Rear hub vs mid drive

I took the mid drive (Frey CC) and hub (Espin Sport) out for back to back spins today. I rode the Sport about 15 miles (95% street and sidewalk) and the CC about 10 miles. (50-50 dirt trails/street)
I think I need different tires for my CC as the Schwalbes did not feel super stable in sandy conditions. The Sport just keeps on keepin on and offers a great comfort ride. I of course have added the suspension seat post and suspension stem, but for 1200 bucks vs the 4k I spent on the CC, the value is with Espin...
What model and size tires are on the Frey CC? You mention Schwalbe, but they have so many model tires....
 
Geez, I love those tires! Low rolling resistance, great ride, and for what sand I've encountered with them so far (nothing deep, but plenty loose) they've behaved pretty well. Running 35psi front and 40 rear - but I'm 300lbs too....

I may take some air out. I have them at 45
