You know the familiar tyre walls you see when you’re watching Formula One racing? The ones that are strategically placed around the track, calculated to take the impact of an out-of-control car travelling at more than 300km an hour?
If you've never actually noticed them before, they are always placed behind the orange-and-white barriers, which in turn are strategically placed around danger zones, especially near the gravel traps on corners.
I have to confess that I’d never given their construction a thought, until I shot these sequence of images just before the 2008 Australian Formula One Grand Prix.
I was driving around the Albert Park circuit an hour before it was closed for the race - and kept stopping to shoot frames of the everyday street circuit that the world sees each year in March as the opening grand prix of the season.
That’s when I stopped and took note of exactly how the tyre walls are constructed. Each tyre is carefully placed on top of the other and as you can see from the photograph below, they are chained together for better qualities of shock absorption.
You'd better hurry - they're going quick. Real quick.
