Pirelli Breaks New Ground with Inaugural Bahrain Wet-Weather Testing Program
Pirelli is set to conduct its first-ever wet-weather tyre evaluation session in Bahrain during late February, with McLaren and Mercedes each contributing a mule car to the initiative. The test represents a significant opportunity for the tyre manufacturer to develop improved intermediate and full wet compound formulations that have long been the subject of industry scrutiny.

The Formula 1 paddock will witness a historic moment as Pirelli embarks on uncharted territory with its maiden wet-weather testing programme, scheduled to take place in Bahrain toward the end of February. McLaren and Mercedes will serve as key partners in this endeavor, each supplying a mule car to support the Italian tyre manufacturer's developmental efforts.
For years, Pirelli has faced mounting pressure from teams and drivers seeking enhancements to its intermediates and full wet-weather tyre range. However, translating that feedback into meaningful improvements has proven challenging due to limited testing opportunities in genuinely wet conditions at traditional F1 venues.
This groundbreaking initiative addresses that persistent logistical hurdle, finally providing Pirelli with a dedicated platform to validate its latest wet-weather compounds and gather comprehensive performance data in real-world conditions. The Bahrain location offers the controlled environment necessary for structured testing while potentially accessing the weather conditions required to evaluate how the tyres perform across varying moisture levels.
The collaboration underscores the sport's commitment to advancing tyre technology and suggests a potential template for future developmental programmes, potentially paving the way for additional wet-weather evaluation sessions down the line.

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

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 C10.8.2
Tyre Specification
Chapter: C10
In Simple Terms
The tyre supplier (Pirelli) decides what tyres F1 cars use, but they need FIA approval. These specifications can't be changed during the season unless the FIA deems it necessary for safety reasons. Think of it as a locked-in agreement to keep competition fair.
- Tyre supplier determines specifications in agreement with the FIA
- Specifications remain fixed throughout the season for competitive fairness
- FIA has emergency authority to change tyres mid-season for safety reasons
- Changes require Formula One Commission approval, except in safety situations
Official FIA Text
Tyre specifications determined by tyre supplier in agreement with FIA. Specification cannot change without Formula One Commission agreement, except FIA may change for safety reasons during season.
Article B11.4

TMC (Test/Marketing Cars) are special F1 cars that teams can run with minimal changes to test new tyres or components for upcoming seasons. These cars can only run for a maximum of nine hours per day between 9 AM and 7 PM, and must follow all safety procedures including red flag rules and fuel handling regulations.
- TMC cars are limited to minimal modifications only
- Used exclusively for testing tyres and components for future championships
- Maximum running time is 9 hours daily between 09:00-19:00
- Must comply with red flag procedures and fuel handling provisions
Official FIA Text
