5.14.3. Tyre Use Regulations
5.14.3.1. The intention of these Regulations is:
(i) To contain costs by limiting the number of tyres that can be purchased on behalf of any one Entrant/Driver during the season,
(ii) To limit the number of tyres used per car/Driver per complete Event, 4 (four) nominated ‘new’ slick tyres and 4 (four) nominated ‘used’ tyres,
(iii) To prohibit the use of any method of raising the temperature of tyres by adding heat artificially, (iv) To prohibit the application of any material to alter the standard performance of the tyres.
Any attempt whatsoever to circumvent these intentions or any fraudulent attempt to deface, re-mark, counterfeit, or otherwise circumvent the unique tyre numbering system will automatically be the subject of a report to the Championship Clerk of the Course.
5.14.3.2. Dry weather, (slick) controlled tyres for the 2009 Clio Cup will be marked on one face of the tyre by the appointed tyre marker, with an individual unique serial number that will also be recorded in the Entrant’s/Driver’s Tyre Purchase Record. The Entrant/Driver must also record the bar code number present on all tyres into their Tyre Purchase Record for future reference.
5.14.3.3. Wet weather (treaded) tyres will not be serial numbered and will not be subject to this number limiting Regulation.
5.14.3.4. It shall be the sole responsibility of the Entrant/Driver to judge whether the track is wet enough to justify the use of wet weather (treaded) tyres.
The Championship Clerk of the Course will not judge whether the track is wet enough to justify the use of wet weather (treaded) tyres.
5.14.3.5. ‘New’ tyres required for use in free practice, qualifying sessions, races and Renault Sport UK official test days may only be purchased:
(i) From the approved supplier (Michelin UK),
(ii) If at the time of purchase, the Entrant’s/Driver’s Tyre Purchase Record for the car onto which tyres are to be fitted is presented for inspection and allocation of tyre identification numbers.
5.14.4. A ‘used’ tyre is defined as a tyre that is visibly worn, been subjected to at least one heat cycle and nominated at a previous Event.
5.14.5. Limitation on Use
5.14.5.1. The maximum number of ‘new’ slick tyres permitted for the 2009 Clio Cup for each Entrant/Driver is: 60 (sixty) slick tyres.
5.14.5.2. In the event that an Entrant/Driver registers for the Championship after the first Renault Sport UK official test day, their tyre allocation will start from the average tyre number of all other registered Entrants/Drivers. Where this calculation results in a decimal point the number will be rounded up to the next whole number.
5.14.5.3. The limit on the number of tyres has been set to allow for both normal wear and for possible accident or puncture damage. Under all normal circumstances the limit of 4 (four) nominated ‘new’ slick tyres for each complete Event will not be exceeded. Except at the first round of the Championship, where it will be permitted for 6 (six) ‘new’ tyres to be presented. In the event that an Entrant/Driver registers for the Championship after the first round, the ‘used’ tyres will be selected at the discretion of the Series Eligibility/Safety Scrutineer or his appointed representative.
5.14.5.4. For each single race Event a maximum of 6 (six) slick (new and used) tyres must not be exceeded, and for each double race Event a maximim of 8 (eight) slick (new and used) tyres must not be exceeded.
5.14.5.5. Only in exceptional cases where, in the judgement of the Series Eligibility/Safety Scrutineer, damage to a maximum of 2 (two) nominated ‘new’ slick tyres makes further participation in an Event impossible, nominated ‘used’ tyres may be substituted. The substitution may only be authorised by the Series Eligibility/Safety Scrutineer.
5.14.5.6. In those exceptional cases where, in the judgement of the Series Eligibility/Safety Scrutineer, damage to tyres through no fault of the Entrant/Driver makes further participation in an Event impossible, supplementary front and/or rear tyres may be nominated and used. Supplementary tyres are to be 2009 ELF Renault Clio Cup

5.14.5.7. It is permitted to use unmarked tyres, complying with Regulation 5.14.1. and Regulation 5.14.2. and purchased from the approved supplier (Michelin UK) at all Renault Sport UK official test days.

5.14.6. Tyre Nomination
5.14.6.1. Each Entrant/Driver must record on the Tyre Nomination Form the serial numbers and the bar code numbers of the 4 (four) ‘new’ nominated slick tyres and the serial numbers and the bar code numbers of the 4 (four) ‘used’ spare tyres that he/she intends to use in an Event.
The Tyre Nomination Form must be signed by the Entrant/Driver and submitted to the Technical Support Vehicle before the first qualifying session. The Series Eligibility/Safety Scrutineer or his appointed representative will sign for receipt and return the back copy. The onus is on the Entrant/Driver to ensure that the completed Tyre Nomination Form is deposited with the Technical Support Vehicle before the first qualifying session. Failure to do so will be the subject of a report to the Championship Clerk of the Course.
5.14.6.2. The tyres nominated in accordance with Regulation 5.14.6.1. must be tyres that have been recorded in the Entrant’s/Driver’s Tyre Purchase Record.
