The relatively new wide base tire has a number of distinct advantages: over duals. One of these, improved ride, is discussed. Data taken under static conditions shows the spring rate for the wide base tire to be substantially less than for duals under fully loaded conditions, with less difference appearing under lightly loaded conditions. This, it is believed, partly explains the tire behavior as it relates to impact absorption and bounce under dynamic loaded conditions, wherein an exaggerated bump condition is introduced. Over rough concrete, also, the data shows greater impact absorption for the wide base tires than for duals.
