You want the Michelli Terrastrada Classico.
Anything else makes you a cheap fuck or simply illustrates your lack of style. That's important, because you need to be stylish when you're stuck in the mud.
It should be noted, however, that they only fit on factory wheels, and are only round when you are wearing Berluti loafers with ankle socks by Armani.
I think I read that somewhere here... Dan would know.
