I have the 804/805 combo on my bike. About 3000 miles so far and judging by my rear tire I woulg guess I can get 6000 out of it. It was lumpy below 10mph as previously stated for the first few hundred miles but thats gone now. I had the bike in Colorado so I was ripping around mountain roads on the way to ride the mountain passes. Excellent traction on everything on and offroad- I’m planning on a second set when mine go.
