Default Correct Speedometer Gear P255 R60 15 3.08 Differential Gear Ratio

I have been trying to cross reference factory tire heights with the P255 R60 15 tire height, and 3.08 gear ratio.

The 43 tooth appears to be a close match.

3.08 1362196 43 PURPLE F78 x 14 ( 26.5 to 27 inch height) Drive gear teeth = 18

Could somebody with the same tire size and rear gearing please confirm?
