Here are some photos of the wheels on a scale. We use this scale for shipping so it should be pretty accurate...
By the way, I checked the runout... a respectable 11 thousandths over about a quarter turn.
Tires should be mounted today. I'll weigh them again afterward.
The wheels do not come with valve stems but it appears to accept a typical rubber valve, though I'm going to see if any of the metal valves I have here will work.
