Bridgestone wet tyre compounds available: Soft (Main), Hard (Alternative)
The Sachsenring is one of the most extreme circuits for tyres owing to its abrasive tarmac and long sequence of left-hand turns and its unique layout has produced many thrilling contests since being included on the Grand Prix calendar in 1998.
With ten left-hand turns compared to just three right-handers, the Sachsenring is extremely punishing on the left shoulder of the tyres and the nature of the tarmac can cause high levels of abrasion so the extra-hard front slick option makes its first appearance since the season opener at Qatar.
The imbalance in number of left and right-hand turns at the Sachsenring means asymmetric rear slicks are provided in the medium and hard compound options. However, because of the extreme difference in temperature generated on the shoulders of the tyres - due, in particular, to the sequence of interlinked left-hand corners from turns six to ten - the variance in compound hardness between the left and right shoulders of the rear slicks is one of the largest on the calendar.
Additionally, due to the severity of this track for tyres, Sachsenring, along with Phillip Island is one of only two circuits on the calendar that requires the provision of special construction rear slicks that are specifically developed to cope with the generation of exceptionally high tyre temperatures.
Hiroshi Yamada - Manager, Bridgestone Motorsport Department
“The German Grand Prix is a standout on the calendar both because of its anti-clockwise layout with many left-hand turns and also the large number of close races we have enjoyed here over the years. It is also a significant event for Bridgestone as Germany is a very important market for us and it pleases me very much that the local fans will yet again have a home-grown hero in Stefan Bradl to cheer on during the race.
“As we approach the halfway mark of the season Casey and Jorge are tied in the championship standings so the next couple of races will be hard fought as they both try to gain the upper hand, while Dani won the race here last year and has a good record at the circuit so I expect him to be very strong this weekend.”
Shinji Aoki - Manager, Bridgestone Motorsport Tyre Development Department
“Sachsenring is a technical circuit that features numerous left-hand turns and is run in an anti-clockwise direction. It begins with two slow right-hand corners before opening up into a series of very high-speed long lefts that sweep onto the back straight and then onto the main straight and these left-hand turns, combined with the very abrasive tarmac mean that a good bike setup is essential at this circuit as it is easy to overheat the left side of the tyres, particularly in the rear.
“Though this circuit has one of the lowest average speeds on the calendar, the layout of the circuit generates some of the highest tyre temperatures recorded during the season on the left shoulder of the tyre, while the right shoulder is placed under considerably less stress and must retain adequate temperature during a lap. This means that not only must we provide asymmetric rear tyres with much harder compounds on the left shoulder of the tyre for superior heat and wear resistance, we also utilise a special construction method for the rear slicks to ensure the tyre can manage with the extreme forces sustained at this track. Much like at Qatar, the abrasive track surface also means we provide the extra-hard front tyre option at the Sachsenring alongside the soft and medium compounds.”

Left, left, left, and a little right
The Sachsenring is an anti-clockwise track with an abundance of left-hand turns and a sparse sprinkling of right-handers. This means that the left side of Dunlop’s tyres are subject to far more forces than the right side.
For this reason, the circuit sees the first appearance of the year of the W919 dual compound tyre in addition to the debut of the new ATR14 construction, which is designed to replicate some of the qualities of a dual compound tyre from a single tread compound.
The Sachsenring is located near the foothills of the Ore Mountains, near to the border between Germany and the Czech Republic. A lap has numerous elevation changes through its ten left hand and three right hand turns over its 3.671 km.
Dual Compound time
The one-sided demands of the Sachsenring’s layout mean that Dunlop’s W919 dual compound tyre is unleashed. This features both of the Moto2 core compounds – 3854 soft and 3838 hard – on one tyre. This gives the best of both worlds. The 3838 hard can withstand the frequent calls on the left hand side of the tyre at Sachsenring, whilst the 3854 soft means the right hand side of the tyre is immediately ready to deliver good grip for the few times it is called upon over the course of a lap.
The W919 is allocated along with the 3838 hard, forming a Group E Specials allocation for this meeting. The 3838 comes in a new construction, ATR14 which is asymmetric has been developed to overcome the heat build up on the left working side of the tyre, but also to increase the heat in the lesser working right side of the tyre. This tyre will also fall into the Group E specials and is also under evaluation for the Phillip Island GP in October.
The 3838 compound is the harder option core compound. It gives riders at these circuits the confidence to open the throttle early out of the apex and also adds resistance to abrasion and wear.
The season-familiar front allocation of the 717 and 302 compounds will be on advance party duties.
Dunlop’s Moto2 Operations Manager, Clinton Howe:
“The Sachsenring is a technically interesting circuit. The primary consideration is maintaining enough heat in the less used right hand side of the tyre so it can deliver sufficient grip once it’s called on after being cooled down through not being used over the majority of a lap. This means our tyre designers and compound technicians have to consider the tyre’s heat retention properties.
“This is the first time this season that we use our W919 tyre and it’s also the first race where we will use the new ATR14 construction. The ATR14 has been introduced on the back of rider’s feedback from the 2011 season. We hope to give back a little of the stability lost to a dual compound tyres, while keeping a similar amount of confidence while on the edge of the tyre.
“The Sachsenring is another circuit with a lot of up and down to it, which means a rider demands good stability from the tyre construction especially for any downhill braking. In terms of abrasion the circuit is pretty aggressive so wear rates can be quite high, especially when the temperatures are cool or there has been recent rain. Sachsenring’s location means that the weather can be quite variable, so cool temperatures and rain are never too much of a surprise, nor are hot temperatures, and I know which I’d prefer!”
