Tire Selection and Allocation
Teams carefully decide when and how to use each tire compound, a choice that can significantly influence the outcome of a race weekend.
Tire Compound Basics
Pirelli provides three main tire compounds for every Grand Prix weekend: soft, medium, and hard. Each compound is designed to strike a balance between grip and durability, with softer tires offering better short-term performance and harder tires prioritizing endurance.
- Soft tires deliver maximum grip, making them ideal for short runs like qualifying laps or sprint races. However, they wear out quickly, which limits their use in long stints.
- Medium tires offer a compromise between performance and durability. These versatile tires are often central to race strategies, providing solid lap times while lasting longer than soft compounds.
- Hard tires are built for endurance. While not as fast as their softer counterparts, they maintain consistent performance over extended stints, making them useful for long-distance strategies.
Soft tires heat up quickly but are prone to overheating, while hard tires take longer to warm up but perform reliably across a range of conditions. These differences in characteristics directly influence how teams approach their tire usage within the rules set by the FIA.
FIA Tire Allocation Rules
The FIA regulates how teams use their limited tire sets over the course of a race weekend. For a standard Grand Prix, each car is allocated 13 sets of dry-weather tires, with additional wet-weather tires provided if necessary.
To ensure fairness, the FIA requires teams to return specific tire sets during practice sessions. For example, two sets must be returned after the first practice session, and another set after the second session. This prevents teams from stockpiling tires for later use.
A key rule during qualifying is that cars advancing to Q2 must start the race on the same tire compound they used for their fastest Q2 lap. This adds a layer of strategy, as teams must weigh the benefits of qualifying speed against the potential impact on race-day performance.
By the time the race begins, teams typically have 8-9 fresh sets of tires remaining, depending on how they managed their allocation during practice and qualifying. Teams rely on historical data and track-specific analysis to decide how to distribute their tire usage throughout the weekend, taking into account factors like track layout and weather conditions.
To conserve fresh tires, teams often use worn sets during practice sessions for installation laps and setup adjustments. This approach allows them to gather crucial data while saving their best tires for qualifying and the race. Engineers, strategists, and drivers must work seamlessly to balance data collection with tire preservation.
Adjustments for Sprint Weekends and Weather
Sprint weekend formats, with their compressed schedules, bring unique challenges to tire allocation. With fewer practice sessions and different tire return rules, teams are forced to adapt their strategies. The same total allocation applies, but the altered session structure often leads to more aggressive tire use during the limited practice time available.
Unpredictable weather adds another layer of complexity. Teams must plan for both dry and wet conditions within their tire allocation, especially at circuits known for sudden weather changes. This often results in more conservative strategies to ensure they are prepared for any scenario.
Ultimately, tire allocation is more than just resource management - it’s a key component of race strategy. From planning pit stops to adapting to changing conditions, how teams handle their tires can make the difference between victory and defeat.
Pre-Race Tire Preparation Steps
Once teams finalize their tire allocation strategy, the focus shifts to meticulous preparation to ensure every tire is ready to perform at its best. This process is critical, as it can directly impact the success of pit stops and, ultimately, race results. Here’s a closer look at how teams prepare their tires for peak performance.
Heating Tires with Tire Blankets
Tire blankets are a cornerstone of any F1 garage. These electric covers are designed to keep tires at their ideal operating temperature before they ever touch the track. Without pre-heating, tires need additional laps to reach the right temperature, costing valuable time during the race.
Modern tire blankets come equipped with built-in heating elements that evenly distribute heat across the tire surface. Electronic controllers ensure precise temperature regulation, tailored to the specific requirements of each tire compound. Since different compounds perform best within specific temperature ranges, this precision allows drivers to hit the track with tires already primed for maximum grip and performance.
Setting and Checking Tire Pressure
Tire pressure is another critical factor that teams fine-tune based on the compound type and track conditions. The electronic systems in tire blankets not only manage temperature but also monitor air pressure. As tires heat up, the air inside expands, and these systems automatically adjust to maintain the correct pressure.
In addition to these automated controls, crew members regularly perform manual checks using precision gauges. This double-check ensures that pressures remain within the optimal range, providing the consistency and reliability drivers need during high-pressure moments on the track.
Tire Storage and Handling Methods
Once the tires are heated and pressure-checked, teams take great care to preserve their condition through careful storage and handling. Each mounted tire is kept in its electric cover and stored on dedicated carts for quick access. These carts are clearly labeled, allowing for rapid deployment during pit stops.
Before the race weekend even begins, Pirelli manages the mounting, balancing, and filling of all tires onto team-owned wheels in a dedicated fitting tent. This centralized process ensures that no team has unmounted tires, protecting Pirelli's proprietary technology. Throughout the weekend, Pirelli also tracks every tire using barcodes and scanners, ensuring compliance with regulations and maintaining accountability.
To minimize risks like contamination or delays, teams position tire carts strategically in the garage. These measures ensure the tires remain in perfect condition until they are needed. Such attention to detail plays a crucial role in executing fast, efficient pit stops, which can often decide the outcome of a race.
Pit Stop Tire Management and Crew Coordination
When a Formula 1 car enters the pit lane, it triggers a perfectly timed, high-speed operation. Every crew member knows their role, and the goal is simple: swap out the tires as fast and as safely as possible.
Pit Crew Member Responsibilities
Each member of the pit crew has a specific job, and they perform it with incredible accuracy. Some handle the wheel guns to remove and secure the nuts, others manage the tires themselves, and a few operate the jacks that lift and lower the car. Overseeing this entire process is the crew chief, who ensures everything runs smoothly by coordinating communication and making quick, decisive calls. This level of organization sets the stage for the advanced tools used during the stop.
Pit Stop Tools and Equipment
F1 teams depend on state-of-the-art tools to make tire changes lightning fast. Pneumatic wheel guns are built to remove and secure wheel nuts in seconds.

Advanced simulators and data analysis help refine each crew member's performance and identify areas for improvement. Streamlined communication and carefully planned tool placement eliminate even the smallest delays. In a sport where every fraction of a second matters, this level of precision can make or break a race.
Post-Pit Stop Tire Checks and Data Review
After a pit stop, teams dive straight into performance data to fine-tune their strategies for upcoming stops. This immediate feedback loop helps maintain the high standards demanded during a race.
Checking Tire Condition After Pit Stops
Once the car is back on track, the pit crew quickly assesses the condition of the replaced tires. They look for signs of wear, cuts, debris, or any damage to the sidewalls - issues that can hint at kerb impacts or even suspension problems.
Onboard sensors provide tire temperature data, which teams use to ensure the tires are performing as expected. This data also confirms that the correct tire compound was installed - an essential check when every fraction of a second matters during a pit stop.
Using Data to Improve Future Pit Stops
Telemetry analysis begins the moment the car enters the pit lane. Engineers review how the car decelerates, its positioning on pit entry, and the time it takes to reach the pit box. These details help refine the crew's timing and execution, aligning pit stop efficiency with the broader race strategy.
Wheel gun and jack response times are scrutinized to shave off milliseconds. High-speed video footage captures crew movements and tool handling, allowing teams to tweak routines for peak efficiency.
