I've been riding "Cannondale Synapse Carbon 6" all this while and its been a good exp till date but now as I am moving to a new place I'll be riding on Unpaved roads & some rough surfaces all the way to office. So I wanted to know what are the chances of the tires of my Cannondale being ripped! I've just spent few bucks in replacing them and I cannot afford to do it quite often. Any help would be appreciated !
