New racing tires often contain volatile oils and compounds that can negatively affect grip and consistency. Heat cycling essentially pre-cures the tire, stabilizing the rubber compound and reducing the likelihood of abrupt performance drop-off during a race.
The process involves mounting the tires, bringing them up to a specific temperature range (usually through a few laps on the track or using tire warmers), and then allowing them to cool slowly and completely. This process is generally repeated 1-3 times. The history of heat cycling is intertwined with the evolution of racing tire technology, becoming crucial as tire compounds became more sophisticated.
Proper heat cycling can significantly improve a tire's grip, reduce wear, and make its performance more predictable over the course of a race or track session.
