HOMEMADE AIRLESS TIRES IN PVC TUBES, NUTS AND BOLTS
for more than 100 years, regularly tires have been filled with air, work well but cause problems like punctures. thanks to michelin, the industry will – hopefully soon – experience a breakthrough with its unique anti-puncture tire system (uptis), a set of airless tires supposed to be mounted on the next-generation Chevy bolt. the development of these airless tires has been going on for more than a decade, but still nothing reaches production.
Taking inspiration from Michelin, the UK media unveiled and tested their own homemade airless tires, built by a racing driver and a mechanical engineer.
HOME AIRLESS TIRE TEST
for their homemade airless tires, the trained media used a 14-inch steel rim from a Ford Mondeo and, on the outside, 15 lengths of freshwater PVC pipe. smaller anti-vibration pipes have been added on the outside to make sure things run a little smoother. for grip they used wire from a normal tire wrapped around the outside and joined in the middle. to keep it together they used over 300 knots and bolts.
“We were obviously very confident in our creation, but it was the first time the tires had been on a car, so we weren’t sure they would hold up,” motivated media said on the test video. ‘However, we did some homework. we know that the car with driver weighs around 800 kg, so when stationary it’s around 200 kg per wheel. so before pushing them to 100 miles per hour and drifting them around the circuit, we had to see if they would hold up at normal speeds.
the team starts testing the tires, and after the first lap there was an obvious downside – the tires were quite noisy. also the more they drove the tires the more they started to come off, with bits coming out of them.
‘Although our tires were uncomfortable, noisy and prone to losing a few nuts and bolts, we knew we had a better chance on the next test and this was the official media bed of nails test. normal tires wouldn’t stand a chance. but it would finally show why our new airless tires are the future. the test was a definite pass.
they tested the tires on the road with great success, even driving through huge potholes that would likely have resulted in a puncture in normal tires. the last test was a drift, with better than expected results.
they are by no means perfect. yes, they could be a bit quieter and much rounder, but they really hold up to nails, potholes and heavy riding. and for homemade wheels created from a drain pipe, a cut-out tire and a million bolts, that’s not bad.
