I don't see that being that bad. It's no rail trail crushed but still medium/random sized gravel 30-40% coverage spread over a fine hard base that looks relatively compact. No potholes, washout, relatively consistent and no rollercoaster bumps. Worse would be several inches of fresh loose gravel or if the whole thing was medium/large pieces of various random depth. My last three gravel tires were Speedride 42, Hutchinson Overide 40 and Riddler 45. Maybe I'm wrong but I've ridden all kinds of gravel and surfaces and would use any of the three here depending on if there was a asphalt involved. I'm sure there would be some pings and shooting rocks from the tires. It's gravel, not asphalt so adjust accordingly.
