After an overnight cure I separated the molds and this is the first tire right out of the mold-

Another-

I have these stems on the side of the tire from the pour holes and air vents but I can grind these off and turn this to the inside and I don't think it will be a problem.

Using this process I don't see any way to avoid this and I have a few tiny air bubbles on the fill side but I believe I can rig a shaker on the table and possibly solve this. I am happy with the results but will try to improve on the remaining tires. If anyone has any questions I will be glad to answer them.
