“Best” all around axle ratio: ~450hp w/ A904?

The tires don’t measure their nominal size and that makes the math wrong?

All it means is that someone didn’t do their due diligence before applying the math.

The math isn’t wrong. The assumption made was wrong.

No, you misunderstand me. But yes on the tires. (As one example) That is to say, if you believe what the manufacturer says what the diameter is. Which is not always true. The diameter varies (actual tire size) from manufacture to manufacture.

Math is math and if you didn’t make a mistake in the math, then your math will be right and the thing your working with should work.
