or change direction. Where I should put screws in tyre? In middle or at sides of tyre?
