I think Michelin was told to make the racing close and unpredictable hence the ....... up of a control tire.
This is shades of the 2012 F1 season when there were 7 different winners in the first 7 races. But once the top teams got a handle on how the tires operated that year, a pecking order was established.
I hate control tires in racing. It's dressed up under the guise of being about "fairness" but you can't make a tire that suits every machine. Instead everyone is designing to the tire and right now we're seeing some teams unable to get on it. That Michelin changed the tire design to suit inline 4 engines should have led to a riot by the fanbase because this is basically tantamount to race fixing by giving a tire to a particularly designed motorcycle in order to try and give it an advantage over those that have different engine configurations.
I bet at the end of the day it all comes down to Carmelo and what he wants out of the product.
Why would they make a bad tire on purpose? It would only subject them to liability and commercial scrutiny.
It would make more sense to design a bunch of different constructions and compounds and let the teams/riders pick the ones they like best. Then let them choose when they receive those tires, in the allocation. The bad teams would maybe get a few extra weekends.
In that kind of a scenario, it’s not scandalous if they change the tires somewhat to help the inline 4 teams because their job is to build tires from which all teams can choose preferred rubber.
Maybe every now and again, Michelin must alter the compounds for safety reasons, and the participants throw their toys out of the pram.
