From a press release issued by the FIM:

Superbike World Championship
Corrections to the rules

The Superbike Commission, composed of Messrs Claude Danis (FIM), Paolo Alberto Flammini (FGSport) and Giulio Bardi (Team representative), in a meeting held yesterday, made corrections in the text of Art. 2.4.6.7 of the Superbike Technical Rules (nine front tyres instead of eleven – all tyres included in the total quantity count). The new text is the following:

2.4.6.7 Tyres

At each event, during free practices, qualifying practices, Superpole and warm up session, a maximum of thirteen (13) rear and nine (9) front tyres may be used. There is no limitation on the number of tyres for the race. All tyres (slick, intermediate and wet) will be included in the total quantity count. If the riders are given a red flag during the Superpole session for reasons beyond rider’s control the FIM Technical Director may allow an additional set of tyres to be used. At the beginning of the event, the Official Supplier must deliver to the FIM Technical Director four (4) samples of each type of tyre which will be used at the event.
