New MotoGP Tire Regulations to Come into Effect at Brno

Starting with the Czech Grand Prix, Bridgestone will offer riders a greater choice of softer compounds, as the new tire supply regulations come into effect. Thus, every rider will now have a choice of three compounds of front slicks with an additional soft compound option being made available for increased safety in the case of low ambient and track temperature.

Furthermore, every rider will also have a choice of rear slick tire compounds and they are also asymmetric for the first time in the single supply era.

The previous regulations permitted two compound options of front and rear slicks and eight front and ten rear slick tires per rider per weekend.

“The surface at Brno is very abrasive so poses quite a challenge for tire durability, demanding harder compounds especially in the front. However from this race onwards our new tire supply system comes into effect meaning that in addition to our ‘core’ compounds we also provide every rider with softer front slicks. The weather in the region can be quite cool so I hope these changes will be well received,” explained Hirohide Hamashima – Assistant to Director, Motorsport Tyre Development Division.

“The circuit is generally fast and flowing so the lateral loads generated are high, particularly in the right shoulders. The elevation changes challenge the front tyres, especially into the downhill corners where the weight transfer creates extra load. The medium speed corners require good shoulder stability from the rear tyres and good traction on corner exit, and excess sliding around the flowing lap can rapidly accelerate tyre wear given the abrasiveness of the tarmac.”
