Consider Comfort When Inflating Road Tires - Don't always inflate road tires to the maximum pressure written on the tire label. Roads in the real world aren't billiard-table smooth. The jarring effect of bumpy pavement on over-inflated tires robs energy and makes for a bone-rattling ride. Judiciously inflated tires will roll over bumpy roads smoother and faster and get you home without shaking loose your dental work. You can go with higher pressures on ultra-smooth roads and when maximum speed is needed, such as in a time-trial or triathlon. But, stay at the lower end of the pressure zone for comfort on average to rough roads.
