Those tires look awesome! Great modeling on them, much better than a boolean.

As far as the rims go, what are the choices between? These rims you have now look pretty good, but when compared to the effort put forth into the tire, they seem kinda plain. The spoke look is definitely cool, but I'd add a bit of flare to them. I hate to use the word 'flare', but I couldn't think of anything else:p
