Higher aspect ratio is taller. 245/65R17 is what he put on. 245 mm width 245 * 0.65 = 159.25 mm height 17 * 25.4 + 2(159.25) = 750.3 mm overall diameter (29.54") Everything I read I read says either 255/60R17 255 mm width 255 * 0.60 = 153 mm height 17 * 25.4 + 2(153) = 737.8 mm overall diameter (29.047") or 275/55R17. 275 mm width 275 * 0.55 = 151.25 mm height 17 * 25.4 + 2(151.25) = 734.3 mm overall diameter (28.91") One could use the above information to figure speedometer error, but it would be best to go to manufacturers' websites to find the "revs per mile" for each tire.
