I think most people understand that tread separation is a very, very rare event.

There are some groups who say that Firestone's tire recall should be expanded. They offer small bits of information but lack the complete picture. These kinds of suggestions will make the situation worse.

Its principle purpose is to help keep occupants inside the vehicle and protected.

If it's a more, I'll say, aggressive rollover, the curtain will come down faster.

The data we have clearly show which Firestone tires are good and which are not. A broader recall is wrong.
