I'm running Shinko 705s. I'm on my 2nd set front, third set rear. They'd have lasted longer but I once forgot to fully inflate my tires after extensive off-road riding and rode home 500 miles on under-inflated tires. Really killed that set.
They are pretty good for off-road and yet not too buzzy on road.
I can see where those tires (80/20) would make that section even more challenging
