The easiest way to keep your bicycle running well is regularly checking tire pressure. Properly inflated rubber rides best, lasts longest and resists flats. For high-pressure skinny road tires, check before every ride. For fatter rubber, such as what's on most off-road bikes, once a week is about right.
