This makes for challenges in terms of tyres handling the driving. This circuit also causes extreme average speed levels, as much as 166 kmph - a record made by Jorge Lorenzo the previous year. Lorenzo owns a 72 point lead in the 10th round of the previous season. He finished ahead of Dani Pedrosa, Andrea Dovizioso, Casey Stoner, and finally Valentino Rossi, who missed his previous four races due to injuries.
On this track, asymmetric slicks are not mandatory when the same load is given on both the left and right shoulders of rear tyres of the bike. Harder front tyres become of necessity to endure the extremely abrasive nature of the circuit tarmac.
Brno's height elevation makes the weight transferring of critical importance, because of the increase in pressure the tyres have to endure. Again, the importance of quality front tyres is underlined by how when going downhill on this track, the entire weight of the bike is thrown forward - especially when brakes are pulled. This is the reason why Bridgestone have chosen especially hardened compound front slicks for the Brno track, otherwise something chosen for only a few races throughout the season.
The corner exit speed plays a greater importance on this track than elsewhere for the reason that it is possible for the bikes to attain high levels of speed and driving ease when on the sudden and steep uphill rising parts of the track. This translates directly into reasonably good traction in the rear for the riders to open the throttle as promptly as they can. Uphill elevation variation helps the tyres in the rear grip better by transferring the load towards the back.
