F1 Teams Continue Spring Testing
Multiple Formula 1 teams remain scheduled for track activity throughout April as part of Pirelli's ongoing development testing programme. The tyre supplier's continued evaluation work keeps several squads engaged in competition preparation during the spring months.

Pirelli's Development Programme Extends Into April
The Formula 1 calendar may have moved beyond its opening rounds, but the action on track is far from finished for all participants. A selection of teams from the grid have confirmed their continued presence at racing facilities across April, with their involvement directly tied to Pirelli's comprehensive development testing schedule.
As the official tyre supplier for the sport, Pirelli maintains an extensive programme dedicated to advancing compound performance, understanding tyre behaviour across different track conditions, and gathering crucial data that informs future specification decisions. This testing initiative represents a significant ongoing commitment to innovation within Formula 1's technical landscape.
Teams Engaged in Spring Track Activity
The squads maintaining an April presence form part of Pirelli's broader testing framework, which extends beyond the conventional race weekend format. These teams play a vital role in the tyre manufacturer's research and development efforts, providing real-world feedback and performance metrics that shape the competitive equipment used throughout the season.
The involvement of multiple teams underscores the collaborative nature of F1's technical development. Rather than operating in isolation, Pirelli coordinates with various squads to gather diverse data across different car setups, driver preferences, and chassis configurations. This multi-team approach enables the tyre supplier to develop compounds that function effectively across the full spectrum of Formula 1 machinery.
The Importance of Continuous Testing
Testing programmes extending into April demonstrate the meticulous preparation that characterises modern Formula 1. The sport's relentless pursuit of performance optimization means that development work never truly ceases. Even as the season progresses, teams and suppliers continue refining their approaches, gathering intelligence, and preparing updated specifications for future events.
Pirelli's development testing carries particular significance given the demands placed on tyres in contemporary Formula 1. Compounds must deliver consistent performance across vastly different circuit characteristics—from high-speed, low-degradation layouts to tight, technical configurations demanding significant tyre management. The data gathered during spring testing sessions directly contributes to tyre selections and specifications for upcoming races.
Track Time Beyond Race Weekends
The presence of F1 teams at testing facilities during April serves multiple purposes beyond simple tyre evaluation. Drivers benefit from extended seat time in their vehicles, engineers gain valuable data points for setup refinement, and technical teams gather information relevant to their ongoing development programmes. For teams, these testing opportunities represent essential preparation time that complements their race weekend activities.
Pirelli's commitment to continuous development testing reflects the competitive nature of Formula 1, where marginal gains translate to meaningful performance advantages. The tyre supplier must remain responsive to evolving technical regulations, changing weather patterns across the season, and the constant innovations introduced by teams seeking competitive edge.
Looking Forward
The scheduled April testing underscores that Formula 1's technical ecosystem operates throughout the year, with multiple layers of development occurring simultaneously. While race weekends capture the sport's public attention, the behind-the-scenes work conducted during dedicated testing sessions proves equally essential to competitive success.
For the teams participating in Pirelli's April testing programme, these sessions represent valuable opportunities to contribute to tyre development while simultaneously advancing their own technical understanding. As the season unfolds, the insights gathered during these spring activities will prove instrumental in shaping performance across subsequent race weekends.
The continuation of testing activities into April demonstrates that Formula 1 remains a sport of constant evolution and refinement, where even the quieter months between races maintain significance for those committed to technological advancement.

Tyre Specifications
Chapter: Chapter IX - Tyres
In Simple Terms
Pirelli is F1's sole tyre supplier. Each driver gets a fixed allocation per weekend: typically 13 sets of slicks (across soft, medium, hard), plus wet weather tyres. Teams must strategically use their allocation across practice, qualifying, and the race.
- Pirelli is sole official supplier
- Fixed allocation per weekend
- Three dry compounds: soft, medium, hard
- Intermediate and wet also provided
Official FIA Text
Only tyres supplied by the official tyre supplier may be used. During a race weekend, each driver is allocated a specified number of dry weather tyre sets comprising soft, medium and hard compounds, plus intermediate and wet weather tyres.
Article B6.1.1
Supply Of Tyres
Chapter: B6
In Simple Terms
F1 has one official tyre supplier who must make three different types of dry-weather tyres, plus intermediate and wet-weather tyres available to all teams. Each tyre type looks visibly different so everyone knows which compound is being used. Sometimes extra experimental tyres are tested during races.
- Single tyre manufacturer provides all tyres for the season
- Three dry-weather tyre specifications must be available (soft, medium, hard compounds)
- One intermediate and one wet-weather tyre specification each
- All tyre types must be visibly distinguishable from one another
Official FIA Text
The single tyre manufacturer must provide three specifications of dry-weather tyre, one specification of intermediate tyre, and one specification of wet-weather tyre, each visibly distinguishable. Additional tyre specifications may be made available for In-Competition Tyre Evaluation and In-Competition Tyre Testing at certain Competitions.
Article B11.2.1
TCC General Conditions
Chapter: B
In Simple Terms
Teams can conduct TCC (Tyre Compatibility Check) testing on European circuits for a maximum of 9 continuous hours between 9:00 AM and 7:00 PM, but only when there's no championship competition happening. Teams need permission if they want to do it differently.
- Maximum 9 continuous hours allowed per TCC session
- Testing window is 09:00 to 19:00 (9 AM to 7 PM)
- Only permitted on European circuits
- Cannot take place during championship competition weekends
Official FIA Text
TCC may only take place for maximum continuous nine hours between 09:00 and 19:00 on European circuits unless agreed otherwise, while no championship competition is taking place.
