Superbike & Supersport World Championships
Changes to the Technical Regulations – Tyres

The following amendments to the Superbike and Supersport Technical Regulations have been approved:

2.4.6.7 Tyres (Superbike)

1) Tyres may be replaced from those fitted to the homologated motorcycle.

2) The use of tyre warmers is allowed.

3) At each event, during free practices, qualifying practices, Superpole, warm up and races, a maximum of 15 rear and 11 front tyres may be used. Front and rear wet tyres will be included in the total quantity count. A Technical Steward must mark all of these tyres.

During free practices, qualifying practices, Superpole, warm up and races, no motorcycle may enter the track without the front and rear tyres being marked.

If the riders are given a red flag during a race (or during the Superpole for reasons beyond rider’s control) the FIM Technical Director may allow an additional set of tyres to be used.

For each race, one extra set of tyres can be put on the second motorcycle to have it ready for substitution on the grid in case of failure of the first motorcycle.

4) The competitors must use only the tyres distributed during the event by the Official Supplier.

All tyres to be used must be easily identifiable with a colour marking or a numerical system to be applied by the Official Supplier at the time of manufacturing.

At the beginning of the event, the Official Supplier must deliver to the FIM Technical Director 4 samples of each type of tyre which will be used at the event.

When the Official Supplier delivers the samples of the tyres to the FIM Technical Director, he must also give a written explanation of the marking and the general characteristics of the different types of tyres.

The FIM Technical Director may, at his discretion, require the exchange of one or more competitors’ tyres for a tyre sample under his control. The tyres exchanged remain under his control and he can exchange them for the ones of another competitor.

2.5.6.7 Tyres (Supersport)

1) Tyres must be a fully moulded type carrying all size and sidewall marking of the tyres for commercial sale to the public. Tyres of V and Z rating must be used. The depth of the tyre treads must be at least 2.5 mm over the entire tyre pattern width at a pre-race control. The tyres must have a positive and negative tread of 96% positive and minimum 4% negative (land and sea ratio). The maximum distance from the external edge of the tyre to 50% of the tread elements is 35 mm.

One size for the front and two sizes for the rear are allowed. Each size, front and rear, must be available with the same tread pattern as the commercial tyres for the road use. The manufacturers may only submit one front and rear pattern for approval. The previously approved tyre pattern will remain valid until one year after the introduction of a new approved tyre pattern.

The FIM/CCR will grant the approval. The manufacturers must submit the tyre for approval 30 days prior to its first use. Templates proving the land and sea ratio must be included. The tyres must have a DOT and/or E mark. The DOT and/or E mark must appear on the tyre sidewall.

Only when a race or practice has been declared “wet”, the use of a special tyre commonly known as a full wet tyre is allowed. Wet tyres must be a fully moulded tyre, no hand cutting is allowed on moulded tyres. The use of hand cut tyres is not allowed. Wet tyres do not need to carry DOT or E marks; however these tyres must be marked “Not for Highway Use” or “NHS”.

At each event, during free practices, qualifying practices, warm up and the race, a maximum of 11 rear and 9 front tyres may be used. A Technical Steward must mark all of these tyres.

During free practices, qualifying practices, warm up and the race, no motorcycle may enter the track without the front and rear tyres being marked.

If the riders are given a red flag during the race, the FIM Technical Director may allow an additional set of tyres to be used.

For the race, one extra set of tyres can be put on the second motorcycle to have it ready for substitution on the grid in case of failure of the first motorcycle.

2) The competitors must use only the tyres distributed during the event from the Official Supplier.

All tyres to be used must be easily identifiable with a colour marking or a numerical system to be applied by the Official Supplier at the time of manufacturing.

At the beginning of the event, the Official Supplier must deliver to the FIM Technical Director 4 samples of each type of tyre which will be used at the event.

When the Official Supplier delivers the samples of the tyres to the FIM Technical Director, he must also give a written explanation of the marking and the general characteristics of the different types of tyres.

The FIM Technical Director may, at his discretion, require the exchange of one or more competitors’ tyres for a tyre sample under his control. The tyres exchanged remain under his control and he can exchange them for the ones of another competitor.
