17 or 18 inch wheels, Pro's or Con's either way

[tyoneal]

To All:

Is there any advantage of either one of these sizes over the other?

17 inch:

Less rotating mass, 13 inch maximum Rotor size, ???

18 inch:

More rotating mass, 14 inch maximum Rotor size, ???

What are you using and why? (Looks are a reason, but I am particularly interested in performance reasons)

Thanks again,

tyoneal
