Yahoo Sports breaks down the two main forms of tyre degradation in Formula 1: graining and blistering. These conditions, while both detrimental to performance, stem from fundamentally different physical processes on the track.
Graining occurs when the tyre surface is abraded at low temperatures, causing rubber particles to form a slippery film over the tread. This typically happens on cold track surfaces or early in a stint, robbing the car of grip and increasing lap times. Blistering, in contrast, is a heat-related phenomenon where excessive surface temperatures cause the rubber to soften and form gas bubbles, which then burst and create pits.
The impacts on strategy are profound. Teams monitor tyre temperatures via sensors and simulations, adjusting pressures and camber to keep the rubber in the optimal window. Drivers also adapt their lines and braking inputs to manage degradation, especially on circuits like Barcelona or Silverstone known for high thermal loads.
Some experts argue that the emphasis on managing these tyre issues has reduced racing spectacle, as drivers must conserve rubber rather than push flat-out. The article notes that while graining can be cured with a few clean laps, blistering often signals terminal damage and forces an unscheduled pit stop.
