Do narrow tires puncture more frequently? Does a narrow bicycle tire puncture more often, or does it requires more attention regarding its maintenance and servicing?
Thin tires do get punctured more easily.  They also require that you fill them up more often, as they have a smaller volume of air, and at a much higher pressure, and therefore more quickly drop to a non-optimal pressure. Also, narrow tires will not be able to absorb as much impact as a wider mountain bike style tire, and therefore potholes and other obstacles will be more likely to warp the wheel.  However, if you have good tires, along with good quality wheels, and only ride on the roads, narrow tires can be extremely maintenance free both in terms of flats, and having your wheels stay true.  Just don't try to take them off any big jumps and watch out for potholes. Also, having a good quality floor/track pump can make filling the tires regularly less of a chore. As long as you're riding the tires in their designed environment (don't take road tires off-road), then maintenance and flats are more a factor due to tire and wheel quality than to the width of the tire.
