0 N.O.S. Posted February 7, 2010 Share Posted February 7, 2010 (edited) Isn't that the old designation for 7.50 x 20s? As fitted to GMC for example. Modern designation is width x rim diameter 34 x 7 defines a 7" high tyre, with overall diameter 34". So take off two heights of tyre (i.e. 14") from 34" gives the rim diameter of 20". A conventional tyre 7.5" wide would have a height of 7" (approx. 90% Aspect ratio?). Aspect ratio is height / width. Example of current conventional profile tyre 8.25 x 16 + 8.25" wide, standard aspect ratio (I think 90%?), on 16" rim Example of current low profile tyre 235/65 x 18 = 235mm wide, height = 65% of width, 18" rim.
