You can't do it all in one trip. Hopefully you'll be back again sometime to fill in the gaps.
I'd recommend a set of Metzeler ME880s for your bike. They'll probably last the whole trip.
You may want to consider a bit of a loop into Southwestern Colorado between Monument Valley and Santa Fe. There is some mighty fine scenery and riding in that little corner of the USA.
You might want to break this 560 mile section into two days, overnighting in Pagosa Springs, Colorado. It's epic!
