Best Tire/Wheel for CRT Truggy?

I'm new to 1/8. Building a CRT conversion as I type. Looking for suggestions on what tires work best for all around bashing. My track has a combo of loose and packed dirt. But before I choose a tire I must first select the rim. I was thinking about the 40 series pro-line rims.

Would this require me to get 23 mm adapters? My hubs currently measure 17mm. Do they make these for CRT's (Excuse the ignorance on my part).
Offset considerations?


All input appreciated.....
