   In this example, the 185 is the aspect ratio, the 60 is the tire 
width, and the H is a designation of the tire sidewall height...I
have a set of sport radials that are supposed to have a speed rating
of 180 *mph* (they are Swedish tires too) and there is no other
leter before the R that means radial...
