Tires were another hot point, or, rather, just the opposite. All of riders complained of low grip, and tires came off track looking smooth, almost unused. A slightly slippery surface reveals just how fickle MotoGP tires are, with lack of grip leading to less heat in the tires, which means even less grip, and so on. A vicious cycle. Riders theorized that with the full MotoGP circus in town on the third weekend of April (including Moto2 and Moto3), enough rubber would be laid down to create the grip necessary to make their highly specialized tires work properly.
