Cooper-your first tire looks good. You probably don't need my advice but I will offer a bit of what I learned in this process. I see a little air and this will be a small problem but I noticed one of your vent holes may not be on the highest point of the tire but I could not see all of them. That could be some cause for air. Also I think you will have a better chance of getting the air out if you keep the mold level in both directions when you are close to being full. Another thing I found was to not fill the vent holes. Just let the rubber barely get into the vent holes and the air still has a chance to escape. Also, if you have the working time, stop for a few minutes when it is about 90% full and let the air escape. Then finish filling it up. One other thing I found that saved a lot of time was to leave the mold open and pour the bottom half almost full then attach the top mold and finish filling.This will take a little practice but I'm sure you will get it right.
