It would be interesting to hear from a tire engineer on what change over temperature you need to achieve to officially put a heat cycle on a tire.

It isn't uncommon for me to see surface temps of around ~130F on the tire (~54C). And I'm just using an IR gun...the internal temperatures if taken with a pyrometer I bet they will be even higher.


Make sure you get the mold release and scrub the tire in. It seems like you've done that already since your drive...but I would suspect just given the fresh tread that the one tire may take a bit longer to get to temp
