I need to purchase some tires today (my front one exploded yesterday afternoon, luckily it was in front of Sbucks rather than me on it attempting to ride with bag of grocery and 3 cups of coffee as was my plan...)and was thinking about this very thing. Do I go with standard , run of the mill type tires or should I drop a little more cash for an upgrade? Seeing as it's my everyday ride I probably won't go for anything too crazy but what performance advantages would there be?
