Conti Race King Protection as a 60/40 Road/Off-Road “Monster” tire?

I did notice that some of the knobs tore off in rough conditions, so I hope that doesn't turn into a problem. No leak, but a few of the knobs along the edge are GONE 

Knobs on the Raceking will tear off, but in my opinion, if you are riding something that rough, you need a different tire.  I've learned the advantages and limitations of the Raceking as I've been riding them in Western desert conditions for nearly five years.  They are great for most everything I  see and the float in sand that I get from a 2.2 tire prevents hike-a-bike for me.  I actually ground down the center knobs on my to make it smooth rolling on the road and now it does not give up much (other than an obviously greater weight) to road tires.  

Overall, if you want hard and fast, these aren't for you. But if you like comfort and traction when going gets rough, theses are the tire
I tested these once on a climb and I found very little difference between this and a GP4000, like less than 3 seconds for a five minute test at the same wattage.  You are not losing any speed compared to gravel tires and very little to road tires unless you are on super smooth roads running your road tires at 100psi.
