See ya there!!!!! I'm doing it as well. Did it last year and it is NOT to be missed!!!
Couple things;
From where are you coming?
No, there is no where near to do a tire swap. Pahrump would be the closest and this would be limited.
Having done this ride and ridden the terrain they have laid out for us, I would recommend riding in on whatever you have on now and then swap there or somewhere near.
I offer up my place (Sacramento) for you to stop over. We can put rubber on there and ride down. Once done you can either ride home or back to my place to swap back.
I ran on Metzeler Karoo (not the T) and most everyone else was on TKCs.
Go to Jimmy Lewis' website and read his tire recommendation section.
Yes, the K60 will work but it will not allow you to fully enjoy the terrain and ride. There is a bunch of soft sections that really need a much more dedicated tire than the K60 provides.
Just my opinion, having been there and done that. Of course, many may chime in and offer alternatives but, IMO, you are going to want the best off road tire you can get for this terrain.
Regardless, if it works out, you can use my place as a stopover.
