Pedrosa`s Michelin technician - Q&A.

The exact tyre selection made on a Thursday before a grand prix is almost a state secret, but could you give us a general description of how the tyres are chosen?

Patrick Isaaco
We take quite a few tyres with different carcasses and rubber compounds, and what we attempt to do is to make the decision according to the weather forecast, knowing whether we are going to have a very hot weekend, or with rain, etc. Moreover, the Michelin tyre engineers and developers in France prepare a preliminary selection of suitable tyre for the circuit in question.

Q:
Where do you think tyre evolution for the MotoGP World Championship is heading?

Patrick Isaaco
Evidently nowadays tyres don't have anything to do with those used years ago because there is continuous research and improvements. Because motorbikes evolve tyre makers have also been forced to evolve. I believe that grip and adherence on corners has improved a lot, things that are totally different from when I began. The motorbikes are completely different, they also have very different demands, so the material evolves in at the same time.

Q:
Electronics have improved rider control, especially in difficult conditions and when using worn tyres. Do these electronic systems place greater demands on the tyres?

Patrick Isaaco
They help the rider to control the machine and therefore less is required from the tyre than when all the power was applied directly to them. Before it was the tyre that received all the power from the engine when the rider used the throttle, but now the power arrives in a more controlled way thanks to the electronics.

Q:
Which are the most critical and demanding circuits for tyres, and why?

Patrick Isaaco
The most critical is Phillip Island, since it is very demanding on the left part of the tyre and requires very rigid tyres on that side. It is something that is very specific for this track, just like in Germany. They also become a critical factor at circuits that have been resurfaced, since we don't know what we will find; and the completely new circuits, this will be the case of Indianapolis this year.

Q:
Which rider has impressed you the most, either because of their riding style or because of how they understood and felt the way that the tyres were working?

Patrick Isaaco
It is difficult to say, but for me the ones that have given me the most information, those that have best transmitted the sensations that they get when out on the track, have been Valentino Rossi and Dani Pedrosa. They have a different way of working from many of the others, this is because they are more sensitive. This doesn't mean that the others don't have sensitivity, but it is a fact that they provide much more information.

Q:
Could you briefly explain how tyre evolution has changed from the 'wild' 500cc two-strokes, to the powerful 990cc four-strokes and then on to the sophisticated 800cc motorcycles?

Patrick Isaaco
The exact evolution would be difficult to explain, but to begin with the motorbikes are completely different regarding the power. The demands made by the engine when changing from 500cc to the [990cc] four strokes, and then to 800cc. In 500cc we changed size to move up to 990cc, since everything evolved depending on the engines. But the truth is that since then every year has seen very big developments.

Q:
What are Dani Pedrosa's tyre preferences, with regard to his riding style and weight?

There's a lot more to tire performance than acceleration, like braking, turning in, turning in while braking, and mid-corner performance. I think people give TC a lot more credit than it deserves.

This brings up an interesting thought (please don''t let this degenerate into another Crash ''I hate x rider-fest''): if the electronics diminishes the rider-tyre reaction, which it surely must do, then how does the rider with more intrusive electronics get to feed-back tyre development info? Seems to me that every ''advance'' in the electronics would add another layer of disconnection between the rider and the tyre technicians so surely there''s a chicken-and-egg thing here. That would mean in turn that the bike with less intrusive electronics could have an advantage if the actual racing takes the bikes outside the programmed ''envelope''. Anybody have any rider-personality-free comments?
