So, this is the benchmark. The obvious issue is that it’s filled with air. And for something so well-developed - isn’t it weird that it can be rendered entirely useless by something as small as a nail - or even a pothole. But before we get to putting our airless tyres on the car - let me explain how we made them.
So the base is a 14’ steel wheel from a Ford Mondeo, then bolted to the outside are 15 lengths of PVC Fresh Water Pipe. And I know we’re not NASA - but it actually worked well. It's our unique Puncture-Proof Tire System! Using only pvc pipes, nuts and bolts to fit all together.
Now for the clever stuff, these smaller ones are our anti-vibration pipes - to make sure things weren’t too bumpy. Then the grippy bit - this is just the tread from a normal tyre - wrapped around the outside. Then to keep it all together, we used over 300 nuts and bolts.
