I think the whole idea of introducing a single tyre is to reduce, and tightly control testing, in order to try and even out the costs for the teams.
Well, those are all true, but a single tire provider would also probably make the tires safer, too. See, when there are two competing manufacturers, they have an incentive to "push the envelope", and make tires that are closer to the edge, so that they can beat the other guys. With only a single vendor, they can afford to be more conservative in their tire design.
Not that this will guarantee that something like the Indy situation doesn't come up, of course; it's still not clear how Michelin's problem arose (I saw one rumour on ITV-F1 that it was down to a bad batch of materials), but human error has not yet been outlawed, as far as I know. However, if such an event were to happen again, *all* the teams would be in the same boat, and the FIA wouldn't have "fairness" leg to stand on when it came to e.g. putting in a chicane.
