29. Supply of Tyres and Tyre Limitations During the Event¶

29.1. Tyre Supply¶

Only tyres from Pirelli, approved and registered by the Promoter and sold at Series Events, will be accepted. Tyres must be ordered and paid by the deadlines set by Pirelli, failing which tyres will not be supplied. For the purposes of this article, 'Event' means any official test Event or round of the Series held during the year.

Only one type (specification and dimensions) of dry-weather tyre and one type of wet-weather tyre will be registered per car.

The list of the approved tyre specifications will be published at the latest two weeks prior to the first Event in the Series.

All tyres must be used as supplied at Series Events by the tyre Manufacturer specified by the Promoter. They must comply with the specifications determined by Article 29.2. Any chemical and/or mechanical treatment of the tyres is prohibited. The original tyre tread and profile must not be modified or cut. Modification to marking, reference, information written on the tyre or any traceability means is forbidden. This includes the barcode, Manufacturer serial number, type of tyre, dimensions and any other relevant items.

Teams must adhere to the limits detailed in the technical booklet issued by Pirelli and received from the Promoter before the first Series Event, as well as to any other Technical Bulletins received during the season. Any failure to do so may be penalised by the Stewards.

Drivers are required to sign the 'Acknowledgement of Risks' form issued by Pirelli before the first time they compete in the Series. A new form must be signed should a driver change Teams. On entering the Series, Teams are required to sign and return the 'Supply Agreement with Teams' issued by Pirelli.

A new tyre is a tyre that has not been previously registered and/or allocated to a car. A set of tyres must comprise two front tyres and two rear tyres.

29.2. Dry and Wet weather tyres¶

Dry-weather tyres: only tyres with no tread pattern are accepted as dry-weather tyres.

Wet-weather tyres: a wet-weather tyre is a tyre which is designed for use on a wet track, and is grooved more than 30% symmetrically around the tyre centre-line and covering a square:

Tyre width:
9 inches	180 x 180 mm
10 inches	200 x 200 mm
11 inches	230 x 230 mm
12 inches	250 x 250 mm
13 inches	280 x 280 mm
14 inches	300 x 300 mm
15 inches	320 x 320 mm
16 inches	345 x 345 mm

Pirelli must provide the Promoter with a 1:1 scale legality drawing of the profile they wish to use. This profile must be registered with the Promoter and will be the only one authorised throughout the season.

29.3. Control of tyres¶

The control of the tyres will be carried out according to a process defined by the Promoter.
The outer sidewall of all tyres which are to be used at a Competition must be marked with an FIA Barcode as identification.
Other than in cases of force majeure (accepted as such by the Stewards), the barcode list of all dry-weather tyres intended for use at an Event must be presented to the Technical Delegate prior to the end of initial Scrutineering.
A used tyre is one that has been registered for a previous Competition with the same car number. For race-by-race Competitors, this is considered to be any previous Event in which the car was entered. Used tyres must be presented to Pirelli for checking and re-registration following the process defined by the Promoter and Pirelli. Pirelli maintains a list of the tyres which have been recorded during the season. Used tyres must be taken to Pirelli for re-registration before any new tyres are fitted.
The use of tyres without appropriate identification is strictly forbidden during the whole Competition.
Any marking applied by Pirelli on the tyres must not be removed by the team.
Note that modifications to the tyres are prohibited by the sporting and technical regulations. Tyres must not be subject to any large deformation or impact. Pirelli would also like to inform all Competitors that purging, as shown in Appendix 12, is strictly forbidden.

29.4. Tyre-heating devices¶

Tyre heating will be authorised for the 2022 season.

The use of heating cupboards for pre-heating the tyres is authorised on the following conditions:

The volume must not exceed 12 m3 and must fit within the Team's allocated area in the paddock.
No part of the cupboard can be situated inside the pit garage, on the pit lane or on the grid. Tyre trollies heated in the cupboard may be stored in the pit garage, but are not authorised on the pit lane or grid.
There must only be one system for heating the interior of the cupboard. It must be a forced air system and must run on fuel oil, electricity or gas. The cupboard must be made from non-flammable materials.
The transportation of tyres must be carried out without thermal protection.

Competitors in Pro-Am or Bronze Cup, if they so wish, may use tyre blankets instead of heating cupboards, on condition that the same restrictions on location and transportation are respected. Please note that such teams may use either blankets or a cupboard but not both during the same Event.

29.5. Joker Tyres¶

a) Cases A, C and D:

Each car competing in the Fanatec GT Challenge Europe powered by AWS Series has an allocation of one joker tyre per Competition, which can be used to replace any tyre which has been damaged or is otherwise unusable.

The use of a joker tyre will only be authorised on information from the Race Director or Stewards that the car was involved in a related Incident or other on-track occurrence, and confirmation from the tyre Manufacturer and/or Technical Delegate that the tyre to be replaced may no longer be safely used. A formal request must be made in writing using the official Joker Tyre form and must include the reference of the damaged tyre and the reference of the tyre replacing it. The form must be signed by the Race Director and Technical Delegate before submission to Pirelli. If no joker tyre is requested during a Competition, the joker tyre allocation for that Competition is considered to have lapsed and cannot be carried over to the next Competition. The joker tyre form must be sent by electronic means (email or Team Messaging System).

a) Case B: CrowdStrike 24 Hours of Spa

Each car competing in the Competition has an automatic allocation of one joker tyre, which can be used to replace any tyre which has been damaged or is otherwise unusable. This can be obtained from Pirelli on simple request, providing the barcode of the tyre to be replaced.

b) All Cases

Apart from the joker tyre, any additional tyres may only be issued with the agreement of the Stewards, on submission of a dossier from the Competitor explaining the situation and with confirmation from Pirelli that the original tyre(s) may no longer be used. Should the Stewards agree such a request, they may impose any penalty they consider appropriate.

29.6. Tyres for full-season entrants¶

29.6.1. Carryover Tyres¶

Carryover tyres are defined as those which were registered for use at a previous Event. In this context, ‘Event’ does not normally include the tyres from the Official Prologue and Spa Prologue, unless these are specifically mentioned elsewhere.

A carryover set of tyres, as referred to for cases A, C and D, may be made up of tyres from various sets registered at previous events. This includes tyres from S7.

Full-season Competitors in the Fanatec GT World Challenge Europe powered by AWS will carry their tyres over between Events regardless of whether they are Sprint or Endurance, with the exception of carry over tyres from the CrowdStrike 24 Hours of Spa, which may only be carried over to subsequent Endurance Events. Nevertheless, in order to be able to cater for different clients in Sprint and Endurance, teams may choose, at the first round of the Sprint Cup and the first round of the Endurance Cup, to request to be considered as a new Competitor. This request must be made by the deadline for ordering tyres and must be communicated both to Pirelli and to SRO.

Full-season Competitors in either the Fanatec GT World Challenge Europe powered by AWS Sprint Cup or the Fanatec GT World Challenge Europe powered by AWS Endurance Cup may, on their first appearance on a race-by-race basis in the other Cup, choose to be treated either as a new Competitor in terms of tyres, or to be considered as a returning Competitor.

29.6.2. Chassis & Car Number¶

Throughout the season, tyres are registered to a specific car number, via the barcodes which are allocated by Pirelli.

Should a car change race number during the season but remain with the same Competitor, the used tyres will be transferred to the new race number.
Should a Competitor change the model of car during the season so that the used tyres are no longer suitable, then the car will be treated as a new Competitor in terms of tyres. However, if the Competitor then reverts to the old model, the previously used tyres must be used.
Should a car be transferred between Competitors, the new Competitor may choose either to retain the used tyres or to be considered as a new Competitor.

29.7. Tyre limitations for Case A: three-hour races (dry-weather tyres)¶

For each car, at their first round of the season, six sets of new tyres (S1 -- S6) may be registered by the time specified in the Official Timetable and may be used during the Competition. One of these sets, S6, may be used in Free Practice and Pre-Qualifying only.

For subsequent Events, all returning cars competing in the Fanatec GT Challenge Europe powered by AWS may register four sets of new tyres at the time specified in the Official Timetable (S1 -- S4), two sets of used tyres from previous Competitions (S5 -- S6) and one addition set of new tyres, S7. Sets S5, S6 and S7 may be used during free practice and pre-qualifying only.

For each car, at their first round of the season, seven sets of new tyres (S1 – S7) may be registered by the time specified in the Official Timetable and may be used during the Competition. Set S7 must be used in Pre-Qualifying only but may be used as a carryover at subsequent events.

For subsequent Events, all returning cars competing in the Fanatec GT Challenge Europe powered by AWS may register four sets of new tyres at the time specified in the Official Timetable (S1 – S4), two sets of used tyres from previous Competitions (S5 – S6) and one additional set of new tyres, S7. Sets S5 and S6 may only be used in free practice. Set S7 must be used pre-qualifying only.

Three sets of the tyres registered as new for the Event, S1, S2 and S3, must be designated for use during qualifying and the Race. - S1 must be used by Driver 1 during Q1 and throughout Driver 1’s stint during the Race; - S2 must be used by Driver 2 during Q2 and throughout Driver 2’s stint during the Race; - S3 must be used by Driver 3 during Q3 and throughout Driver 3’s stint during the Race.

No other tyres may be used than those designated for each Qualifying session, unless the session is declared wet and wet-weather tyres are used. Any Team failing to comply with this will be reported to the Stewards.

If wet-weather tyres are used, there is no obligation to change tyres for each Driver during Qualifying. The obligation to use S1, S2 and S3 by Driver 1, Driver 2 and Driver 3 respectively during the Race remains.

In case of a puncture or other damage, another tyre from those registered for the Competition may be used to replace it. This replacement must be notified to the Technical Scrutineers. For the avoidance of doubt, tyres may be changed at any point during the qualifying session but only the correct tyres designated for the relevant period may be used on track (i.e. S1 during Q1, S2 during Q2, etc.)

Additional clarifications or changes to the tyre limitations may be given in the appendix 1 for the Event or by Sporting note.

29.8. Tyre limitations for Case B (dry-weather tyres)¶

A maximum of 30 sets of tyres, purchased in accordance with Article 29.1, will be marked per car. One Joker tyre is automatically available in accordance with Article 29.5. b) These 30 sets of yres may include two sets of carryover tyres from the Spa Prologue (see Article 30.4)

These sets must be used throughout the Competition, from free practice onwards.

For the qualifying sessions no more than three sets of dry-weather tyres per car may be used, four for cars in the Gold, Silver, Bronze or Pro-Am Cups with four drivers. These tyres must be marked before the start of the qualifying session and a barcode list will be issued by Pirelli.

For cars with four drivers, S1 must be used by Driver 1 during Q1, S2 by Driver 2 during Q2, S3 by Driver 3 during Q3, and S4 by Driver 4 during Q4. For cars with three drivers, Driver 1 and S1 will be void, and S2 will be allocated for Driver 2, S3 for Driver 3, and S4 for Driver 4. No other tyres may be used than those designated for each session, unless the session is declared wet and wet weather tyres are used.

A further new set of tyres (S5) is reserved for pre-qualifying and is the only set of tyres authorised for that session.

In case of a puncture or other damage, another tyre from those registered for the Competition may be used to replace it. This replacement must be notified to the Technical Scrutineers.

For the avoidance of doubt, tyres may be changed at any point during the qualifying session but only the correct tyres designated for the relevant period may be used on track (i.e. S1 during Q1, S2 during Q2, etc.)

An additional set of new tyres (S0) will be authorised for the cars qualifying for the Superpole, on

condition that dry-weather tyres are used during the Superpole, that the car actually takes part in the Superpole and sets a time during the session. An additional barcode list will be issued for this. After the Superpole session this set must be returned to Pirelli and cannot be used at any other point during the Competition. If, for any reason, the S0 set is not used during the Superpole, it will be remarked as one of the 30 sets of slick tyres authorised for that car.

Barcodes of fitted tyres will be sent to the Technical Delegate periodically throughout the Competition and may be checked at any time.

In all cases, any infractions will be penalised by the Stewards

A maximum of two sets of tyres per car may be chosen to be carried over to subsequent Endurance Competitions only.

29.9. Tyre limitations for Case C: 6-hour races (dry-weather tyres)¶

For the 6-hour race, for returning cars competing in the Fanatec GT Challenge Europe powered by AWS or Fanatec GT Challenge Europe powered by AWS Endurance Cup, nine sets of new tyres may be registered at the time specified in the Official Timetable and may be used during the Competition. Used tyres from previous race Events may be used during free practice only. For new Competitors, or for cars competing in the Fanatec GT Challenge Europe powered by AWS Sprint Cup only, ten sets of tyres may be marked at the time specified in the Official Timetable and may be used during the Competition.

Three sets of the tyres registered as new for the Event, S1, S2 and S3, must be designated for use during qualifying and the Race. - S1 must be used by Driver 1 during Q1 and during one of Driver 1’s stints during the Race - S2 must be used by Driver 2 during Q2 and during one of Driver 2’s stint during the Race - S3 must be used by Driver 3 during Q3 and during one of Driver 3’s stint during the Race.

No other tyres may be used than those designated for each Qualifying session, unless the session is declared wet and wet-weather tyres are used. Any Team failing to comply with this will be reported to the Stewards.

If wet-weather tyres are used during Qualifying, there is no obligation to change tyres for each Driver during Qualifying. The obligation to use S1, S2 and S3 by Driver 1, Driver 2 and Driver 3 respectively during the Race remains.

S4 is reserved for the pre-qualifying session and is the only set of tyres that can be used in that session.

In case of a puncture or other damage, another tyre from those registered for the Competition may be used to replace it. This replacement must be notified to the Technical Scrutineers.

For the avoidance of doubt, tyres may be changed at any point during the qualifying session but only the correct tyres designated for the relevant period may be used on track (i.e. S1 during Q1, S2 during Q2, etc.)

4: Note that S7 may be used as a carryover for subsequent events

5: There are no restrictions on changing tyres in qualifying

29.11. Tyre Limitations for Wet Weather Tyres¶

There is no limitation on the number of wet-weather tyres that can be used during any Competition.

For free practice, pre-qualifying and qualifying, wet-weather tyres may be used only after the track has been declared wet by the Race Director, his Deputy or the Clerk of the Course.

For the race, the use of wet-weather tyres is free.

Wet-weather tyres will not be marked and there is no limit on how many of them may be used during any Competition

If wet-weather tyres are used during a race, this replaces the need to use the nominated set of tyres per driver, but if the driver changes back to dry-weather tyres, the driver must use the nominated se.

Any infractions will be penalised by the Stewards.

29.12. Camber and Pressure¶

Values for the Maximum Camber and Minimum Pressure of tyres may be issued or modified during any Event and monitored at any time.

29.12.1 Camber¶

For all Competitions, the maximum negative value for the camber of both rear wheels of the car may be monitored in static condition anytime during the Event, including in Parc Fermé after qualifying and the race(s), and must not exceed -3.5°.

For Competitions according to Cases A, B and C, the maximum negative value for the camber of both front wheels of the car may be monitored in static condition anytime during the Event, including in Parc Fermé after qualifying and the race(s), and must not exceed -4°.

These figures may be altered for any Competition, in particular should there be any changes to the circuit configuration. Any such changes will be announced before the Event but values may be further modified by Stewards’ Bulletin during an Event.

Any car failing to abide by these values will be reported to the Stewards, who will give any available sporting penalty, including a stop-and-go penalty to be taken at the start of the next session, deletion of qualifying lap times or a time penalty after a race.

29.12.2 Pressure¶

Values for the Minimum Pressure of tyres may be issued or modified during any Event and monitored at any time.

29.13. Force Majeure¶

In cases of force majeure and subsequent calendar changes, the precise information concerning tyre use at any particular Event will be given in the form of a Sporting Note from the Sporting Board, and may amend or supersede the information on tyre limitations given in Article 29.

29.14. Tyre Limitations for Paid Test Sessions¶

Tyres for paid test sessions and/or official test sessions must be in conformity with the principles laid down in Article 29.1, namely either new tyres or used tyres from previous Events of the Fanatec GT Challenge Europe powered by AWS Series including Official test sessions. Note that for Paid Test Sessions onlyprevious Events include Official Test Sessions (see article 29.1).

New dry-weather tyres purchased for use during these sessions cannot be marked for use during the Event which the test precedes or any subsequent Event.

Exceptionnally, for the first paid test in Imola, teams are authorized to use, as well as the two sets of new tyres per car purchased for the Event and used tyres from the Paul Ricard Official Test Session, any tyres purchased from Pirelli since February 2022 destined for use in a private test.

The number of new dry-weather tyres will be limited per car, in accordance with the table below. If there are multiple sessions taking place on the same day, the total duration of all the sessions will be calculated in order to give the maximum number of tyres.

Total Duration of paid testing per day Maximum new sets of tyres <= 2 hours 1 set

2 hour but <= 4 hours 2 sets 4 hours but <= 6 hours 3 sets 6 hours but <= 8 hours 4 sets 8 hours TBC

The price per car and the instructions for any such tests will be made available before the relevant Event.
