Airless tyres that never go flat or need to be inflated: It’s a decades-long dream that manufacturers hope to turn into a reality soon, but for truck drivers first. The challenges that the technology faces were put on display at a Goodyear test track in Luxembourg, where a group of journalists put a Tesla equipped with airless tyres through its paces.
Instead of being filled with air, the tyres have a web of spokes that keep the wheels firm and give them a see-through look. The thin layer of rubber gripping the asphalt has a gargantuan physical challenge to meet: supporting the weight of the car and absorbing shocks as well as standard pneumatic tyres for thousands and thousands of kilometres.—APP
