Aftter 16 more hrs. of cure time I separated the mold halves and this is how it looked-
This is the molds ready for pouring the tires-
I sprayed release wax on the molds and poured the black rubber mixture in the molds. To speed up this process I filled the bottom half about 2/3 full before closing the molds-
I had the molds on a perfectly level table to pour in the remaining rubber. I feel this is an important step to be sure the mold is full and to release all air. If air gets trapped in the mold the tire will be flawed.
