Pirelli’s Race Rubber Roundup from the Island

Pirelli sent this press release regarding all things tyre related at the 2011 WSBK round at Phillip Island:

A very valuable way to start off the 8th season as official tyre supplier to WSBK, Pirelli brought 2000 tyres to perform two days of testing earlier in the week, with riders testing 2 fronts and 3 rears, some of which were also made available for the race weekend.

Another lot of 3000 Diablo Superbike and Diablo Supercorsa tyres were made available for racing, which included mid-soft (SC1), medium (SC2) and hard (SC3) compound choices for the front and SC0 (soft) and SC1 (mid-soft) tyres for the rear, including a newly developed wider and taller profile. Conditions on track changed radically over the week, starting from 50% humidity and 24-30°C on track, to the 55% humidity and 49°C found during Friday practice and Superpole.

With Sunday morning rain, the SBK and SSP teams prepared for Race 1, having to make setup adjustments for the new conditions: 23°C track temps and 75% humidity. Checa (Ducati) proved strongest all week, having dipped below the 1’31 mark in testing and repeating this feat in Superpole, setting a new best lap of 1’30.882 and took pole position. The “B” medium compound front and “B” mid-soft compound rear were the 1-2 finishers’ tyre selection, although podium finishers Haslam (BMW) and Melandri (Yamaha) opted for the “D” soft compound rear designed just for the Phillip Island, helping Haslam record BMW’s 2nd podium and Melandri’s first for SBK.

Four riders opted to make tyre changes for Race 2: Xaus (BMW), Haga (Aprilia) and Corser (BMW) mounted the “A” soft compound rear, and Checa chose the “B” medium front tyre. In SSP, Fabien Foret set a lap record and Yamaha returned to the Supersport podium with Luca Scassa’s victory, who was in turn followed by Parkes (Kawasaki) and Lowes (Honda).

Tyre difficulties encountered in SSP and also changes from Race 1 to Race 2 in SBK indicate that work needs to continue towards solutions for the humid track conditions endured during the weekend.” –
