This is a really difficult track though. It all depends on what Alonso does, really. If he catches up to Vettel, there's no doubt a battle will ensue and that will damage the tyres. Also, that 36 is probably the estimated maximum of the tyre in optimal conditions. As we've seen before, when that Pirelli goes off, it goes off completely. He might end up losing multiple seconds on a lap, much like Maldonado earlier this race.
