Back to work,,, top half of tire mold poured. Have to wait till tomorrow to take apart and cut casting holes and cast first tire. Have an idea of how much black pigment to add from making the haul truck tires. But not exact. Hopefully I nail it on first one cuz material ain’t cheep. And I’m casting them a solid tire shore hardness of 40, same as haul truck tires. Too much work to make them hollow verses cost savings.
