Using the formula: -------- NewGearRatio = (NewTireDia / OldTireDia) X OldGearRatio ------,
We can find the effect of different gear ratios and tire sizes and how they compare performance-wise with the stock ratio and stock size tires.
37 / 31.5 x 3.73 = 4.38. So 4.30's will get the effective ratio back to the stock 3.73 ratio.
For a 4.10 effective ratio, just plug in 4.10 for 3.73 in the same equation: 37 / 31.5 x 4.10 = 4.82. So 4.88's would be similar to a 4.10 ratio with stock tires.
If we plug in 3.90 for 3.73 in the equation: 37 / 31.5 x 3.90 = 4.58. So 4.56's would be similar to stock tires with a 3.90 ratio.
By the way, I run 4.56's with 33's on my gas-powered F350, for an approx 4.30 effective ratio .
