🏆 Race Case Study

2021 Russian GP — Norris's Late Switch to Intermediates

Late in the 2021 Russian Grand Prix, rain began to fall while Lando Norris was leading the race. Norris initially chose to remain on slick tires, but as the rain intensified, the track became too wet to maintain sufficient grip. Drivers who switched earlier to intermediate tires gained a significant advantage in the changing conditions. Norris eventually made the switch, but only after losing substantial time, making the race a memorable example of how crucial tire timing can be in mixed conditions.

Frequently asked questions

When are intermediate tires used in F1?
Intermediate tires are used when the track is wet but does not have enough standing water to require full wet tires. They provide more grip than slicks in damp or moderately wet conditions while remaining suitable for a drying track.
What is the difference between intermediate and full wet tires?
Intermediate tires are designed for damp to moderately wet conditions and use grooves to clear smaller amounts of water. Full wet tires have a more aggressive tread pattern for clearing larger amounts of water and reducing the risk of aquaplaning in heavy rain.
