Yoyo, It's been a while since I did it; I've had zero issues since, so I am unable to tell you how much I put in, however the website told me. The filling is the fun part; I followed the instructions on the website, and modified to suit. I used a 'sauce ' bottle; I guess you guys would call it a ketchup bottle; a bottle with a tapered nozzle...I filled the bottle with the required amount of beads. Used a bit of clear plastic tubing of appropriate size to fit over the threaded portion of the valve stem and onto the spout of the sauce bottle. Idea is, remove the valve from the stem, fit the plastic tube onto v/v stem, pour some beads down the tube [you can see them because the plastic tubing is clear], until they've backed up about an inch into the tube, remove bottle, insert a compressed air duster gun over tube and blow the beads into the tire. Repeat until all beads are installed.
Now, I had trouble doing this initially, the beads would back up and refuse to blow into the tube. I figured there's like a flap of rubber at the base of the valve stem that was plugging up the works...I used a drill bit in a drill through the valve stem to clear this obstruction. Worked better after that. Don't drill through the opposite side of the tube!! All in all, the entire operation to fill 5 tubes took around 2 hours.
sorry I can't be more concise!
