Thanks for the info everyone. I was looking hard at the sale going on at carolinasrc which is why I wanted to know more about the tires.
The m3s I have for crimefighters are like mush, so I was concerned that a soft grp would be like that.
If they are more like an m2, then that is great. I'll look into ordering some jollys and atomics.
Was thinking of picking up a grip tire too, but maybe my steppin will cover the same range of use.
