The tires are making some of the riders miserable, imo. During the 500/990 era, feel was about as important as outright performance b/c the 500s were difficult to ride, and the 990s were all about late braking and fast exit speeds (until they developed the 22L bikes). Imo, Bridgestone measure the grip achievable with a contact patch of x and a rubber compound of y. Those two variables create z cornering g's. From there, the engineers decide how hard to make the carcass in order to control the flex and temperature. The result is very hard tire carcasses that only some riders can really make use of.
As Cal Crutchlow has said, everything is the opposite with MotoGP tires. If you lack grip on a Pirelli, you back it off a bit to control the tire temperature and to reduce carcass deformation. If you lack grip on Bridgestones, you attack the corner to get a bit of flex and build some temperature. B/c you are always attacking on Bridgestone tires, it is very difficult to tell when they are about to let go. Many riders have complained about that as well.
Should they change philosophy? Yes. Will they? No. If riders can't easily make he jump from other series, they need to change the tires. MotoGP must siphon the best talent from other series. The current tires are making it very difficult for the reasons Crutchlow cited.
It's really not about making tires that go off. These tires are about as fast as Bridgestone can make them, and they last the tire race distance. They need to make the tires predictable and improve the feel, but they are unlikely to do so b/c it might reduce performance and put MotoGP in WSBKs crosshairs. A lot of people don't realize this, but the Flamminis eliminated the tire war so they could make the tires better. The old tire war in WSBK had many production-relevant restrictions. When they hired Pirelli, they knew they would eventually get the Pirelli-version of a MotoGP prototype tire. Judging by the lap times, I'd say Pirelli is getting pretty close. If Bridgestone can't offer softer tires with better feel, they should at least offer more options for carcass construction to that team owners don't end up with a Marco Melandri or Toni Elias situation on their hands. Those guys are proven GP winners, yet they can't make the Bridgestones work properly.
Good post Lex.
