Dani Pedrosa gives a lecture: this is how the MotoGP rider explains how Michelin tire pressures work


When he talks Dani Pedrosa You need to shut up and listen. This is again shown in ‘DAZN‘during the broadcast of Qatar Grand Prix of MotoGP. The pilot of KTM is explained in an educational way how tire pressures work Michelin and what it looks like from the tire supplier’s side and the drivers’ side.

Michelin “You don’t want the tire to go flat or blow out due to low pressure,” begins ’26’. “A tire is made up of two parts, the casing and the rubber. The casing is the part that resists the whole shape and the rubber is the part that touches the ground and sticks to the other side of the tire. They are two layers “different, the hard part which is the shell and the rubber attached to it. It’s like a sports shoe, where you have the shoe itself and the sole, which is in contact with the ground.”

Detailed tire parts, Pedrosa He added that “in that layer there is a micro-movement because it is coated with glue. When you lower the pressure a lot and the tire is not yet at that temperature, with the traction of the first laps, the two layers sticks to each other and causes them to come off. When peeled off, a layer of air with bubbles is created. This happens when, sometimes, in some races we see piece of tire that has come off. If this happens, there is a risk that the tire will break due to the centrifugal force at 300 km/h, which will generate an expansion of the tire if it comes off. This can be very dangerous for the safety of the pilot. So in turn the important part of Michelin to keep the pressure on and it won’t happen.”

A very complex task for pilots and technicians

The Catalan, test pilot of KTM but he is still active since this season he has already played twice Great prizesSherry and Misano-, he does not forget the hard work that goes into all the pits in search of the best performance: “On the other hand, the drivers and technicians deal with knowing between the minimum margin that marks Michelin -1.88 bar at the front and 1.68 at the rear- and the maximum allowed by the performance. If you go over 2.0 bar, performance and grip drop significantly. Then the riders start to feel that they can’t go as fast, they don’t have control of the bike and they can crash at any moment in every corner.”

In that sense, Pedrosa He added that “the calculation of this margin is very difficult because the window is minimal. To the minimum pressure that must be carried, we must add the aggressive driving and the slipstream. Only in the slipstream, the 2.0 bars of pressure are already increasing and you are to exceed the good number to be in the highest performing percentile”.

“That’s where the pilots, sometimes, try to go out with a little more pressure than the minimum they are Michelin he asked, because they knew he was going to climb through that window. But, the window is so small, it always makes it difficult for teams to get it right and in the right window,” he said.
