MotoGP Tire (Tyre) Rules

So, I've been reading and listening about the single tire supplier for
MotoGP and there's one thing I can't quite figure out. They say that
Bridgestone will supply something like 4 different compounds and a
couple different constructions. But, are they going to do like F1
where B'Stone decides which two compounds to bring to each event and
the riders only get to choose between them, or will the riders get
their choice from all the compounds and constructions at each event?

I have to say, the more I hear about how the tires rules are going to
operate the bigger I think this mistake gets. Why couldn't they have
just taken the sensible route that nearly EVERYONE likes of simply
letting the riders make their tire choices on Friday evening instead
of Friday morning. It never made any sense to make them choose tires
before taking a single lap.

I gotta agree with Lorenzo, who says he's most concerned about who
will be doing the development work with Bridgestone.

 

I think this can be made to work, just as the Pirelli rule in WSB has
been made to work. The main thing is that there'll be a set of tyres
available with no favouritism and the same tyres available to all.

But I think there is an issue above and with testing in general. I've
never really been able to work out how testing happens away from the
race weekend. We know Ducati have Guareschi and Canepa riding pretty
much all day every day. Honda have people doing the same thing. In the
past there's been a Ducati-Bridgestone group doing testing. These guys
have to use tyres so presumably they'll have to pay for them. Design
feedback is going to go both ways as the teams try and adjust the bike
to the tyres. And Bridgestone develop the tyres to the bike. This all
before Stoner or Rossi or DaniP actually ride the bike. If the test
teams know what they're doing they'll be creating what they know Stoner
or Rossi or DaniP want. Then there's testing by the riders themselves.
Do they ever ride the bikes away from the official tests and races? How
much time do they spend doing that?

That begins to look like a very large number of tyres. Will any team get
them for free under the new regime and be sponsored by Bridgestone? Will
any of the teams get preferential treatment during testing?
