High-Speed Blow-Out 5th Gear : Season 5 Episode 4

Tiff and Vicki show what happens when tires blow, whether run flats are really any good and whether you can race on run flats. Tom reviews the new Mercedes-Benz SLK. Tiff sees which is faster around a track - a Mini Cooper or a diesel Skoda Fabia. Vicki drives that British amphibious vehicle, the Gibbs Aquada.
