To the op, we have used and had good success with all. We are using the am 4" performance wheels right now with blue tread from mcmaster. It is a little gripper than am or IFI tread but only comes in wide sizes so it has to be cut (I think 3" is the narrowest)

While this is true, I have heard that the 2 in thick wheels wear better.
