23mm hex E-revo wheels and tires, suggestions?

[simplechamp]

I want to get a new set of tires and wheels for my E-revo. The tires that came on it are the Proline MT Crimefighters. The wheels are a plain black disk with 23mm hexes, not sure what brand.

I want a spare set of wheels/tires tailored more towards bashing. Something with more of a realistic monster truck lug pattern as opposed to the pin-type tires I have. I want to get the same wheels, so can anyone suggest what they may be? Or a similar plain black disk wheel with 23mm hexes?

EDIT: The wheels I have right now are right around 3.5" in diameter, if that helps. Also, what does "40 series" wheels mean?
