I'm thinking seriously I need to pull my bike off the hooks in the garage and do a bit of biking come spring time. It's an early or mid-90s Schwinn Impact mountain bike so it's OK but nothing real high end. Currently it has pretty knobby tires on it and I'm thinking 97% of any future use will be paved roads and or hard bike trails so looking at a city / hybrid type of tire. So, looking for opinions from a cyclist if there is real benefit (lower rolling resistance, etc.) to a "premium" bicycle tire maybe like a Michelin City or just grab something local that has more of a street tread? I'm not to worried about cost difference, but no sense doing it if there isn't really any benefit.
