I could write for ever about tires, The mold release is a waxy product that stood up to the heat of hot rubber in the mold you could scrub for ever and not remove it, notice on the floor that he didn't really remove much tire surface at all, it would take you a few races to achieve this result, speed is the name of this game a thinner tire heats and cools quicker, I have lath cut tires that last 1 race in the name of speed, washing the tires after every race is vital just like a mud mask removes oils from a face the mud can suck your tires dry of the oils that make up the rubber and cause them to harden up and cause less grip.
