Speed Symbol - A symbol indicating the maximum speed at which the tyre can carry a load corresponding to its Load Index under specific service conditions.
Speed category - "ZR" a category assigned to a tyre which denotes the speed capability for which a tyre is rated.
N.B. where the tyre size designation includes the letters "ZR" followed by a Service Description then the speed rating is that indicated by Service Description, e.g. 235/45ZR17 94W.
