Bridgestone develops new tyre allocation for Phillip Island

Bridgestone develops new tyre allocation for Phillip Island

Bridgestone will introduce a brand new tyre allocation for the 2014 Tissot Australian Grand Prix, including a newly-developed asymmetric front slick tyre as the Official Tyre Supplier to MotoGP™ continues its efforts to develop technologies that further enhance rider safety.

According to the Japanese firm, ‘New advances in tyre construction and compound technology have enabled Bridgestone to create a front slick tyre that maintains the braking stability of a symmetric tyre, but with enhanced warm-up performance and edge grip. The asymmetric front slick is composed of two different rubber compounds, with one shoulder composed of a softer rubber compound.’

‘In the case of Phillip Island where there are five right-hand corners compared to seven left-hand corners, this softer rubber zone will be on the right shoulder. The new zoning of different rubber compounds on the front slick means that when the rider reaches a lean angle of approximately 30° in right-hand corners, they begin to use the zone of softer rubber on the front tyre for greater safety and performance while cornering.’

For the Tissot Australian Grand Prix, the asymmetric front slick will be in the soft specification; meaning the left shoulder will use Bridgestone’s soft rubber compound, while the lesser-used right shoulder will utilise the extra-soft rubber compound for superior warm-up potential. This asymmetric front slick will be offered as part of Bridgestone’s standard front tyre allocation for Phillip Island, with the other two options of front tyre in the allocation being conventional, symmetric slick tyres.

The rear slick tyres Bridgestone will allocate to riders at Phillip Island have been developed specifically for the severe demands the Australian circuit places on rear tyres, and will feature developments in construction and compound technology that are not featured at any other circuit on the MotoGP™ calendar.

Further to severe tyre degradation at the 2013 Grand Prix and a subsequent pre-season test at the track at the beginning of 2014, the three rear slick options for Phillip Island - the soft, medium and hard compound - provide the optimal combination of safety, durability and performance to suit the track tarmac following its re-surfacing in late 2012.

Shinji Aoki, Manager of Bridgestone’s Motorcycle Tyre Development Department, commented, "After a concerted effort from our Technical Centre in Japan, we will introduce a brand new tyre allocation for this weekend’s Australian Grand Prix. Since last year’s race at Phillip Island, we have tested at the circuit in a large variety of weather conditions to ensure our tyres will provide excellent durability and performance, while still providing good warm-up performance and usability for the riders."

"Such are the demands placed on the rear tyre at Phillip Island, that our rear slicks for this weekend use compound and construction technology that aren’t used at any other circuit on the calendar. Our test results with these new tyres were encouraging, and I am looking forward to seeing them in a race situation this weekend.

He added, "Our new asymmetric front slick is the result of a long development programme and I am pleased to see this new technology makes its debut in the MotoGP World Championship this weekend. The innovative technology we’ve introduced on this asymmetric front slick will ensure that the riders will still enjoy the same high level of braking stability they associate with our symmetric front slick, but with better grip and warm-up performance while cornering. This development is yet another example of our commitment to continue developing new MotoGP tyre technology."
