What Gears???

I think it is an extremely personal thing like anything else. IMO, you need facts. I gave mine above to what it approx. spins at on the Hwy. and by the way, that speed was below 65. I did fail to mention that.

A lot depends on the personal taste of what can be put up with and the intended usage and perimeters of the driving range or experience.
Also that tire size is completely unfamiliar to me. What's the inches in diameter?
