Could flat tyres soon be a thing of the past?

At Michelin’s labs, the tyres are tested for 24 hours at a time, under different loads and speeds. That’s thousands of miles non-stop. Some spokes deform, some break, but the structures continue to perform safely, Mr Rachita says. “It’s test-learn, test-learn,” he said. “But we’re at a stage that’s given us a huge amount of confidence. This is the real deal.”
