As for tires and speedo calibration, approx 23.5" OD is what the 120mph speedo and pcm are calibrated for, so here's a list of tires that will make a negligible difference to the speedo:

185/65-14 (35-50mm offset wheels needed)
195/60-14 (35-45mm offset wheels needed)
205/60-14 (38-43mm offset wheels needed)
185/60-15 (35-50mm offset wheels needed)
195/55-15 (35-45mm offset wheels needed)
205/55-15 (40-43mm offset wheels needed)
215/50-15 (42-43mm offset wheels needed)
195/50-16 (35-45mm offset wheels needed)
205/45-16 (40-43mm offset wheels needed)
215/45-16 (42-43mm offset wheels needed)
205/40-17 (40-43mm offset wheels needed)
215/40-17 (42-43mm offset wheels needed)
